What is the VA rating for Genitourinary -- Urinary/Renal Conditions?

Review the 3 shared scales (renal dysfunction, voiding dysfunction's 3 independent sub-scales, urinary tract infection) that DC 7500-7545's roughly 40 diagnosis codes dispatch into, including 7 confirmed whichever-is-predominant dispatches, DC 7509's own independent hydronephrosis ladder, DC 7500/7531/7532's minimum-evaluation floors, and DC 7505/7525's tuberculosis cross-reference.

Condition Overview & Clinical Scope

Section 4.115a defines 3 shared rating scales: renal dysfunction (a 5-tier GFR-based ladder), voiding dysfunction (3 independent sub-scales for urine leakage, urinary frequency, and obstructed voiding), and urinary tract infection (a 3-tier ladder). Section 4.115b's roughly 40 diagnosis codes (DC 7500-7545) dispatch into these 3 shared scales in several different ways: some rate directly under one scale, 7 confirmed points dispatch under 'whichever scale is predominant,' DC 7509 (hydronephrosis) has its own independent ladder, DC 7500/7531/7532 each pair a minimum evaluation with the renal scale (DC 7500's and DC 7532's own exact interaction is disclosed as genuinely unstated by the text, not assumed favorable), DC 7507 (nephrosclerosis) has its own 3-way predominant choice including hypertension and heart disease, and DC 7505/7525 dispatch tuberculosis findings to a separate infectious-disease formula.

Overview

About this condition

Section 4.115a defines 3 shared rating scales: renal dysfunction (a 5-tier GFR-based ladder), voiding dysfunction (3 independent sub-scales for urine leakage, urinary frequency, and obstructed voiding), and urinary tract infection (a 3-tier ladder). Section 4.115b's roughly 40 diagnosis codes (DC 7500-7545) dispatch into these 3 shared scales in several different ways: some rate directly under one scale, 7 confirmed points dispatch under 'whichever scale is predominant,' DC 7509 (hydronephrosis) has its own independent ladder, DC 7500/7531/7532 each pair a minimum evaluation with the renal scale (DC 7500's and DC 7532's own exact interaction is disclosed as genuinely unstated by the text, not assumed favorable), DC 7507 (nephrosclerosis) has its own 3-way predominant choice including hypertension and heart disease, and DC 7505/7525 dispatch tuberculosis findings to a separate infectious-disease formula.

Regulatory authority: 38 CFR 4.115a/4.115b, DC 7500-7545

This guide is educational only. RatingScope does not diagnose a genitourinary condition, does not infer missing measurements or lab values, does not determine service connection, and does not predict a VA decision. RatingScope asks which scale is predominant as a direct fact wherever the regulation itself calls for a predominant-scale judgment -- it never infers predominance from symptom severity. DC 7507's hypertension and heart-disease branches are disclosed and cross-linked to the already-built Hypertension and Heart Conditions hubs, never computed here.

Understanding Your Percentage

Select a pathway to see what the published criteria ask about, what records may clarify it, and what should not be assumed.

100%

Highest listed pathway

The highest renal dysfunction tier applies to chronic kidney disease with a very low GFR, regular dialysis, or an eligible kidney transplant recipient, each documented for at least 3 consecutive months during the past 12 months.

What separates the next level: The next tier down (80 percent) requires a GFR between 15 and 29, without dialysis or transplant eligibility.

Review CFR criteria, examples, and evidence
Official CFR language
Chronic kidney disease with glomerular filtration rate (GFR) less than 15 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months; or requiring regular routine dialysis; or eligible kidney transplant recipient.
Qualification explanation
GFR, estimated GFR (eGFR), and creatinine-based approximations of GFR are all accepted for evaluation purposes when determined appropriate and calculated by a medical professional.
Examples
Documented GFR of 12 for the past 4 months.; On regular routine dialysis.; An eligible kidney transplant recipient awaiting or following transplant.
Medical evidence
Nephrology records documenting GFR over time; Dialysis treatment records; Kidney transplant evaluation records
Functional impact examples
Severe, ongoing kidney dysfunction requiring intensive medical management.; Dialysis dependency affecting daily scheduling and activity.
Common misconceptions
A single low GFR reading is not enough; the finding must be documented for at least 3 consecutive months during the past 12 months.; Dialysis or transplant eligibility alone independently qualifies, without needing the GFR threshold as well.

80%

Next: 100%

This tier applies to a documented GFR between 15 and 29 for at least 3 consecutive months.

What separates the next level: Below this range (GFR 30-44) is the 60 percent tier; below 15, or with dialysis or transplant eligibility, is the 100 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Chronic kidney disease with GFR from 15 to 29 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months.
Qualification explanation
The 3-consecutive-month documentation window applies the same way across every renal dysfunction tier.
Examples
Documented GFR of 20 across 3 consecutive lab draws over 4 months.
Medical evidence
Nephrology records documenting GFR over time
Functional impact examples
Significant kidney function loss requiring close monitoring.
Common misconceptions
A single GFR reading in this range without the 3-month documentation window does not establish this tier.

Next: 80%

This tier applies to a documented GFR between 30 and 44 for at least 3 consecutive months.

What separates the next level: Below this range (GFR 45-59) is the 30 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Chronic kidney disease with GFR from 30 to 44 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months.
Qualification explanation
Same 3-consecutive-month documentation window as every other renal dysfunction tier.
Examples
Documented GFR of 38 across the past 4 months.
Medical evidence
Nephrology records documenting GFR over time
Functional impact examples
Moderate kidney function loss.
Common misconceptions
This tier is a moderate-range finding, not a severe one -- it should not be conflated with the 80 or 100 percent tiers.

30%

Next: 60%

This tier applies to a documented GFR between 45 and 59 for at least 3 consecutive months. It is also DC 7500's own flat minimum evaluation for single kidney removal, and DC 7531's floor for kidney transplant residuals.

What separates the next level: Below this range (GFR 60-89 with specific findings) is the 0 percent tier -- a compensable finding still requires documentation, even at 0 percent.

Review CFR criteria, examples, and evidence
Official CFR language
Chronic kidney disease with GFR from 45 to 59 mL/min/1.73 m2 for at least 3 consecutive months during the past 12 months.
Qualification explanation
This is the mildest tier at which chronic kidney disease alone (without additional findings) still qualifies for a compensable renal-dysfunction percentage.
Examples
Documented GFR of 50 across the past 3 months.; Single kidney removal with a flat 30 percent minimum evaluation, regardless of GFR.
Medical evidence
Nephrology records documenting GFR over time; Operative records for single kidney removal
Functional impact examples
Mild-to-moderate kidney function loss.
Common misconceptions
This tier can be reached either through the GFR 45-59 finding or through DC 7500's own flat minimum -- the two routes should not be conflated when documenting evidence.

0%

Next: 30%

This is the lowest documented renal dysfunction tier: a GFR of 60-89 with specific additional findings such as blood cell casts, structural abnormalities, or an elevated albumin/creatinine ratio.

What separates the next level: The next tier up (30 percent) requires a lower GFR range (45-59) without needing an additional finding.

Review CFR criteria, examples, and evidence
Official CFR language
GFR 60 to 89 mL/min/1.73 m2 with red blood cell casts, white blood cell casts, or granular casts, or structural abnormalities on renal imaging studies, or albumin/creatinine ratio greater than or equal to 30 mg/g, for at least 3 consecutive months during the past 12 months.
Qualification explanation
This tier requires a specific additional finding beyond the GFR range alone -- a GFR of 60-89 with no other qualifying finding does not establish even the 0 percent tier under this section.
Examples
GFR of 75 with a documented albumin/creatinine ratio of 35 mg/g across 3 consecutive months.
Medical evidence
Nephrology records documenting GFR, casts, imaging, or albumin/creatinine ratio
Functional impact examples
Early-stage kidney disease markers with normal-range GFR.
Common misconceptions
A 0 percent finding still requires specific documented evidence; it is not simply the absence of any renal finding.

Voiding Dysfunction Scale

Select a pathway to see what the published criteria ask about, what records may clarify it, and what should not be assumed.

60%

Highest listed pathway

The highest voiding dysfunction tier applies to urine leakage requiring an appliance or absorbent materials changed more than 4 times per day.

What separates the next level: Below this (2 to 4 times per day) is the 40 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Urine leakage requiring the use of an appliance or the wearing of absorbent materials which must be changed more than 4 times per day.
Qualification explanation
Voiding dysfunction is rated under whichever of 3 independent sub-scales actually applies -- urine leakage, urinary frequency, or obstructed voiding. This tier belongs to the leakage sub-scale specifically.
Examples
Requires a leg bag or absorbent pads changed 5 or more times daily.
Medical evidence
Urology records documenting leakage frequency and appliance/absorbent-material use
Functional impact examples
Frequent disruption to daily activities from managing leakage.
Common misconceptions
Only one of the 3 voiding sub-scales needs to apply -- documentation does not need to show all 3.
Related topics
voiding dysfunction scale; urine leakage
Source context
38 CFR 4.115a; 7512; Current voiding dysfunction scale.

40%

Next: 60%

This tier applies via either the leakage sub-scale (changed 2 to 4 times daily) or the frequency sub-scale (daytime interval under 1 hour, or 5 or more nightly awakenings).

What separates the next level: Below this on the frequency sub-scale (1 to 2 hour daytime interval) is the 20 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Urine leakage requiring the wearing of absorbent materials which must be changed 2 to 4 times per day; or urinary frequency with a daytime voiding interval less than one hour, or awakening to void five or more times per night.
Qualification explanation
Two different sub-scales can independently reach this same percentage -- the record needs to identify which one actually applies.
Examples
Absorbent materials changed 3 times daily.; Awakening to void 6 times per night.
Medical evidence
Urology records documenting leakage frequency, daytime voiding interval, or nighttime awakenings
Functional impact examples
Sleep disruption from frequent nighttime voiding.; Difficulty planning activities around frequent daytime voiding.
Common misconceptions
When more than one sub-scale finding is documented, the highest applicable tier governs -- it is not an average or a sum.

Next: 40%

This tier belongs to the obstructed-voiding sub-scale: urinary retention requiring intermittent or continuous catheterization.

What separates the next level: Below this is the 10 percent tier for marked obstructive symptomatology without catheterization.

Review CFR criteria, examples, and evidence
Official CFR language
Obstructed voiding: Urinary retention requiring intermittent or continuous catheterization.
Qualification explanation
This is the top tier of the obstructed-voiding sub-scale specifically.
Examples
Self-catheterizes several times daily for urinary retention.
Medical evidence
Urology records documenting catheterization requirement
Functional impact examples
Daily catheterization routine affecting scheduling and privacy.
Common misconceptions
Catheterization itself, not just a retention diagnosis, is what this tier requires.

This tier applies via either the leakage sub-scale (changed less than 2 times daily) or the frequency sub-scale (daytime interval 1 to 2 hours, or 3 to 4 nightly awakenings).

What separates the next level: Below this on the frequency sub-scale (2 to 3 hour daytime interval) is the 10 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Urine leakage requiring the wearing of absorbent materials which must be changed less than 2 times per day; or urinary frequency with a daytime voiding interval between one and two hours, or awakening to void three to four times per night.
Qualification explanation
Two different sub-scales can independently reach this same percentage.
Examples
Absorbent materials changed once daily.; Awakening to void 3 times per night.
Medical evidence
Urology records documenting leakage frequency or nighttime awakenings
Functional impact examples
Some sleep disruption from nighttime voiding.
Common misconceptions
This tier's leakage and frequency routes are independent -- documentation of one does not require the other.

10%

Next: 20%

This tier applies via the frequency sub-scale (daytime interval 2 to 3 hours, or 2 nightly awakenings) or the obstructed-voiding sub-scale (marked obstructive symptomatology with specific findings).

What separates the next level: Below this on the obstructed-voiding sub-scale is the 0 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Urinary frequency with a daytime voiding interval between two and three hours, or awakening to void two times per night; or marked obstructive voiding symptomatology (hesitancy, slow or weak stream, decreased force of stream) with post-void residuals greater than 150 cc, markedly diminished peak flow rate on uroflowmetry, recurrent urinary tract infections secondary to obstruction, or stricture disease requiring periodic dilatation every 2 to 3 months.
Qualification explanation
The obstructed-voiding route at this tier requires at least one of several specific objective findings, not simply a description of stream weakness.
Examples
Awakening to void twice nightly.; Post-void residual of 175 cc documented on bladder scan.
Medical evidence
Urology records documenting voiding interval, uroflowmetry, post-void residual, or stricture dilatation frequency
Functional impact examples
Mild sleep disruption or stream weakness affecting daily function.
Common misconceptions
Subjective complaints of a weak stream alone, without one of the listed objective findings, do not establish the obstructed-voiding route at this tier.

This is the lowest documented voiding dysfunction tier: obstructive symptomatology with or without stricture disease requiring dilatation only 1 to 2 times per year.

What separates the next level: Above this (dilatation every 2 to 3 months, or one of the other listed findings) is the 10 percent tier.

Review CFR criteria, examples, and evidence
Official CFR language
Obstructive symptomatology with or without stricture disease requiring dilatation 1 to 2 times per year.
Qualification explanation
This is the obstructed-voiding sub-scale's own floor tier.
Examples
Stricture dilatation performed once during the past year.
Medical evidence
Urology records documenting dilatation frequency
Functional impact examples
Infrequent obstructive symptoms with minimal treatment burden.

Urinary Tract Infection Scale

Select a pathway to see what the published criteria ask about, what records may clarify it, and what should not be assumed.

30%

Highest listed pathway

The highest urinary tract infection tier applies to recurrent symptomatic infection requiring drainage by stent or nephrostomy tube, more than 2 hospitalizations per year, or continuous intensive management.

What separates the next level: Below this is the 10 percent tier for 1 to 2 hospitalizations per year or 6 months or more of suppressive drug therapy.

Review CFR criteria, examples, and evidence
Official CFR language
Recurrent symptomatic infection requiring drainage by stent or nephrostomy tube; or requiring greater than 2 hospitalizations per year; or requiring continuous intensive management.
Qualification explanation
Any one of the 3 listed routes (drainage device, hospitalization frequency, or continuous management) independently reaches this tier.
Examples
3 hospitalizations for pyelonephritis in the past year.; Nephrostomy tube in place for recurrent infection.
Medical evidence
Hospital admission records; Urology or infectious disease treatment records documenting management intensity
Functional impact examples
Frequent hospitalization disrupting work and daily life.; Ongoing intensive medical management.

Medical evidence
Hospital admission records; Prescription and treatment records documenting suppressive therapy duration

Understand the details behind the criteria

Use these short guides to connect published terms with the records and observations that may clarify them.

The renal dysfunction scale

A 5-tier GFR-based ladder (100/80/60/30/0 percent), each tier requiring documentation for at least 3 consecutive months during the past 12 months.

  • The scale was substantially rewritten to GFR-based criteria effective September 30, 2021, replacing an older BUN/creatinine/albuminuria-based scheme.
  • GFR, estimated GFR (eGFR), and creatinine-based approximations of GFR are all accepted for evaluation purposes when calculated by a medical professional.
  • The 100 percent tier can also be reached through regular routine dialysis or eligible kidney transplant recipient status, independent of the GFR number itself.
  • The 0 percent tier requires a specific additional finding (blood cell casts, structural abnormalities, or an elevated albumin/creatinine ratio) alongside a GFR of 60-89 -- the GFR range alone is not enough.

Records to review: nephrology records; GFR lab results; dialysis treatment records; kidney transplant records.

Voiding dysfunction has 3 independent sub-scales

Urine leakage, urinary frequency, and obstructed voiding are 3 separate sub-scales, never a single uniform ladder -- only whichever particular condition actually applies is rated.

  • Urine leakage is rated by how often absorbent materials or an appliance must be changed (60/40/20 percent).
  • Urinary frequency is rated by daytime voiding interval or nighttime awakenings (40/20/10 percent).
  • Obstructed voiding is rated by catheterization requirement or objective obstructive findings (30/10/0 percent).
  • When more than one sub-scale is documented, the highest applicable tier governs -- this is a judgment call about which single measure best represents the overall voiding dysfunction, not a combination rule that adds the sub-scales together.

Records to review: urology records; voiding diary; uroflowmetry results; post-void residual measurements.

The urinary tract infection scale

A 3-tier ladder (30/10/0 percent) based on hospitalization frequency, drainage requirements, and suppressive drug therapy duration.

  • The top tier (30 percent) is reached through drainage by stent or nephrostomy tube, more than 2 hospitalizations per year, or continuous intensive management.
  • The middle tier (10 percent) requires 1 to 2 hospitalizations per year or 6 months or more of suppressive drug therapy.
  • The floor tier (0 percent) still requires documented recurrent symptomatic infection and suppressive therapy under 6 months.
  • If poor renal function results from the infection, it is rated as renal dysfunction instead of under this scale.

Records to review: hospital admission records; infectious disease or urology treatment records; prescription records for suppressive therapy.

Seven diagnosis codes dispatch under 'whichever is predominant'

DC 7504, 7516, 7527, 7529, 7542, 7545, and DC 7528's own residual clause all rate under whichever of two competing shared scales is predominant.

  • DC 7504 (pyelonephritis) chooses between renal dysfunction and urinary tract infection.
  • DC 7516 (bladder fistula), 7527 (prostate gland disorders), 7542 (neurogenic bladder), and 7545 (bladder diverticulum) each choose between voiding dysfunction and urinary tract infection.
  • DC 7529 (benign neoplasm) chooses between voiding dysfunction and renal dysfunction.
  • DC 7528 (malignant neoplasm), after its temporary 100 percent window ends with no local recurrence or metastasis, also chooses between voiding dysfunction and renal dysfunction for the residual -- the 7th and final confirmed instance.
  • In every one of these 7 instances, which scale is predominant is asked as a direct fact -- it is never inferred from symptom severity or how much evidence happens to be documented for each scale.

Records to review: clinical documentation identifying the predominant finding; urology or nephrology specialist notes.

Section 4.115a's own governing paragraph: predominant-only dispatch, and separate evaluation under §4.14

Before any rating table, 4.115a's introductory paragraph states the general rule behind the 7 confirmed 'whichever is predominant' dispatch points, and a separate rule allowing genuinely distinct, non-overlapping genitourinary disabilities to be rated separately.

  • The governing paragraph's exact text: 'Where diagnostic codes refer the decision maker to these specific areas of dysfunction, only the predominant area of dysfunction shall be considered for rating purposes. Distinct disabilities may be evaluated separately under this section, pursuant to § 4.14, if the symptoms do not overlap.'
  • The predominant-only rule is 4.115a's own general principle -- it is the source of the 7 confirmed 'whichever is predominant' dispatch points elsewhere in this hub, not simply a pattern noticed across individual diagnosis codes.
  • The separate-evaluation half of this rule is not currently computed by RatingScope: this hub does not determine whether two genitourinary findings' symptoms overlap, and does not rate more than one shared scale at once for a single diagnosis code.
  • 38 CFR 4.14 generally prohibits rating the same disability, or the same manifestation of a disability, under more than one diagnostic code (pyramiding) -- 4.115a's cross-reference to it is what allows genuinely distinct, non-overlapping genitourinary disabilities to be evaluated separately instead of being forced through a single predominant scale.

Records to review: clinical documentation distinguishing overlapping vs. distinct genitourinary findings.

Hydronephrosis has its own independent 4-tier ladder

DC 7509 does not use the shared voiding or UTI scales at all -- severe cases dispatch to renal dysfunction, and non-severe cases use hydronephrosis's own colic-frequency scale.

  • Severe hydronephrosis is rated as renal dysfunction directly.
  • Non-severe hydronephrosis uses its own scale: frequent colic with infection (pyonephrosis) at 30 percent, frequent colic requiring catheter drainage at 20 percent, or only an occasional attack of colic (not infected, no catheter) at 10 percent.
  • DC 7508 (Nephrolithiasis/Ureterolithiasis/Nephrocalcinosis) and DC 7511 (Ureter stricture) mostly dispatch to this same hydronephrosis-shaped ladder, except each carries its own override: a documented recurrent-stone-formation-treatment criterion resolves either DC 7508 or DC 7511 to a flat 30 percent instead.
  • DC 7508's override text (procedures more than 2 times per year only) is narrower than DC 7511's (diet therapy, drug therapy, OR procedures more than 2 times per year) -- the two are textually distinct, not interchangeable.

Records to review: urology records documenting colic frequency, infection status, and catheter use; stone-treatment records.

Temporary 100 percent windows and minimum-evaluation floors

DC 7500, 7528, 7531, and 7532 each pair a temporary window or a minimum evaluation with the renal-dysfunction scale, though the exact interaction is not stated in the text for every code.

  • DC 7500 (single kidney removal): the current text reads, in full, "Minimum evaluation 30. Or rate as renal dysfunction if there is nephritis, infection, or pathology of the other." The text does not say whether the 30 percent minimum continues to apply as a floor once the renal-dysfunction scale is triggered, or whether the renal-dysfunction scale fully replaces the minimum. RatingScope discloses both readings rather than asserting either as settled; a prior version of this disclosure stated the more-favorable reading as if it were the regulation's own language, which it is not.
  • DC 7528 (malignant neoplasm): 100 percent applies following treatment, continuing with a mandatory VA examination at 6 months; if there has been no local recurrence or metastasis, the residual is rated as voiding dysfunction or renal dysfunction, whichever is predominant.
  • DC 7531 (kidney transplant): 100 percent applies following transplant surgery, continuing with a mandatory VA examination 1 year after hospital discharge; thereafter, residuals are rated as renal dysfunction with a 30 percent minimum.
  • DC 7532 (renal tubular disorders): the current text reads, in full, "Minimum rating for symptomatic condition 20. Or rate as renal dysfunction." The text does not say whether the 20 percent minimum continues to apply as a floor once the renal-dysfunction scale is triggered, or whether the renal-dysfunction scale fully replaces the minimum, the same genuinely unstated question already disclosed for DC 7500. RatingScope discloses both readings rather than asserting either as settled; a prior version of this disclosure stated the more-favorable reading as if it were the regulation's own language, which it is not. The 20 percent value itself does introduce a rating value that does not exist anywhere else in the standard renal-dysfunction ladder.

Records to review: operative records for kidney removal or transplant; oncology treatment and follow-up records; nephrology records for renal tubular disorders.

Kidney and genitourinary tuberculosis

DC 7505 and DC 7525 both dispatch tuberculosis findings to a separate infectious-disease formula for the active phase, then to §4.88c/§4.89's own time-and-floor mechanic, then to this hub's own residual scale, for the inactive phase.

  • Active tuberculosis is rated a flat 100 percent under 38 CFR 4.88b, DC 6311's General Rating Formula for Infectious Diseases.
  • DC 7505 and DC 7525 use identical cross-reference language for the inactive phase: 'Rate in accordance with §§ 4.88b or 4.89, whichever is appropriate' -- confirmed verbatim from 38 CFR 4.115b. Per RSCH-091, this printed '4.88b' is confirmed to be the same stale pre-1994 section-relabeling artifact already resolved for DC 7911 elsewhere in this hub, not a deliberate reference to the unrelated General Rating Formula for Infectious Diseases -- the veteran-facing rating mechanic these codes actually need is §4.88c or §4.89, matching DC 6010's own correctly-labeled citation in the Eye Conditions hub.
  • Inactive tuberculosis is gated by §4.88c's own 1-year 100 percent floor (entitlement established after August 19, 1968) or §4.89's own 2-year 100 percent floor plus its 6-year and 11-year graduated 50/30 percent floors (entitlement on or before that date, a closed population) BEFORE landing on this hub's own already-built residual scale: renal dysfunction for DC 7505 (kidney tuberculosis), urinary tract infection for DC 7525 (tubercular epididymo-orchitis, prostatitis, urethritis, or orchitis). Corrected under BUG-152 -- earlier RatingScope behavior dispatched every inactive finding straight to the residual scale with no time gating at all, a live accuracy defect that could silently under-rate a veteran still inside a mandatory floor window.
  • §4.89's own text states its graduated rating 'will not be combined with residuals of nonpulmonary tuberculosis unless the graduated rating and the rating for residual disability cover separate functional losses' -- RatingScope discloses this rather than auto-resolving it.
  • DC 7525's non-tubercular branch (the more common case) rates as urinary tract infection directly, with no tuberculosis mechanism involved at all.

Records to review: infectious disease specialist records; tuberculosis treatment and activity-status records, including the date of inactivity and the entitlement-basis date.

Nephrosclerosis's hypertension and heart-disease branches are disclosed, not computed

DC 7507 rates according to whichever of 3 systems is predominant: renal dysfunction, hypertension, or heart disease, with an added elevation rule when the cardiovascular branch applies.

  • This hub computes only the renal-dysfunction branch directly.
  • Choosing hypertension or heart disease as predominant is disclosed as a redirect to the already-built Hypertension and Heart Conditions hubs -- RatingScope does not compute another hub's own rating from within this one.
  • An additional rule applies specifically to the cardiovascular branches: if rated under the cardiovascular schedule, the percentage that would otherwise be assigned is elevated to the next higher evaluation.
  • This elevation rule is a genuinely distinct complexity beyond the ordinary predominant-dispatch pattern used elsewhere in this hub, not simply another instance of it.

Records to review: cardiology records; nephrology records documenting predominant system.

Some diagnosis codes are flat ratings with no shared-scale involvement

DC 7520-7524 and 7543 are rated based on bilaterality or removal-extent facts only, never dispatching to the renal, voiding, or UTI scales.

  • DC 7520 (penis removal, half or more) and DC 7521 (penis removal of glans) are flat 30 and 20 percent, respectively.
  • DC 7522 (erectile dysfunction, with or without penile deformity) is a flat 0 percent, and also covers scarring or deformity of the penis under the same code.
  • DC 7523 (testis atrophy) and DC 7543 (varicocele/hydrocele) are flat ratings based on bilaterality.
  • DC 7524 (testis removal) carries one documented exception: removal of one testis as a service-connected injury or disease, with the remaining testis absent or nonfunctioning for reasons unrelated to service, is rated 30 percent -- the same as removal of both testes -- not 0 percent.

Records to review: urology or reproductive-organ examination records; operative records for removal or atrophy findings.

Measurement Guide

How genitourinary findings are documented

Findings should come from nephrology, urology, or infectious-disease treatment records, lab results, or imaging. RatingScope does not estimate a GFR value, voiding interval, or infection frequency from symptoms alone.

GFR (glomerular filtration rate)

A lab measurement of kidney filtering function, documented over at least 3 consecutive months.

Normal reference: The renal dysfunction scale's 5 tiers are each defined by a specific GFR range.

Why it matters: GFR is the primary determinant of which renal dysfunction tier applies.

Voiding interval and nighttime awakenings

How often urination occurs during the day and how many times sleep is interrupted to void at night.

Normal reference: The urinary frequency sub-scale's tiers are defined by specific daytime interval and nighttime awakening thresholds.

Why it matters: This is one of 3 independent voiding sub-scales; only the sub-scale that actually applies is rated.

Hospitalization and suppressive therapy frequency

How often hospitalization is required for infection, and how long suppressive drug therapy has been used.

Normal reference: The urinary tract infection scale's tiers are defined by hospitalization frequency and suppressive-therapy duration thresholds.

Why it matters: These are the objective criteria the UTI scale actually asks about, distinct from infection frequency alone.

Colic-attack frequency and catheter drainage

How often colic attacks occur for hydronephrosis, and whether catheter drainage or infection is documented.

Normal reference: DC 7509's own independent colic-frequency scale is defined by these specific findings.

Why it matters: Hydronephrosis's own scale is distinct from the shared voiding and UTI scales used elsewhere in this hub.

How an examination adds context

3-consecutive-month documentation window
Every renal dysfunction tier requires the qualifying GFR (or related finding) to be documented for at least 3 consecutive months during the past 12 months, not a single isolated reading.
Predominant-scale facts
For the 7 confirmed 'whichever is predominant' dispatch points, which scale is predominant should be documented directly by a clinician, not inferred from which scale has more supporting evidence on file.
GFR estimation methods
GFR, estimated GFR (eGFR), and creatinine-based approximations of GFR are all accepted when calculated by a medical professional.

Evidence

Evidence that may clarify the published criteria

Kidney Conditions (Nephrology) DBQ

Organizes GFR findings, dialysis status, and kidney transplant status for the renal-dysfunction scale.

A DBQ is useful context, but RatingScope does not require uploads and this hub does not accept records.

Urinary Tract (Bladder and Urethra) Conditions DBQ

Organizes voiding dysfunction and urinary tract infection findings, including leakage frequency, voiding interval, and hospitalization or suppressive therapy history.

A DBQ is useful context, but RatingScope does not require uploads and this hub does not accept records.

Male Reproductive Organ Conditions DBQ

Organizes findings for the flat, non-dispatching ratings (penis, testis, varicocele/hydrocele) and prostate-related conditions.

A DBQ is useful context, but RatingScope does not require uploads and this hub does not accept records.

Nephrology and lab records

GFR results over time, dialysis records, and kidney transplant evaluation records document the renal-dysfunction scale.

A single lab value without the 3-consecutive-month documentation window does not establish a tier.

Urology treatment records

Voiding diaries, uroflowmetry results, post-void residual measurements, and catheterization records document the voiding-dysfunction sub-scales and hydronephrosis's own colic-frequency scale.

Subjective complaints alone, without the specific objective findings the scale asks about, do not establish a tier.

Hospital admission and infectious disease records

Documents hospitalization frequency, drainage procedures, and suppressive therapy duration for the urinary tract infection scale and the tuberculosis cross-reference.

A single infection episode without a recurrent pattern does not by itself establish a UTI-scale tier.

Personal and firsthand lay evidence

Plain descriptions can explain the practical impact of voiding dysfunction, dialysis scheduling, or catheterization routines on daily life.

Lay evidence can describe observed impact, but it should not invent a GFR value, voiding interval, or infection frequency.

Terminology

Plain-English terms

GFR (glomerular filtration rate)

A number that reflects how well the kidneys are working.

The primary determinant of which renal-dysfunction tier applies, documented for at least 3 consecutive months during the past 12 months.

nephrology lab results

Voiding dysfunction

Problems with how, or how often, urination happens.

Only whichever particular sub-scale actually applies is rated; when more than one applies, the highest known tier governs.

urology records; voiding diary

Predominant scale

When a condition could be rated two different ways, which way actually fits best.

7 confirmed diagnosis codes dispatch this way; RatingScope asks for this as a direct fact, never inferring it.

clinical documentation identifying the predominant finding

Hydronephrosis

A kidney that is swollen because urine cannot drain properly.

Severe cases are rated as renal dysfunction; non-severe cases use hydronephrosis's own colic-frequency scale.

urology or nephrology records documenting colic frequency and infection status

Active tuberculosis (genitourinary)

An active TB infection in the urinary or reproductive system, rated differently from inactive TB.

Rated a flat 100 percent under 38 CFR 4.88b, DC 6311, regardless of the genitourinary findings themselves.

infectious disease specialist records

TDIU

Even if the schedular rating for Genitourinary: Urinary and Renal Conditions does not reach 100 percent, TDIU may still provide a pathway to compensation at the 100 percent rate, based on unemployability from this and/or other service-connected disabilities combined.

A lower schedular percentage does not by itself foreclose TDIU eligibility -- this hub computes only the schedular percentage for this specific condition and does not determine TDIU eligibility.

Common Questions

Questions veterans commonly ask

How many different genitourinary conditions does this hub cover?

38 CFR 4.115b assigns roughly 40 diagnosis codes across DC 7500-7545. Most dispatch into 3 shared scales (renal dysfunction, voiding dysfunction, urinary tract infection); a handful have their own independent logic, such as DC 7509's hydronephrosis ladder or DC 7507's 3-way predominant choice.

What does 'whichever is predominant' actually mean?

Seven confirmed diagnosis codes rate under whichever of two competing shared scales is the primary driver of the condition -- for example, DC 7542 (neurogenic bladder) rates as voiding dysfunction or urinary tract infection, whichever is predominant. This is asked as a direct fact, never inferred from symptom severity.

Can I be rated under more than one genitourinary scale at the same time?

38 CFR 4.115a's own governing paragraph says that where a diagnosis code points to more than one shared scale, only the predominant area of dysfunction is considered. It also says distinct disabilities may be evaluated separately under this section, pursuant to 38 CFR 4.14, if the symptoms do not overlap. RatingScope does not currently determine whether findings overlap, and does not rate more than one shared scale at once for a single diagnosis code.

If I've had a kidney removed, is the 30 percent minimum guaranteed?

DC 7500's text reads, in full, "Minimum evaluation 30. Or rate as renal dysfunction if there is nephritis, infection, or pathology of the other." If there is no such finding in the remaining kidney, 30 percent is a flat minimum. If there is, the text does not say whether the 30 percent continues as a floor or is fully replaced by the renal-dysfunction scale. RatingScope discloses both readings rather than assuming the more favorable one.

Is the 20 percent minimum for renal tubular disorders guaranteed?

DC 7532's text reads, in full, "Minimum rating for symptomatic condition 20. Or rate as renal dysfunction." The text does not say whether the 20 percent continues as a floor once the renal-dysfunction scale applies, or is fully replaced by it, the same genuinely unstated question already disclosed for DC 7500. RatingScope discloses both readings rather than assuming the more favorable one.

Why doesn't this hub compute a rating for DC 7507's hypertension or heart-disease branch?

DC 7507 (nephrosclerosis) can be predominantly renal, hypertensive, or cardiac. The hypertension and heart-disease branches belong to the already-built Hypertension and Heart Conditions hubs, so this hub discloses the redirect rather than computing another hub's own rating internally.

What happens with kidney or genitourinary tuberculosis?

Active tuberculosis is a flat 100 percent under a separate infectious-disease formula (38 CFR 4.88b, DC 6311). Inactive tuberculosis is gated by §4.88c's 1-year 100 percent floor (post-1968 entitlement) or §4.89's 2-year 100 percent floor plus its 6-year and 11-year graduated 50/30 percent floors (pre-1968, closed population), before dispatching to this hub's own residual scale (renal dysfunction or urinary tract infection, depending on the diagnosis code).

Is a single low GFR reading enough to establish a renal dysfunction tier?

No. Every renal dysfunction tier requires the qualifying GFR (or related finding) to be documented for at least 3 consecutive months during the past 12 months, not a single isolated lab value.

Is this an active RatingScope assessment?

No. This Genitourinary hub is educational only. Do not enter genitourinary findings into another condition's assessment.

If my schedular rating for Genitourinary: Urinary and Renal Conditions is below 100%, can I still be compensated at the 100% rate?

Possibly, through TDIU (Total Disability rating based on Individual Unemployability, 38 CFR 4.16) -- a separate pathway to 100 percent compensation based on unemployability, from this and/or other service-connected disabilities combined, independent of whether the schedular rating itself reaches 100 percent. This hub computes only the schedular percentage and does not determine TDIU eligibility.

What separates the 100% rating from adjacent levels?

The next tier down (80 percent) requires a GFR between 15 and 29, without dialysis or transplant eligibility.

What separates the 80% rating from adjacent levels?

Below this range (GFR 30-44) is the 60 percent tier; below 15, or with dialysis or transplant eligibility, is the 100 percent tier.

What separates the 60% rating from adjacent levels?

Below this range (GFR 45-59) is the 30 percent tier.

What separates the 30% rating from adjacent levels?

Below this range (GFR 60-89 with specific findings) is the 0 percent tier -- a compensable finding still requires documentation, even at 0 percent.

What separates the 0% rating from adjacent levels?

The next tier up (30 percent) requires a lower GFR range (45-59) without needing an additional finding.
