Coronary Artery Disease VA Rating: DC 7005 & General Heart Formula

Under 38 CFR 4.104, Diagnostic Code 7005 for arteriosclerotic heart disease (coronary artery disease) is rated under the General Rating Formula for Diseases of the Heart. Ratings are assigned across four discrete tiers: 100% for documented workload of 3 METs or less resulting in dyspnea, fatigue, angina, dizziness, or syncope; 60% for workload of greater than 3 METs but not more than 5 METs; 30% for workload of greater than 5 METs but not more than 7 METs, or objective evidence of cardiac hypertrophy or dilatation; and 10% for workload of greater than 7 METs but not more than 10 METs, or continuous medication required for control. Note that pre-2021 criteria based on left ventricular ejection fraction (LVEF) tiers and chronic congestive heart failure episodes were formally removed from the schedule in November 2021 (86 FR 54089) and no longer apply to rating decisions.

Metabolic equivalents of task (METs) quantify functional cardiac capacity during physical exertion. Under 38 CFR 4.100, application of the General Rating Formula requires laboratory determination of METs by exercise testing (such as a treadmill or bicycle ergometer test), except when medically contraindicated or when a 100% evaluation can be assigned on another basis. When exercise testing cannot be performed for medical reasons, 38 CFR 4.104 Note (2) authorizes the medical examiner to estimate the veteran's METs workload based on specific physical activities that elicit cardiac symptoms. Activities such as slow walking on level ground correspond to 2 to 3 METs, climbing stairs or light yard work corresponds to 4 to 5 METs, and vigorous walking or heavy yard work corresponds to 6 to 7 METs.

A critical provision of the General Rating Formula authorizes a compensable 10% evaluation even if a veteran achieves 10 or more METs without symptoms on exercise testing. If the medical record establishes that daily continuous medication (such as statins, beta-blockers, ACE inhibitors, angiotensin receptor blockers, or nitrates) is prescribed and required for the control of coronary artery disease, the 10% rating tier is legally mandated.

Coronary artery disease is frequently claimed on a secondary basis to service-connected hypertension, diabetes mellitus, or chronic sleep apnea. Prolonged systemic hypertension causes vascular wall strain and accelerated atherosclerosis, while diabetes damages the coronary microvasculature. Association between conditions does not by itself establish secondary service connection. The evidence must support causation or aggravation in the individual claim through a competent medical nexus linking the service-connected disability to the coronary impairment.

A well-supported claim for coronary artery disease requires a completed VA Heart Conditions Disability Benefits Questionnaire, cardiac catheterization reports demonstrating arterial stenosis percentages, exercise stress test reports documenting achieved METs and reason for cessation, echocardiograms detailing left ventricular wall thickness and chamber dimensions, and pharmacy dispensing records verifying continuous daily cardiovascular medications.
