Loss of Smell and Taste VA Rating: DC 6275 and DC 6276 Criteria Guide

Under 38 CFR 4.87a, the rating schedule for other sense organs provides two distinct diagnostic codes for chemosensory impairment: Diagnostic Code 6275 for complete loss of sense of smell (anosmia), evaluated at 10%; and Diagnostic Code 6276 for complete loss of sense of taste (ageusia), evaluated at 10%. Each condition carries a single, flat 10% schedular rating. Unlike respiratory or musculoskeletal conditions, there are no intermediate or higher percentage tiers such as 20% or 30% for smell or taste impairment alone.

A note to 38 CFR 4.87a establishes a critical legal requirement: an evaluation under DC 6275 or 6276 is assigned only when there is an anatomical or pathological basis for the condition. Subjective reports of sensory loss without underlying physiological or anatomical corroboration cannot support a service-connected rating. Medical evidence must demonstrate documented structural nerve damage, cribriform plate fracture, traumatic brain injury, chronic severe sinus tissue destruction, or other established pathological mechanisms affecting olfactory or gustatory pathways.

The rating schedule strictly requires complete loss of smell or complete loss of taste to qualify for compensation. Partial impairment of smell (hyposmia) or reduced or distorted taste perception (dysgeusia) does not qualify for a compensable 10% evaluation under DC 6275 or 6276. If testing demonstrates that a veteran retains partial olfactory or gustatory function, the condition does not meet the schedular threshold for a compensable rating.

When a veteran suffers from both complete loss of smell and complete loss of taste, and both conditions are supported by a verified anatomical or pathological basis, they are evaluated separately under DC 6275 and DC 6276. Under the combined ratings table in 38 CFR 4.25 (VA math), two separate 10% ratings combine to 19%, which rounds up to a final combined rating of 20%. Because smell (olfactory cranial nerve I) and taste (facial cranial nerve VII and glossopharyngeal cranial nerve IX) represent distinct physiological sensory systems, rating both does not violate anti-pyramiding rules.

Loss of smell and taste among military veterans frequently stems from head trauma, blast overpressure, facial fractures, or severe chronic upper respiratory disease such as chronic sinusitis (DC 6510 through 6514) or allergic rhinitis with nasal polyps (DC 6522). When seeking service connection on a direct or secondary basis, veterans must establish clear medical causation. Association between conditions does not by itself establish secondary service connection. The evidence must support causation or aggravation in the individual claim through documented clinical records or a qualified medical opinion.
