Loss of Sense of Smell (Anosmia) — VA Disability Rating Criteria (DC 6275)

Diagnostic Code 6275 · 38 CFR §4.87a

What Is It?

Anosmia is the complete loss of the sense of smell. In veterans, this condition most commonly results from traumatic brain injury (TBI) where the olfactory nerves are damaged by head impact, blast exposure causing shearing of the delicate olfactory nerve fibers, exposure to toxic chemicals or burn pit smoke that damages the nasal mucosa, or chronic sinusitis that destroys olfactory tissue. The loss of smell significantly impacts quality of life — veterans with anosmia cannot detect gas leaks, smoke, spoiled food, or other environmental dangers. The condition also severely diminishes the sense of taste since the two senses are closely linked. The VA assigns a single fixed 10 percent rating for complete loss of smell, and this rating does not increase regardless of severity or impact on daily functioning.

Rating Criteria

Evidence Needed

Smell identification test (such as the University of Pennsylvania Smell Identification Test or UPSIT) documenting anosmia or severe hyposmia. ENT examination confirming the loss of smell. Neurological evaluation if the anosmia is related to TBI — this connects the condition to the brain injury mechanism. Service treatment records documenting the causative event: head injury, blast exposure, toxic chemical exposure, or burn pit proximity. MRI of the brain showing any olfactory bulb or frontal lobe damage if TBI-related. Buddy statements from family members describing the impact — inability to smell cooking, gas, or environmental hazards.

C&P Exam Tips

The examiner will likely administer a smell identification test where you are asked to identify different odors from scratch-and-sniff cards or vials. Be honest about what you can and cannot detect — do not guess if you truly cannot smell anything. If your anosmia is related to TBI, make sure the examiner documents the connection to the head injury. Describe the functional impact: inability to detect dangerous situations (gas leaks, smoke, chemical spills), inability to taste food properly, safety concerns at home and work. If you have documentation of normal smell function before the in-service injury, bring it as it strengthens the before-and-after connection.

How to File

File on VA Form 21-526EZ under DC 6275. If anosmia is secondary to a service-connected TBI, file it as a secondary condition linked to the TBI. If caused by toxic exposure or burn pit smoke, reference the PACT Act provisions for toxic exposure presumptives. Include the smell identification test results, ENT evaluation, and documentation of the in-service causative event. Also file for loss of taste (DC 6276) if applicable, as these conditions commonly co-occur.

Common Mistakes

Not getting a formal smell identification test The VA needs objective testing, not just your statement that you cannot smell. Ask your doctor for a UPSIT or similar standardized smell test. Not filing loss of taste as a separate condition Most veterans with anosmia also have impaired taste. DC 6276 (loss of taste) is a separate 10 percent rating that stacks with the anosmia rating. File both. Not connecting anosmia to TBI If your smell loss began after a head injury or blast exposure, it must be linked to the TBI for service connection. Get a nexus opinion from a neurologist. Filing for partial loss when it is actually complete If you have total anosmia, make sure the diagnosis reflects complete loss, not just hyposmia. The test results should clearly show inability to identify odors.

Frequently Asked Questions

Can I get more than 10 percent for loss of smell?

No. DC 6275 has only one rating level: 10 percent for complete loss. However, you can receive additional separate ratings for related conditions — loss of taste (10 percent under DC 6276), the underlying TBI, chronic sinusitis, or secondary depression. These separate ratings combine with the 10 percent for anosmia.

Is loss of smell presumptive for burn pit exposure under the PACT Act?

Anosmia is not currently listed as a specific presumptive condition under the PACT Act. However, the PACT Act established a framework for toxic exposure claims that makes it easier to establish service connection for conditions related to burn pit and chemical exposure. A nexus opinion connecting your anosmia to documented toxic exposures strengthens the claim significantly.

What if my smell loss is partial rather than complete?

Partial loss of smell (hyposmia) can still be rated by analogy under DC 6275 at 10 percent if it is significant enough to impair daily function. The smell identification test will document the degree of loss. Even partial loss that significantly affects your ability to detect dangers or enjoy food may qualify.

Does loss of smell affect my TBI rating?

It depends on how your TBI is rated. If loss of smell is already factored into your TBI residuals rating, you generally cannot receive a separate rating under DC 6275 for the same symptom (pyramiding). However, if your TBI rating is based on other residuals (headaches, cognitive issues) and does not specifically account for anosmia, you can claim it separately.
