Rhinitis and Sinusitis: VA Disability Ratings & Nexus Letters
Rhinitis and sinusitis are different upper-airway conditions that share symptoms like congestion and nasal discharge — which is why veterans often use one term for both. For VA purposes the distinction matters, because each is rated under different criteria. Your evaluation depends on the diagnosis in your records, your documented symptoms and treatment history, and the applicable rating rules. Where the connection to service is disputed, a medical nexus opinion may be what resolves it.
What Is Rhinitis?
Rhinitis is inflammation of the nasal passages. Common symptoms include congestion, runny nose, sneezing, postnasal drip, and nasal obstruction.
Allergic rhinitis is triggered by an immune response to allergens — pollen, dust, mold, animal dander — and may be seasonal or year-round. Nonallergic rhinitis, sometimes called vasomotor rhinitis, produces similar symptoms without an allergic trigger, and can be provoked by irritants, temperature changes, or airborne particulates. Not every case of rhinitis is allergic, and the distinction affects which diagnostic code applies.
What Is Sinusitis?
Sinusitis is inflammation of the sinus cavities — the air-filled spaces in the bones around your nose and eyes. Typical symptoms include facial pain or pressure, nasal congestion, thick or discolored discharge, reduced sense of smell, and headaches.
Acute sinusitis resolves within weeks. Chronic sinusitis persists for roughly twelve weeks or longer despite treatment, and it’s the form VA evaluates. Because inflammation usually involves both the nasal passages and the sinuses together, clinicians increasingly use chronic rhinosinusitis as the more accurate term.
Chronic sinusitis and rhinitis are not interchangeable diagnoses, even when they feel similar.
What Is the Difference Between Rhinitis and Sinusitis?
Rhinitis primarily involves the nasal passages. Sinusitis involves inflammation extending into the sinus cavities.
The practical difference is what dominates. Rhinitis tends toward congestion, sneezing, and runny nose. Sinusitis tends toward facial pain and pressure, purulent discharge, and recurrent infections requiring antibiotics.
A veteran may have one, the other, both, or a different nasal or sinus disorder entirely. Congestion alone doesn’t establish sinusitis. What your records actually say drives how VA evaluates the claim, which is why an accurate ENT or allergy diagnosis is worth more than a symptom description.
How Does the VA Rate Rhinitis?
Allergic or vasomotor rhinitis is rated under 38 CFR § 4.97, Diagnostic Code 6522:
- 30% — with nasal polyps
- 10% — without polyps, but with greater than 50 percent obstruction of the nasal passage on both sides, or complete obstruction on one side
Those are the only compensable levels under this code. The criteria are anatomical rather than symptom-based, which surprises veterans: how miserable your congestion feels doesn’t determine the rating. Documented obstruction does, and it needs to be measured and recorded by an examiner.
Separate codes exist for bacterial rhinitis and granulomatous rhinitis, which have their own criteria.
How Does the VA Rate Sinusitis?
Chronic sinusitis is rated under the General Rating Formula for Sinusitis, covering Diagnostic Codes 6510 through 6514 depending on which sinuses are involved:
- 50% — following radical surgery with chronic osteomyelitis, or near-constant sinusitis with headaches, pain and tenderness of the affected sinus, and purulent discharge or crusting after repeated surgeries
- 30% — three or more incapacitating episodes per year requiring prolonged antibiotic treatment, or more than six non-incapacitating episodes per year characterized by headaches, pain, and purulent discharge or crusting
- 10% — one or two incapacitating episodes per year requiring prolonged antibiotic treatment, or three to six non-incapacitating episodes per year with those characteristics
- 0% — detected by X-ray only
Two definitions decide almost every sinusitis rating, and both are stricter than veterans expect.
An incapacitating episode means one requiring bed rest and treatment by a physician — that’s the regulation’s own language. Feeling terrible and pushing through work doesn’t meet it. And prolonged antibiotic treatment means a course lasting four to six weeks. A standard seven- or ten-day prescription, however severe the infection felt, generally won’t count.
This is where claims are won and lost. A veteran with genuinely frequent infections may still rate at 0 or 10 percent if the records don’t document episode counts, bed rest, and prolonged antibiotic courses. Records that count episodes and specify treatment duration are worth more than any description of severity.
Chronic rhinosinusitis isn’t separately listed and is generally rated as a type of sinusitis under the most appropriate code in this range.
Can You Receive VA Disability for Both Rhinitis and Sinusitis?
Yes — potentially. This is one of the few areas where the rules work in the veteran’s favor.
Rhinitis and sinusitis are separate diagnostic codes evaluating different anatomy. VA adjudication guidance provides that where both conditions are present and each meets the requirements for service connection, service connection should be granted separately for each, with the ratings then combined.
That said, two limits apply. Each condition has to be separately diagnosed and separately meet its own criteria — a rhinitis diagnosis alone won’t produce a sinusitis rating. And VA’s rule against pyramiding prohibits compensating the same manifestation twice, so overlapping symptoms can’t be counted under both codes.
Practically: if your records document both conditions with the findings each code requires, ask about both. If they document only nasal inflammation, only one applies.
Can Rhinitis or Sinusitis Be Service Connected Secondarily?
Yes. Under 38 CFR § 3.310, a condition caused or aggravated by an already service-connected disability may itself be service-connected — and the relationship can run in either direction.
Rhinitis or sinusitis may be claimed as secondary to another rated condition where the medical evidence supports it. More commonly, service-connected rhinitis or sinusitis serves as the primary condition for other secondary claims. Chronic nasal obstruction, for instance, is recognized in the medical literature as a contributing factor in obstructive sleep apnea — a well-established secondary pathway.
Any secondary relationship has to be established individually, on the medical facts of your case. Co-occurrence establishes nothing on its own, and causation (the primary condition produced the second) differs from aggravation (it worsened a condition you already had, which requires baseline evidence and compensates only the increase).
One route worth checking first. Chronic rhinitis and chronic sinusitis are among the PACT Act presumptive conditions for veterans with qualifying burn pit and airborne hazard exposure. If you’re eligible, VA accepts the service connection without requiring a nexus opinion for the condition itself. Confirm your eligibility on VA.gov before assuming you need one.
What Evidence Supports a Rhinitis or Sinusitis VA Claim?
Requirements vary; no veteran needs everything here.
Service treatment records showing sinus or nasal complaints. A current diagnosis distinguishing which condition you have. ENT and allergy evaluations, including allergy testing where relevant. Imaging — CT is the standard for chronic sinusitis — where clinically appropriate. Nasal examination findings documenting obstruction percentage and any polyps.
For sinusitis specifically, antibiotic prescription records are the highest-value evidence in the file, because they establish both episode frequency and treatment duration. A symptom log recording dates, symptoms, treatment, and any prescribed bed rest speaks directly to what the criteria ask.
Then C&P findings, a completed DBQ, and a nexus opinion where the connection to service is contested.
What Is a Rhinitis or Sinusitis Nexus Letter?
A nexus letter is a written medical opinion addressing whether your current condition is connected to military service, to a specific in-service exposure or event, or to another service-connected condition.
It’s stated using VA’s standard — at least as likely as not, meaning a 50 percent or greater probability. Not every claim needs one. It matters most when service records don’t document the condition, when years separate discharge from diagnosis, when a C&P examiner reached an unfavorable conclusion, when competing causes are in play, or when you’re pursuing secondary service connection and nothing in the file addresses it.
What Should a Rhinitis or Sinusitis Nexus Letter Include?
A useful opinion reads as clinical reasoning about one person.
It should identify the records reviewed, state which condition is diagnosed, and set out the onset timeline, symptom history, and treatment course. It should describe the relevant service history and exposures. It should address alternative causes honestly — environmental allergens, smoking, anatomical variation, post-service occupational exposure — rather than avoiding them. It should apply medical literature where it genuinely fits. And it should address causation and aggravation both, before reaching a clear conclusion with the reasoning that supports it.
A bare conclusion is weak evidence. The reasoning is what an adjudicator weighs.
What Is a Rhinitis and Sinusitis DBQ?
A Disability Benefits Questionnaire is a standardized VA form documenting clinical findings for a condition. The sinusitis, rhinitis, and other conditions of the nose, throat, larynx and pharynx DBQ captures diagnosis, nasal obstruction percentage, polyps, episode frequency, treatment including antibiotic courses, and surgical history.
A DBQ documents severity. It doesn’t establish service connection, and it isn’t required in every claim. It works alongside a nexus opinion rather than replacing one.
What If Your Rhinitis or Sinusitis Claim Was Denied?
Read the decision closely before reacting.
Identify the favorable findings — VA is generally bound by them. Then find the stated reason for denial and determine which element failed. Was there no nexus evidence? Was the diagnosis itself disputed? Or was the denial actually about the rating — obstruction under 50 percent, or episodes that didn’t meet the incapacitating definition? That last one is a different problem needing different evidence, usually better documentation rather than a medical opinion.
Check what VA actually considered, particularly whether your antibiotic records and ENT findings were in the file.
Where the gap is medical, additional medical evidence may address it. Where the issue is procedural, consider working with a VA-accredited attorney, claims agent, or Veterans Service Organization. This page is general information, not individualized medical or legal advice.
Frequently Asked Questions
What is the VA disability rating for rhinitis?
Allergic or vasomotor rhinitis is rated under Diagnostic Code 6522 at 30 percent with nasal polyps, or 10 percent with greater than 50 percent obstruction on both sides or complete obstruction on one side.
What is the VA disability rating for sinusitis?
Chronic sinusitis is rated at 0, 10, 30, or 50 percent under Diagnostic Codes 6510–6514, based on the number of incapacitating and non-incapacitating episodes per year and treatment history.
Can you get VA disability for both rhinitis and sinusitis?
Potentially. They are separate diagnostic codes, and where both are diagnosed and each meets its own criteria, they may be service connected separately and combined — but overlapping symptoms can’t be counted twice.
Do I need a nexus letter for rhinitis or sinusitis?
Not always. A medical opinion helps most when service records don’t document the condition, after an unfavorable C&P opinion, or when pursuing secondary service connection.
What evidence supports a VA rhinitis or sinusitis claim?
A current diagnosis, service treatment records, ENT and allergy findings, imaging, antibiotic and treatment records documenting episode frequency, and a nexus opinion where causation is disputed.
Nexus Veteran MD provides physician-written medical nexus opinions and DBQs for veterans and for the law firms representing them.
For a rhinitis or sinusitis claim, that means individualized review of your service records, ENT and allergy findings, imaging, treatment and antibiotic history, and any prior C&P results — then an honest assessment of whether the evidence supports a favorable opinion, and on which theory. Where it does, the opinion explains the medical reasoning, addresses causation and aggravation where secondary service connection is at issue, and engages the alternative explanations an adjudicator will raise.
Where the evidence doesn’t support a favorable opinion, we say so. That’s what makes the opinions worth submitting.
