VA Disability Rating for Allergic Rhinitis (DC 6522): Post-9/11 Veterans Guide 2026

DC 6522: The Allergic Rhinitis Rating Structure

VA rates allergic rhinitis under Diagnostic Code 6522 in 38 CFR Part 4, Schedule for Rating Disabilities. The code is deceptively simple — only three rating levels — but the difference between levels is substantial, and the threshold for the highest rating (polyps) is something many veterans don't realize they may have developed.

The critical observation: under DC 6522, polyps are the gateway to a 30% rating. A veteran with severe, debilitating allergic rhinitis without polyps maxes out at 10%. A veteran with even mild rhinitis who has developed nasal polyps is rated at 30%. This is why it's essential to get a thorough ENT evaluation — nasal polyps can develop without dramatic symptoms and may not be visible without nasal endoscopy.

Nasal Polyps: What They Are and Why They Matter for Your Rating

Nasal polyps are benign, soft tissue growths that develop in chronically inflamed nasal and sinus mucosa. They are a common complication of:

• Chronic allergic rhinitis
• Chronic sinusitis
• Aspirin-exacerbated respiratory disease
• Asthma with upper airway involvement
• Chronic exposure to airborne irritants and particulates

Polyps develop gradually — typically over months to years of ongoing mucosal inflammation. This is clinically important for service connection: a veteran who developed allergic rhinitis from particulate exposure during deployment may not have had polyps at the time of separation, but may develop them in the years following discharge as chronic inflammation continues.

Symptoms suggesting possible polyp formation include:

• Progressive worsening of nasal obstruction despite medication
• Significantly reduced or absent sense of smell (anosmia) — polyps can completely block olfactory airflow
• Chronic postnasal drip that persists despite antihistamines and nasal steroids
• Recurrent sinus infections that don't resolve fully
• A sensation of fullness or pressure in the nose that feels like permanent congestion

If you experience these symptoms and have not had nasal endoscopy, request a referral to ENT. The evaluation involves passing a small flexible camera through the nasal passages — it's brief and minimally uncomfortable, and it definitively documents polyp status.

Southwest Asia Particulate Exposure: The Rhinitis Mechanism

The respiratory environment in Southwest Asia — particularly Iraq and Afghanistan — was extraordinarily hostile to the upper airway. Veterans deployed to these regions experienced:

Desert Sand and Dust Storms

Iraq and Afghanistan are among the dustiest environments on earth. The fine particulate matter (PM2.5 and PM10) from desert sand storms penetrates the nasal passages and triggers an inflammatory immune response. Unlike typical seasonal allergic rhinitis triggered by pollen, particulate-induced rhinitis represents non-allergic (vasomotor) rhinitis or mixed-pattern allergic rhinitis sensitized by the physical and chemical properties of the dust.

Military studies have documented that significant percentages of deployed troops developed new-onset rhinitis during or after Southwest Asia deployments. Many of these veterans had no prior history of rhinitis in their home climates.

Burn Pit Smoke

Open-air burn pits at forward operating bases were used to incinerate all waste — medical waste, chemical residue, plastics, electronics, and human waste — producing toxic smoke containing dioxins, particulates, heavy metals, and volatile organic compounds. This chronic smoke exposure directly injured upper airway mucosa and triggered chronic inflammatory responses including rhinitis, sinusitis, and lower airway disease.

Industrial and Chemical Exposures

Post-combat Iraq in particular had extensive oil fire residue, depleted uranium dust, and industrial chemical contamination. Veterans who operated in areas with oil field fires, weapons cache demolitions, or industrial sites had additional chemical exposures contributing to upper airway sensitization.

Vehicle Diesel Exhaust

Diesel exhaust is a potent respiratory sensitizer and is associated with both allergic and non-allergic rhinitis. Vehicle operators and crews in large motor pools were exposed to diesel exhaust at concentrations far exceeding civilian occupational limits.

The PACT Act and Allergic Rhinitis Claims

The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics (PACT) Act, signed into law in August 2022, made sweeping changes to VA's approach to toxic exposure claims for Post-9/11 veterans. Key PACT Act provisions affecting rhinitis claims:

Presumptive Service Connection for Burn Pit Exposure

For veterans who deployed to covered locations (Iraq, Afghanistan, Syria, Djibouti, Egypt, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, UAE, Uzbekistan, and others), the PACT Act creates a presumption that they were exposed to airborne hazards from burn pits. Conditions caused by this exposure — including rhinitis and rhinosinusitis — are subject to presumptive service connection.

Expanded Time Windows

The PACT Act extended the window for veterans to file claims related to toxic exposures and removed some of the barriers that previously required veterans to prove a specific mechanism of exposure.

New Eligibility Categories

Veterans who were previously denied claims for rhinitis citing inability to establish the exact exposure mechanism may be able to reopen those claims under PACT Act authorities. If you were previously denied a rhinitis claim related to Southwest Asia deployment, a supplemental claim under the PACT Act framework may be appropriate.

Service Connection Pathways for Allergic Rhinitis

Veterans with rhinitis have multiple service connection pathways depending on when the condition was first documented:

Direct Service Connection — In-Service Diagnosis

Service treatment records documenting rhinitis, upper respiratory complaints, sinusitis, or nasal congestion treated during deployment provide the clearest path to direct service connection. The nexus from in-service diagnosis to current disability is established by the continuous treatment record.

Presumptive Service Connection (PACT Act)

Post-9/11 veterans who deployed to covered locations and developed rhinitis that was not adequately addressed during service can pursue presumptive service connection under PACT Act authorities, citing burn pit and particulate exposure without needing to prove a specific exposure event.

Direct Service Connection via Nexus Letter

For veterans with post-service rhinitis diagnoses and a documented Southwest Asia deployment, a nexus letter from an ENT or pulmonologist connecting the current rhinitis to the particulate/burn pit exposure provides the medical opinion required for direct service connection when no in-service STR entry exists.

Secondary Conditions: High-Value Claims Flowing from Rhinitis

Allergic rhinitis is anatomically connected to several other conditions that can develop as direct consequences of chronic upper airway inflammation. These secondary claims often carry higher rating values than the rhinitis itself:

Obstructive Sleep Apnea

Chronic nasal obstruction from rhinitis is a recognized risk factor for obstructive sleep apnea (OSA). When nasal passages are obstructed, patients shift to mouth breathing during sleep, which alters airway dynamics and promotes airway collapse. Sleep apnea is rated at 50% when requiring CPAP therapy under DC 6847 — one of the highest-value single secondary claims. Veterans with service-connected rhinitis who have developed sleep apnea should strongly consider filing a secondary claim.

Asthma

The nasal-bronchial reflex connects upper and lower airway inflammation — chronic rhinitis triggers inflammatory mediator release that sensitizes and inflames the lower airways, contributing to asthma development. Service-connected rhinitis causing or aggravating asthma creates a secondary claim valued at 10-100% depending on severity and FEV1 measurements.

Chronic Sinusitis

Allergic rhinitis impairs sinus drainage through mucosal swelling at the ostiomeatal complex — the drainage pathways connecting the sinuses to the nasal cavity. Chronic sinusitis (DC 6510-6514) developing from rhinitis-related drainage obstruction is ratable separately from the rhinitis, provided the symptoms are distinct and not pyramided.

Eustachian Tube Dysfunction and Otitis Media

The Eustachian tube connects the middle ear to the back of the nasal cavity. Nasal mucosal inflammation from rhinitis extends to the Eustachian tube, causing dysfunction that can lead to chronic middle ear problems, hearing muffling, and recurrent otitis media. Hearing loss secondary to Eustachian tube dysfunction secondary to rhinitis is a ratable secondary chain.

Rhinitis vs. Sinusitis: Claiming Both When Appropriate

Many veterans have both allergic rhinitis (DC 6522) and chronic sinusitis (DC 6510-6514) — they are separate but related conditions. VA's pyramiding rule (38 CFR § 4.14) prohibits rating the same disability manifestation under multiple codes, but rhinitis and sinusitis have distinct symptom profiles and can be rated separately:

A veteran who developed both rhinitis and sinusitis from Southwest Asia particulate exposure can and should claim both — as long as a clinician has separately diagnosed both conditions and the symptoms are documented as distinct.

Evidence and Documentation

• Deployment records — DD-214 showing deployment to covered PACT Act locations (Iraq, Afghanistan, etc.)
• Service treatment records — any documentation of upper respiratory complaints, nasal congestion, sinusitis, or rhinitis treatment during service
• Current ENT evaluation — nasal endoscopy with specific documentation of polyp status; the presence or absence of polyps must be explicitly documented
• Allergy testing records — skin prick testing or specific IgE blood tests documenting sensitization patterns
• CT scan of sinuses — CT sinus imaging documents mucosal thickening, polyps, and any structural abnormalities; it's objective evidence VA cannot dismiss
• Treatment records — documentation of ongoing prescription medications (antihistamines, nasal steroids, leukotriene inhibitors, biologics for severe polyp disease)
• Personal statement — description of the in-service dust and burn pit exposure; current symptom frequency and severity; functional impact on sleep, work, and daily activities
• Nexus letter — ENT or allergy/immunology physician opinion connecting the rhinitis to Southwest Asia particulate exposure

C&P Exam Tips for Allergic Rhinitis Claims

• Bring your ENT records. If you've had nasal endoscopy documenting polyps, bring the report. If VA's C&P examiner misses polyps, your independent ENT documentation becomes critical evidence.
• Describe symptom frequency honestly. How many days per week are you symptomatic? Do symptoms affect sleep? Do they affect your ability to concentrate or work? Rate these realistically — not the best days, not the worst, but the average.
• Mention all related symptoms. Tell the examiner about sleep disruption, postnasal drip, recurrent sinus infections, reduced smell, headaches, and ear fullness. Each may support additional secondary claims.
• Connect to your deployment. Explicitly tell the examiner you deployed to [location] and experienced significant dust storm and burn pit smoke exposure. This connects your deployment history to the condition — don't assume it's in the records they'll review.
• Don't undersell medication burden. If you take daily nasal steroids, antihistamines, decongestants, or biologics for rhinitis, describe this. The medication requirement itself reflects the severity of the condition.
