What Chronic Sinusitis and Rhinitis Are
Chronic rhinosinusitis is inflammation of the sinuses and adjacent nasal mucosa persisting for 12 weeks or longer, with at least two cardinal symptoms (nasal obstruction, anterior or posterior nasal discharge, facial pain or pressure, reduction of smell) and objective evidence of inflammation on endoscopy or CT imaging. Acute sinusitis lasting fewer than 12 weeks does not meet the chronic definition.
Allergic rhinitis is IgE-mediated nasal inflammation in response to airborne allergens, producing sneezing, rhinorrhea, nasal congestion, and nasal pruritus. Vasomotor (non-allergic) rhinitis produces similar symptoms without IgE-mediated allergic sensitization and is often triggered by temperature changes, irritants, or environmental exposures. Bacterial rhinitis is rare and typically associated with structural defects.
How Sinusitis Is Rated (DC 6510-6514)
Chronic sinusitis is rated under five diagnostic codes depending on the sinus involved: DC 6510 (pansinusitis), DC 6511 (ethmoid), DC 6512 (frontal), DC 6513 (maxillary), and DC 6514 (sphenoid). All five use the same General Rating Formula for Sinusitis at 38 CFR 4.97.
0 Percent
Detected by X-ray only - radiographic abnormality without active symptoms.
10 Percent
One or two incapacitating episodes per year of sinusitis requiring prolonged antibiotic treatment (lasting four to six weeks), or three to six non-incapacitating episodes per year of sinusitis characterized by headaches, pain, and purulent discharge or crusting.
30 Percent
Three or more incapacitating episodes per year of sinusitis requiring prolonged antibiotic treatment, or more than six non-incapacitating episodes per year.
50 Percent
Following radical surgery with chronic osteomyelitis, OR near-constant sinusitis characterized by headaches, pain, and tenderness of affected sinus, and purulent discharge or crusting after repeated surgeries.
Note: Definition of Incapacitating Episode
A Note to the General Rating Formula for Sinusitis defines an incapacitating episode as one that requires bed rest and treatment by a physician. Without physician-documented bed rest and physician-administered treatment, an episode does not count as incapacitating for rating purposes. Veterans should obtain matching documentation at the time of each flare.
How Rhinitis Is Rated (DC 6522 / 6523)
Allergic and vasomotor rhinitis are rated under DC 6522. Bacterial rhinitis is rated under DC 6523.
DC 6522 - Allergic or Vasomotor Rhinitis
10 percent: Without polyps, but with greater than 50 percent obstruction of nasal passage on both sides or complete obstruction on one side. 30 percent: With polyps.
DC 6523 - Bacterial Rhinitis
10 percent: Permanent hypertrophy of turbinates and crusting with bleeding. 50 percent: Rhinoscleroma.
Why DC 6522 Often Yields the Higher Rating
Veterans with documented nasal polyposis from chronic rhinitis qualify for the 30 percent rating under DC 6522 regardless of obstruction severity. Documentation should include endoscopic visualization of polyps or imaging confirming polyp presence.
Diagnostic Workup
A defensible claim is anchored in objective evidence.
Sinus CT
Non-contrast sinus CT documenting mucosal thickening, opacification, ostiomeatal complex obstruction, or polyposis. The Lund-Mackay score quantifies disease burden and can support severity ratings. CT findings are the gold standard for chronic rhinosinusitis diagnosis.
Nasal Endoscopy
Otolaryngology endoscopic examination documenting mucosal edema, polyps, purulent discharge, or anatomic obstruction. Endoscopy distinguishes polyposis from non-polyp chronic rhinosinusitis.
Allergy Testing
Skin prick testing or serum specific IgE testing identifies environmental allergens and supports the diagnosis of allergic rhinitis when symptoms correlate with documented sensitization.
Pulmonary Function Testing
Spirometry is relevant when comorbid asthma is suspected or claimed. Many veterans with chronic upper airway disease have associated lower airway disease.
Treatment Records
Antibiotic courses, oral or intranasal corticosteroids, antihistamines, leukotriene modifiers, immunotherapy, and surgical interventions (functional endoscopic sinus surgery, septoplasty, turbinate reduction, polypectomy) document severity and course over time.
Service Connection Pathways
Veterans claim sinusitis and rhinitis through several pathways.
Direct Service Connection from In-Service Onset
Sinusitis or rhinitis documented during service or arising shortly after with continuity of symptomatology can establish direct service connection. Service treatment records documenting upper respiratory infections, sinusitis episodes, or chronic congestion are foundational evidence.
Burn Pit and Airborne Hazard Exposure
Under the PACT Act, veterans with qualifying service in Southwest Asia, Afghanistan, or other listed locations may pursue chronic sinusitis, chronic rhinitis, and other chronic upper respiratory conditions as presumptive conditions tied to airborne hazard exposure. Veterans should review their service dates and locations against the PACT Act presumptive list.
Gulf War Presumptive
Under 38 CFR 3.317, certain chronic upper respiratory symptoms in Southwest Asia theater veterans may be evaluated as presumptive medically unexplained chronic multisymptom illness when the symptoms do not match a clear specific diagnosis.
Secondary to GERD or Allergies
Chronic sinusitis can develop secondary to service-connected gastroesophageal reflux disease through chronic post-nasal acid exposure, or secondary to service-connected allergic rhinitis through ostiomeatal complex obstruction.
Evidence That Strengthens the Claim
Strong sinusitis and rhinitis claims include the following.
Specialist Diagnosis
Diagnosis from an otolaryngologist or allergist documenting the specific subtype (chronic rhinosinusitis with or without polyposis, allergic rhinitis, vasomotor rhinitis) using established criteria.
Sinus CT and Endoscopy
Imaging documenting structural and inflammatory changes. Endoscopic findings documenting polyps when present.
Episode Diary and Antibiotic Records
For sinusitis claims under the General Rating Formula, contemporaneous records documenting the frequency of incapacitating and non-incapacitating episodes, antibiotic courses prescribed, and physician-documented bed rest for incapacitating episodes.
Allergy Testing
Skin prick testing or serum specific IgE testing for allergic rhinitis claims.
Treatment Records
Documentation of medical management, immunotherapy, and surgical interventions. Surgical records support 50 percent ratings under DC 6510-6514 when criteria are met.
Exposure Documentation
For airborne hazard claims: deployment locations and dates, unit assignments, MOS, and any documentation of specific exposures (burn pits, sand and dust storms, oil well fires).
Nexus Opinion
A medical opinion that it is at least as likely as not (50 percent probability or greater) that the sinusitis or rhinitis is related to service or to a service-connected condition when direct service connection or presumption does not clearly apply.
Common Rating Issues
Several recurring issues affect sinusitis and rhinitis claims.
Incapacitating Episodes Without Physician Documentation
The Note to the General Rating Formula requires physician-prescribed bed rest and physician-administered treatment. Self-reported bed rest is not sufficient. Veterans should ensure each significant flare is documented in a clinical visit.
Confusing Sinusitis and Rhinitis
Sinusitis and rhinitis are rated separately under different codes. Veterans should ensure both conditions are diagnosed and rated when both are present. Sinusitis without rhinitis, and rhinitis without sinusitis, are both possible clinical patterns.
Polyposis Documentation Gap
The 30 percent DC 6522 rating requires documented polyps. Endoscopic or imaging confirmation is essential. Self-reported "polyps" without provider confirmation may be downgraded to the 10 percent tier.
PACT Act Eligibility Verification
Veterans claiming presumptive service connection through the PACT Act should verify their qualifying service locations and dates against the current presumptive list. The presumptive framework can substantially shorten the evidentiary path.
Related Ratable Conditions
Sinusitis and rhinitis frequently co-exist with other ratable upper and lower airway conditions.
Asthma
Asthma is rated under DC 6602 with criteria based on pulmonary function testing and medication requirements. Chronic upper airway inflammation and lower airway disease commonly coexist ("united airways" concept).
Sleep Apnea
Chronic nasal obstruction can contribute to sleep-disordered breathing. Sleep apnea is rated separately under DC 6847.
GERD
GERD with post-nasal acid exposure can drive chronic rhinosinusitis. GERD is rated under DC 7346.
Vocal Cord Dysfunction
Chronic upper airway inflammation can trigger or aggravate vocal cord dysfunction, rated by analogy under the respiratory codes.
Frequently Asked Questions
Chronic sinusitis is rated under DC 6510-6514 (depending on the sinus involved) at 0 percent (X-ray findings only), 10 percent (one or two incapacitating episodes per year requiring prolonged antibiotic treatment, or three to six non-incapacitating episodes per year), 30 percent (three or more incapacitating episodes per year, or more than six non-incapacitating episodes per year), or 50 percent (following radical surgery with chronic osteomyelitis, or near-constant sinusitis after repeated surgeries). An incapacitating episode requires physician-prescribed bed rest and physician-administered treatment.
Allergic and vasomotor rhinitis are rated under DC 6522 at 10 percent (greater than 50 percent obstruction of nasal passage on both sides, or complete obstruction on one side, without polyps) or 30 percent (with polyps). Documented polyposis on endoscopy or imaging is required for the 30 percent rating regardless of obstruction severity.
Yes. Under the PACT Act, veterans with qualifying service in Southwest Asia, Afghanistan, or other listed locations may pursue chronic sinusitis, chronic rhinitis, and other chronic upper respiratory conditions as presumptive conditions tied to airborne hazard exposure. Veterans should verify their service locations and dates against the current PACT Act presumptive list.
Yes. Sinusitis and rhinitis are separate disabilities rated under different diagnostic codes (sinusitis under DC 6510-6514 and rhinitis under DC 6522 or DC 6523). Veterans with both conditions can receive separate ratings subject to pyramiding analysis under 38 CFR 4.14, which prohibits rating the same disability twice under different codes.
