Sinusitis VA Rating

Sinusitis is one of the most under-appreciated respiratory claims at the VA. Veterans dismiss it as "just sinus issues," file it as an afterthought to a bigger claim, or skip it entirely. They shouldn't. Maxillary sinusitis alone is the third most common service-connected respiratory disability in VA's fiscal year 2025 Annual Benefits Report, behind allergic rhinitis and sleep apnea. Across 10,382 decided Board rulings on sinusitis from 2021 to 2026, 26.1% were granted, 33.1% denied and 40.9% remanded. A ruling is one issue the Board decided in one decision; one decision often rules on several issues. The rating ladder under 38 CFR § 4.97 runs from zero percent to 50 percent. The 30 percent tier ($552.47 per month for a veteran with no dependents, at the rates effective December 1, 2025) is where documented episodes can take you. And for veterans with qualifying Southwest Asia or post-9/11 service, chronic sinusitis is a presumptive condition.

The PACT Act (38 USC § 1120, with covered service defined in § 1119; VA's regulation at 38 CFR § 3.320 also lists sinusitis) lists chronic sinusitis as a presumptive condition. No nexus letter required. The veteran needs qualifying service in a covered location and a current diagnosis. In the Board's 2021 to 2026 rulings, sinusitis claims that raised a presumption were granted more often than direct claims, yet most sinusitis service connection rulings did not raise one. Many veterans file as a direct claim with a nexus letter, which is the harder path.

There are two other traps that move outcomes. The "incapacitating episode" definition under § 4.97 requires bed rest and treatment by a physician: a veteran sick on the couch with sinus pressure, treating it alone, isn't having an incapacitating episode for VA purposes, no matter how miserable they are. That definition controls the incapacitating-episode routes to the 10 percent and 30 percent tiers; the 50 percent tier depends on surgery, not episode counts. And Diagnostic Code 6522 (allergic rhinitis) sits next to chronic sinusitis in the schedule and tops out at 30 percent instead of 50 percent. When a C&P examiner pins the diagnosis on allergic rhinitis instead of chronic sinusitis, the rating math changes.

This page covers the sinusitis rating chart (DC 6510 to 6514), what counts as an incapacitating episode, how much VA pays, the PACT Act burn pit presumption, how to prove sinusitis is service connected and what a nexus letter needs, sinusitis and rhinitis ratings, secondary conditions such as sleep apnea and migraines, the C&P exam, VA's proposed rating changes, and why VA denies sinusitis claims.

TL;DR

• Across 10,382 decided Board rulings on sinusitis from 2021 to 2026, 26.1% were granted, 33.1% denied and 40.9% remanded. That grant rate is 1.4 points above the Board-wide 24.7 percent.
• Chronic sinusitis is a presumptive condition under the PACT Act (38 U.S.C. § 1120, added 2022) and VA's 38 CFR § 3.320 for veterans with qualifying Southwest Asia or post-9/11 service. No nexus letter required.
• The rating ladder under 38 CFR § 4.97 runs 0%, 10%, 30%, 50%. Fifty percent requires radical surgery with chronic osteomyelitis, or near-constant sinusitis after repeated surgeries.
• The "incapacitating episode" definition is the threshold most veterans miss. It requires bed rest and treatment by a physician. Three or more incapacitating episodes a year, each requiring prolonged (four to six weeks) antibiotic treatment, is one route to the 30% tier; more than six non-incapacitating episodes a year is the other.
• Diagnostic Code 6522 (allergic rhinitis) sits next to chronic sinusitis in the rating schedule and tops out at 30 percent. Allergic rhinitis is a large Board docket of its own. Some of those rulings may involve chronic sinusitis rated under the wrong code.
• When the Board denies sinusitis service connection, the most common reason by far is that the record shows no current diagnosed disability, not a missing nexus.

Sinusitis VA rating criteria (DC 6510 to 6514)

Chronic sinusitis is rated under 38 CFR § 4.97 in the respiratory section of the rating schedule. The diagnostic codes are DC 6510 (pansinusitis), DC 6511 (ethmoid), DC 6512 (frontal), DC 6513 (maxillary), and DC 6514 (sphenoid). They all share the General Rating Formula for Sinusitis.

The sinusitis rating chart

That ladder runs as follows.

• 0%: Sinusitis detected by X-ray only.
• 10%: One or two incapacitating episodes per year requiring prolonged (lasting four to six weeks) antibiotic treatment, OR three to six non-incapacitating episodes per year characterized by headaches, pain, and purulent discharge or crusting.
• 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.
• 50%: 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.

Fifty percent is the highest level the sinusitis formula lists. A complication or a secondary condition with its own diagnosis is rated under its own code and combined with the sinusitis rating.

What counts as an incapacitating episode

The 10% and 30% tiers can both be reached through the count of "incapacitating episodes" per year. The 50% tier does not use episode counts; it requires radical surgery with chronic osteomyelitis, or near-constant sinusitis after repeated surgeries. This is the threshold that most veterans miss when they self-report sinusitis symptoms, and it's the single place where the documentation either earns the higher rating or doesn't.

The note to the formula in 38 CFR § 4.97 reads: "An incapacitating episode of sinusitis means one that requires bed rest and treatment by a physician." Both elements have to be present.

• Bed rest that the episode required
• Treatment by a physician during the episode

A veteran who stays home from work with sinus pain and self-medicates with over-the-counter decongestants is not having an incapacitating episode for VA rating purposes, no matter how miserable they are. A veteran whose doctor writes "patient instructed to remain on bed rest, prescribed antibiotics, follow-up in two weeks" in the chart is.

The non-incapacitating route to the 10% and 30% tiers is more forgiving. Each episode needs headaches, pain, and purulent discharge or crusting, and the episodes have to recur. Three to six episodes per year clears the 10% tier; more than six clears the 30% tier through that path. The Board reads those symptoms together: in decision 24002763 (January 2024) it explained that each listed symptom of a non-incapacitating episode must be present at least to some extent, citing Camacho v. Nicholson, 21 Vet. App. 360 (2007).

Rating appeals at the Board

Most sinusitis appeals at the Board are about service connection, not the tier. The Board section below shows results by what the appeal asked for (service connection, a higher rating, an effective date) and by diagnostic code; maxillary sinusitis, DC 6513, is the code that comes up most often in rating appeals.

How much VA pays for sinusitis

At the rates effective December 1, 2025 (the 2026 rates) for a veteran with no dependents, the dollar values matter.

• 10%: $180.42 per month, $2,165 per year
• 30%: $552.47 per month, $6,630 per year
• 50%: $1,132.90 per month, $13,595 per year

The jump from 10% to 30% is about $4,465 per year, tax-free. The jump from 30% to 50% is another $6,965 per year, tax-free. This is real money over a lifetime of compensation, and the documentation gap between tiers is often a single doctor's note.

Sinusitis also combines with other ratings under VA's combined ratings table in 38 CFR § 4.25, which is not simple addition. The regulation's own example: a 50 percent disability and a 30 percent disability combine to 65 percent, which rounds to 70.

Sinusitis and the PACT Act: the burn pit presumption

Here is the part of the framework most veterans don't know about, and it's the single biggest reason sinusitis filed under the right theory goes better.

In 2022, Congress passed the PACT Act. It added a list of presumptive conditions for veterans with service in covered locations, where exposure to burn pits and other airborne hazards is presumed. Chronic sinusitis is on that list, along with chronic rhinitis and asthma diagnosed after service. The disease list is in 38 U.S.C. § 1120, the covered locations and periods are in § 1119, and VA's regulation at 38 CFR § 3.320 separately lists "sinusitis, to include rhinosinusitis" for veterans with qualifying Southwest Asia and related service.

For a qualifying veteran, presumptive service connection means the following.

• The veteran does not need to prove a nexus between the chronic sinusitis and military service. The link is presumed.
• The veteran does not need a nexus letter for that element of the claim.
• What the veteran needs to show is (a) qualifying service in a covered location and during a covered period, and (b) a current diagnosis of chronic sinusitis.

Who qualifies

Under the statute, a covered veteran is one who served while assigned to a duty station in, including the airspace above, one of these places.

• On or after August 2, 1990: Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, or the United Arab Emirates.
• On or after September 11, 2001: Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Yemen, Uzbekistan, or any other country the Secretary determines relevant.

VA's own rule, § 3.320, covers service in the Southwest Asia theater of operations during the Persian Gulf War (which it defines to include Iraq, Kuwait, Saudi Arabia, the neutral zone, Bahrain, Qatar, the United Arab Emirates, Oman, the surrounding gulfs and seas, and the airspace above them), and service in Afghanistan, Syria, Djibouti, or Uzbekistan on or after September 19, 2001. Under § 3.320 the sinusitis can show up at any time after separation and to any degree, including a noncompensable one. VA can still deny the presumption with affirmative evidence that the disease did not come from that service, that something after service caused it, or that it resulted from the veteran's own willful misconduct.

Filing a PACT Act sinusitis claim

The claim should still be built cleanly. Attach proof of current diagnosis, imaging if available, treatment history, and deployment or service records showing covered location. Make the theory obvious in the claim language. Do not make a rater guess whether this is a direct claim or a PACT Act presumptive claim. The presumptive conditions tool can help check which lists apply to your service.

Compare that to the direct-connection lane, where the veteran has to assemble three things: current diagnosis, in-service event, and a nexus opinion linking the two. Filing a chronic sinusitis claim as a PACT Act presumptive when you qualify takes the hardest part of the case, the nexus, off the table. In the Board's 2021 to 2026 service connection rulings, sinusitis claims that raised a presumption were granted more often than direct claims; the Board section below shows both, and the gap is an association, not proof that the theory caused the result.

Gulf War Illness can cover some broader unexplained symptom clusters, but chronic sinusitis is a diagnosed disease with its own presumption. If the veteran has multiple unexplained symptoms plus sinusitis, both frameworks may need to be considered.

How to prove sinusitis is service connected

When the case isn't presumptive, the veteran is on the direct path or the secondary path, and the claim depends on the medical evidence.

Direct service connection

Direct service connection needs three things: a current diagnosis of chronic sinusitis, an in-service event, injury or exposure, and a medical opinion linking the two. Service treatment records showing sinus complaints, sick call visits for sinus infections, antibiotic courses, a deviated septum or nasal surgery in service, and documented environmental exposure all help show the in-service part.

Nexus letter for sinusitis

If you're on the direct path for sinusitis, the nexus letter is the case. What separates an opinion the Board relies on from one it rejects comes down to a few features.

• Strong nexus opinions include a clear "at least as likely as not" or stronger statement, identify the specific in-service exposure or event, cite supporting medical literature where applicable, address competing causes (smoking, environmental allergens, prior infections, nasal anatomy), and explain the chronicity of the condition.
• Weak nexus opinions state a conclusion without supporting reasoning, fail to address competing causes, rely on a generic statement about military service, or are written by a provider who didn't review the relevant records.

The pattern I see in the decisions I read is that the opinions the Board relies on are specific and reasoned. That is usually what a well-prepared private nexus letter looks like. In the Board's sinusitis rulings, claims with a private medical opinion in the record were granted more often than sinusitis claims overall, an association rather than proof of cause. The Board section below shows how the Board treated the medical opinions in sinusitis claims.

Sinusitis secondary to another service-connected condition

Sinusitis can also be claimed as secondary to an already service-connected condition under 38 CFR § 3.310. In the Board's rulings the most common bases are allergic rhinitis and nasal septum problems. The opinion has to explain how that condition caused the sinusitis, or aggravated it, meaning the sinusitis would be less severe but for the service-connected condition. An opinion that says only "not caused by" and skips aggravation is inadequate (El-Amin v. Shinseki, 26 Vet. App. 136 (2013)).

How to win a sinusitis VA claim

If I were filing or appealing a sinusitis claim today, the action sequence I'd run is structural, not magical.

First, check whether you qualify under the PACT Act presumption. The single highest-yield decision in this entire claim is which lane you file under. If you served in a covered location during a covered period, the presumptive lane takes the nexus element off your plate.

Second, secure a clear current diagnosis. Chronic sinusitis as a diagnosis on the medical record. If your records are ambiguous between sinusitis and allergic rhinitis, an ENT consultation with imaging can clarify it. If you have CT or X-ray findings of mucosal thickening or sinus opacification, that's part of the file the rater needs to see.

Third, document episode frequency and severity in clinical records. Every flare that goes to the primary care office is a data point. The note has to include the date, the symptoms, the treatment given, and where it applies, a bed-rest instruction or an antibiotic prescription. Self-treatment doesn't count as an incapacitating episode. Provider-documented episodes do.

Fourth, if you're on the direct path, get a strong nexus letter. Generic letters that say "Veteran's sinusitis is at least as likely as not related to military service" don't move cases. Specific letters that identify in-service exposures, cite the medical literature, address competing causes, and explain the chronicity of the condition do.

Fifth, consider the secondary chain. Sleep apnea, migraine and asthma are the conditions to look at. If any of these are part of your clinical picture and a doctor can tie them to the sinusitis, the secondary claim under 38 CFR § 3.310 is on the table.

Sixth, consider a hearing if your appeal goes to the Board. Sinusitis rulings where the veteran testified at a Board hearing did a little better than sinusitis rulings overall. That is an association, not a cause, but hearings are particularly useful when the symptom picture is severe but the documentation has gaps the veteran can address in testimony.

Sinusitis and rhinitis VA ratings (DC 6510 to 6514 vs DC 6522)

DC 6522 is allergic or vasomotor rhinitis, not chronic sinusitis, and the rating ladder is different. Worse, in most cases. Under DC 6522, allergic rhinitis rates as follows.

• 10%: Without polyps but with greater than 50% obstruction of nasal passage on both sides, or complete obstruction on one side.
• 30%: With polyps.

That's the entire ladder. There is no 50% tier under DC 6522, and the 30% requires nasal polyps, a specific anatomical finding on examination. Bacterial rhinitis (DC 6523) and granulomatous rhinitis (DC 6524) have their own criteria. The allergic rhinitis guide covers those ratings in full.

The allergic rhinitis trap

The trap shows up when a veteran with chronic sinusitis gets evaluated by a C&P examiner who characterizes the condition as allergic rhinitis rather than chronic sinusitis. The diagnostic shift on paper moves the case from a four-tier ladder topping out at 50% to a two-tier ladder topping out at 30%.

I want to be careful here. Some veterans genuinely have allergic rhinitis and not chronic sinusitis, and DC 6522 is the right code for them. The clinical distinction matters. Allergic rhinitis is an allergy-driven condition of the nasal passages. Chronic rhinosinusitis is inflammation of the nose and sinuses lasting 12 weeks or longer, the definition VA's 2022 rating proposal takes from the otolaryngology practice guideline. The symptoms overlap, a veteran can have both, and imaging findings on CT (mucosal thickening, sinus opacification, polyps) can help sort out which diagnosis fits.

Here is what I'd watch for if I were filing or appealing.

• Has the C&P examiner explicitly diagnosed allergic rhinitis as the primary condition?
• Is there CT or X-ray imaging documenting actual sinus involvement (mucosal thickening, opacification, polyps)?
• Is there a history of bacterial sinus infections requiring antibiotic treatment?
• Has an ENT specialist evaluated the condition and offered a diagnosis?

If the answer to any of those points toward chronic sinusitis rather than pure allergic rhinitis, the DC 6510 to 6514 codes should be considered. The Board does look at this when it's raised, and the higher rating ladder is sometimes available with the right diagnostic clarification.

Can you be rated for both sinusitis and rhinitis?

Yes, when both conditions are diagnosed and their symptoms can be told apart. The rule in 38 CFR § 4.96(a) that bars combining certain respiratory ratings covers DCs 6600 through 6817 and 6822 through 6847 (the lung and airway codes, sleep apnea included), not the sinusitis or rhinitis codes. The limit that still applies is 38 CFR § 4.14: VA cannot rate the same symptom twice under two diagnoses.

Sinusitis secondary conditions: sleep apnea, migraines and asthma

Sinusitis filed in isolation often under-represents the overall picture. Under 38 CFR § 3.310, a condition that service-connected sinusitis caused, or aggravated, can be service connected as secondary. The Board section below lists the conditions most often claimed secondary to sinusitis at the Board; sleep apnea leads, followed by migraines.

Sleep apnea secondary to sinusitis

Sleep apnea is the condition veterans most often claim secondary to sinusitis at the Board. The medical support is real but specific. A 2026 systematic review and meta-analysis (Zhai, Sleep and Biological Rhythms) found that people with chronic rhinosinusitis had a higher risk of obstructive sleep apnea, and its genetic analysis supported chronic rhinosinusitis as a cause of sleep apnea rather than the reverse. A population finding is not proof for one veteran, so the claim still needs a sleep apnea opinion that explains how your nasal and sinus disease caused or worsened your sleep apnea, and that addresses weight, age and other causes. The respiratory rule in § 4.96(a) bars combining sleep apnea with the other codes in its group, such as asthma (DC 6602), but sinusitis is outside that group, so a sinusitis rating and a sleep apnea rating can combine.

Migraines secondary to sinusitis

Headache is part of the sinusitis criteria themselves, and that is where this chain needs care. The medical literature is more cautious than many claim guides. A 2024 review of headaches from nose and sinus disease (Marmura, Neurologic Clinics) concluded that most chronic and recurring headaches, especially those with migraine features, are not caused by sinus disease. A 2004 study (Schreiber, Archives of Internal Medicine) found that 88 percent of patients with a history of "sinus" headache met criteria for migraine-type headache. Migraine is still common in people with chronic rhinosinusitis, and a 2023 study (Derbarsegian, Laryngoscope) found that comorbid migraine went with worse quality of life.

For a claim, that means two things. First, an examiner may conclude your headaches are migraines unrelated to your sinuses, so a migraine secondary claim needs an opinion that explains, for your history, how the sinus disease caused the migraines or made them worse than they would otherwise be. Second, keep a log that separates sinus flare headaches from prostrating migraine attacks, because VA rates them differently. In decision 24002763 the VA examiner recorded the veteran's sinus flare headaches as a "separate issue" from his migraines, and the Board rated each condition on its own.

DC 8100 (migraine) rates as follows.

• 0%: less frequent attacks
• 10%: characteristic prostrating attacks averaging one in two months over the last several months
• 30%: characteristic prostrating attacks occurring on average once a month over the last several months
• 50%: very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability

A 50 percent migraine rating combined with a 30 percent sinusitis rating comes to 65, which rounds to 70. That is a very different compensation picture than sinusitis alone.

Asthma and other respiratory conditions

Asthma, rhinitis and sinusitis are the three chronic diseases listed together in § 3.320, and the 2025 adult sinusitis practice guideline (Payne, Otolaryngology-Head and Neck Surgery) names asthma among the chronic conditions that change how chronic rhinosinusitis is managed. COPD shares some respiratory rating logic, though the service-connection lane may differ, and § 4.96(a) bars combining asthma (DC 6602) and COPD (DC 6604) ratings with each other.

The secondary claim should be specific. "Sinusitis causes everything" is weak. "Service-connected chronic sinusitis has worsened my sleep apnea, as my ENT and sleep physician explain" is the kind of pathway a rater can evaluate. A secondary condition pathways from sinusitis review and respiratory C&P exam prep can help sort which downstream conditions belong in the claim package now and which need more treatment evidence first.

The sinusitis C&P exam and your flare records

The rating turns on episode count, and episode count turns on clinical notes. For each flare, the useful record includes date, sinus pain or pressure, headache, purulent discharge, crusting, fever if present, treatment given, antibiotic course if prescribed and how long it lasted, and whether bed rest was medically ordered.

The documentation gap I see in the decisions I read is consistent. Veterans report symptoms in their lay statements. They describe the pain, the pressure, the discharge, the headaches. What's often missing is the clinical record that ties those symptom complaints to a specific date, a specific provider visit, and either a specific antibiotic course or a specific bed-rest order. The Board doesn't infer episode counts. It counts what's documented, and it weighs your own account with it.

Decision 24002763 shows both sides. The Board denied any compensable rating for the period before June 24, 2019, because the VA exam and treatment records from that time did not show enough episodes, and the VA treatment records held no complaints of drainage or sinus tenderness. From June 24, 2019, it granted 30 percent under DC 6513 on the more-than-six non-incapacitating episodes route, relying on the veteran's statement describing "flare ups 7-8 times a year" with sinus pain, nasal crusting and headaches, and a private evaluation that applied the criteria, even though a later VA exam recorded no episodes in the prior 12 months.

Bring your treatment records, your antibiotic history and your own log to the exam. Use an evidence checklist for incapacitating-episode documentation and track episode frequency and symptoms so the file has dates instead of estimates.

Proposed VA sinusitis rating changes

In February 2022 VA proposed rewriting the ear, nose, throat and respiratory chapters of the rating schedule ("Schedule for Rating Disabilities," 87 FR 8474, February 15, 2022). For sinusitis, the proposal would drop incapacitating episodes and rate on how long antibiotic treatment lasted.

• 50%: 12 weeks or more of antibiotics in the past 12 months and no response to sinus surgery
• 30%: 12 weeks or more of antibiotics in the past 12 months
• 10%: at least four but less than 12 weeks of antibiotics in the past 12 months
• 0%: less than four weeks of antibiotics in the past 12 months

It would also move the codes to DCs 6222 through 6226 under the name rhinosinusitis, compensate only chronic and recurrent acute rhinosinusitis, and tell raters to rate allergic or nonallergic rhinitis under the rhinosinusitis formula when one of those forms of rhinosinusitis is present.

Status. As of early October 2026 VA has not published a final rule. The September 2024 supplemental notice on the same rulemaking (89 FR 74162) only proposed adding constrictive bronchiolitis to the respiratory chapter. Until a final rule takes effect, the current § 4.97 formula on this page is the rule VA and the Board apply. Under 38 CFR § 3.951(a), a change to the rating schedule is not grounds to reduce a rating already in effect unless the condition has actually improved.

Why VA denies sinusitis claims

Sinusitis claims do a little better at the Board than the average claim. Across 10,382 decided Board rulings on sinusitis from 2021 to 2026, 26.1% were granted, 33.1% denied and 40.9% remanded. That grant rate is 1.4 points above the Board-wide 24.7 percent, measured over 1,241,238 decided rulings.

When the Board denies sinusitis service connection, the most common reason by a wide margin is not the link to service. It is that the record does not show a current diagnosed disability. The patterns behind that, and behind the other denials, repeat.

No current diagnosis. Service records show sinus infections or congestion, but no clinician has diagnosed chronic sinusitis now, or the record shows only an acute infection that resolved. A single isolated episode is not a chronic disability.

Nothing in service. The in-service medical records are silent on sinus complaints, there is no presumptive lane, and the first complaint comes years after discharge with no account of what happened in between.

A conclusory nexus opinion. The opinion says "not related to military service" without explanation, or a favorable letter states a conclusion without reasoning, so the Board gives it little weight.

Symptoms tied to something else. The examiner attributes the symptoms to allergies, smoking or nasal anatomy, or rates the condition as allergic rhinitis instead.

Vague lay statements. "I have sinus problems sometimes" doesn't show episode frequency, treatment or functional impact. Specific descriptions with dates, symptoms and treatment do.

The Board grants when the in-service exposure or event is clearly documented (covered Southwest Asia or post-9/11 service for presumptive cases, in-service sinus complaints with treatment), when treatment records span multiple years after service, when lay statements describe specific episodes, and when the C&P examination addresses the in-service connection or is rebutted by a reasoned private opinion.

When the Board sends a sinusitis claim back instead of deciding it, the most common reason is an inadequate VA exam or medical opinion, ahead of records VA still had to get. The Board section below shows how often each denial and remand reason came up, and what happened after a remand.

What I Can't Tell You From This Data

There are real limits on what 10,382 decided Board rulings on sinusitis can teach you about your specific claim.

I can't tell you whether your individual exposure history qualifies under the PACT Act presumption. The list of covered locations and dates is specific. The full statutory list at 38 U.S.C. § 1119 and the regulatory implementation at 38 CFR § 3.320 are where the answer lives. VA may consider your entry in an exposure tracking system such as the Individual Longitudinal Exposure Record, and if that record is silent, the totality of your service (38 U.S.C. § 1119(a)), but your deployment records are still the safest proof.

I can't tell you whether your specific symptom pattern clears the "incapacitating episode" definition. That depends on what's in your treatment records, not only what's in your lay statement.

I can't tell you whether your case should be coded under DC 6510 to 6514 (chronic sinusitis) or DC 6522 (allergic rhinitis). That's a clinical question that an ENT specialist or a careful C&P examination should answer, not a question that aggregate data can resolve.

What the data can tell you is the structural shape of these claims at the Board. Presumptive claims go better than direct ones. A file with a medical opinion the Board can rely on wins far more often than one without. Remand is the most common outcome. The allergic rhinitis trap exists.

What it can't tell you is which side of those distributions your case will land on.

Questions veterans ask about sinusitis

Is chronic sinusitis presumptive under the PACT Act?

Yes. Chronic sinusitis is on the PACT Act list in 38 U.S.C. § 1120, and VA's 38 CFR § 3.320 lists sinusitis, including rhinosinusitis. If you served in a covered location, such as Iraq, Kuwait or Saudi Arabia from August 2, 1990, or Afghanistan, Syria or Djibouti from September 2001, you need a current diagnosis but not a nexus letter.

What is the highest VA rating for sinusitis?

Fifty percent. It requires radical sinus surgery with chronic osteomyelitis, or near-constant sinusitis with headaches, pain, tenderness, and purulent discharge or crusting after repeated surgeries. Without surgery, the highest sinusitis rating is 30 percent.

What counts as an incapacitating episode of sinusitis?

An episode that requires bed rest and treatment by a physician, under the note to 38 CFR § 4.97. Staying home and treating yourself does not count. More than six non-incapacitating episodes a year with headaches, pain, and purulent discharge or crusting can still support 30 percent.

Can you get a VA rating for both sinusitis and rhinitis?

Yes, if both are diagnosed and their symptoms can be told apart. Sinusitis is rated under DCs 6510 to 6514 and allergic rhinitis under DC 6522, and the respiratory rule against combining certain codes does not cover them. VA still cannot rate the same symptom twice (38 CFR § 4.14).

Can sleep apnea be secondary to sinusitis?

It can. Sleep apnea is the condition most often claimed secondary to sinusitis at the Board, and a 2026 meta-analysis found chronic rhinosinusitis raises the risk of obstructive sleep apnea. You still need a medical opinion that explains how your sinus disease caused or worsened your sleep apnea in your case.

Do I need a nexus letter for sinusitis?

Not if you qualify for the PACT Act presumption. If you do not, a nexus letter is usually the deciding evidence: it has to tie your current chronic sinusitis to something in service, explain why, and deal with other causes such as allergies, smoking or nasal anatomy.

Bottom Line

Sinusitis is rated under 38 CFR § 4.97 with a ladder running 0%, 10%, 30%, and 50%, and 50 percent is the formula's ceiling. Chronic sinusitis is a presumptive condition under the PACT Act and 38 CFR § 3.320 for veterans with qualifying Southwest Asia or post-9/11 service, and in the Board's rulings, sinusitis claims that raised a presumption were granted more often than direct ones. The "incapacitating episode" definition under § 4.97 requires bed rest and treatment by a physician, and that documentation threshold is where many 30% claims either earn the higher tier or fall back to 10%; the non-incapacitating route through more than six documented episodes a year is the other road to 30%. Diagnostic Code 6522 (allergic rhinitis) sits next to chronic sinusitis in the schedule but tops out lower, and the clinical line between the two is where some of the rating math gets lost. The secondary chain through sleep apnea is the one veterans claim most and has medical support; the chain through migraine needs a careful opinion, because much recurring "sinus" headache turns out to be migraine on its own. What earns the Board's reliance on a medical opinion is its reasoning, not the credentials of the writer. For veterans with qualifying PACT Act service, filing this claim under the right presumptive lane is the single biggest lever on the outcome. For veterans on the direct path, the nexus letter is the case. For veterans already rated at 10%, the path to 30% usually runs through documenting more episodes with provider notes, not through new medical opinions.

Sinusitis connects most often to sleep apnea, migraines, allergic rhinitis, asthma, Gulf War Illness, and COPD. Veterans with qualifying Southwest Asia or post-9/11 service should verify whether they are using the presumptive lane before filing as a direct claim.

Methodology and Limitations

• Data source: Statistics in this post are drawn from Claim Raven's read of 511,036 Board decisions from 2021 to 2026, which contain 1,378,030 rulings, including 11,410 rulings on sinusitis (10,382 with decided outcomes). Rating criteria are from 38 CFR § 4.97. Presumptive service connection rules are drawn from 38 U.S.C. §§ 1119 and 1120 (PACT Act) and 38 CFR § 3.320. Secondary connection mechanics are from 38 CFR § 3.310, the combined ratings example from § 4.25, and the respiratory combination rule from § 4.96(a). The proposed rating changes are from 87 FR 8474 (February 15, 2022) and 89 FR 74162 (September 12, 2024). Compensation figures are the VA disability rates effective December 1, 2025 (the 2026 rates) for a veteran with no dependents. The maxillary sinusitis count is from VA's Annual Benefits Report for fiscal year 2025.
• Medical sources: Zhai and colleagues, "Association between chronic rhinosinusitis and obstructive sleep apnea," Sleep and Biological Rhythms (2026); Marmura, "Headaches due to Nasal and Paranasal Sinus Disease," Neurologic Clinics (2024); Schreiber and colleagues, "Prevalence of migraine in patients with a history of self-reported or physician-diagnosed 'sinus' headache," Archives of Internal Medicine (2004); Derbarsegian and colleagues, "The Burden of Migraine on Quality of Life in Chronic Rhinosinusitis," Laryngoscope (2023); Payne and colleagues, "Executive Summary of the Clinical Practice Guideline on Adult Sinusitis Update," Otolaryngology-Head and Neck Surgery (2025).
• Board snapshot: Across 10,382 decided Board rulings on sinusitis from 2021 to 2026, 26.1% were granted (including partial grants and mixed outcomes), 33.1% denied and 40.9% remanded. Dismissed, withdrawn and moot rulings are excluded. These are appealed claims, not your personal odds.
• Classification approach: Rulings are counted as sinusitis based on how the Board's order names the condition. Claim theories, medical opinion findings, denial and remand reasons, and secondary pairs are shown in the Board section below rather than typed into the text. Medical opinion findings record what the Board credited, not grades of evidence quality. Evidence figures are associations, not causes.
• Limitations:
• Rulings that raised a presumption are counted where a presumption was raised in the Board decision. Not every veteran with PACT Act-qualifying service files under that lane, and some who file under it may be classified differently in the appellate disposition.
• The data does not record which rating tier a grant landed on, so no tier distribution is reported.
• The allergic rhinitis vs chronic sinusitis distinction is a clinical question. The allergic rhinitis rulings in my data are not all "mistakes." Some veterans genuinely have allergic rhinitis as the primary diagnosis.
• The "incapacitating episode" threshold reflects the regulatory text at § 4.97. Application varies across raters and examiners. Some treatment records that should qualify under that definition don't get coded that way at the rating level.
• The secondary chains to sleep apnea, migraine and other conditions reflect the medical studies cited above. Individual cases vary in how the secondary opinion holds up.
• Cases that made it to the BVA are not representative of all sinusitis claims. Many sinusitis claims are granted at the regional office or never appealed, and they don't appear in this dataset.
• These observations reflect patterns from BVA decisions. They are not predictions of individual outcomes.
