  • Note: An incapacitating episode of sinusitis means one that requires bed rest and treatment by a physician.

Chronic Maxillary Sinusitis (VA Diagnostic Code 6513)

Respiratory System · 38 CFR § 4.97

Understanding This Condition

Chronic maxillary sinusitis is a long-term inflammation of the maxillary sinuses (the sinus cavities located in the cheekbones, behind the face). The VA rates this condition under Diagnostic Code 6513, using the General Rating Formula for Sinusitis that applies to Diagnostic Codes 6510 through 6514.

When evaluating sinusitis, the VA distinguishes between two types of flare-ups:

  • Incapacitating episodes — episodes that require bed rest and treatment by a physician.
  • Non-incapacitating episodes — flare-ups characterized by headaches, pain, and purulent discharge or crusting that do not require bed rest.

Understanding which type of episode you experience, and how often, is central to how this condition is rated.

Available Rating Levels

The VA assigns one of the following disability ratings based on the frequency and severity of your symptoms:

50% Rating

Assigned following radical surgery with chronic osteomyelitis, or near-constant sinusitis characterized by headaches, pain and tenderness of the affected sinus, and purulent discharge or crusting after repeated surgeries.

30% Rating

Assigned for three or more incapacitating episodes per year of sinusitis requiring prolonged (lasting four to six weeks) antibiotic treatment, or more than six non-incapacitating episodes per year characterized by headaches, pain, and purulent discharge or crusting.

10% Rating

Assigned for one or two incapacitating episodes per year of sinusitis 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.

0% Rating

Assigned when the condition is detected by X-ray only.

What the VA Looks For

When rating chronic maxillary sinusitis, the VA focuses on:

  • The number of incapacitating episodes per year — episodes requiring bed rest and treatment by a physician.
  • Whether episodes require prolonged antibiotic treatment lasting four to six weeks.
  • The number of non-incapacitating episodes per year — flare-ups with headaches, pain, and purulent discharge or crusting.
  • Specific symptoms, including headaches, pain and tenderness of the affected sinus, and purulent discharge or crusting.
  • Surgical history, including radical surgery, repeated surgeries, and the presence of chronic osteomyelitis.
  • X-ray findings, particularly where the condition is detected by X-ray only.

This information is based on the VA General Rating Formula for Sinusitis (Diagnostic Codes 6510 through 6514) under 38 CFR § 4.97. Individual ratings depend on the specific medical evidence in each case.

These criteria are a rendering of § 4.97, diagnostic code 6513. The official version is the one that governs your rating.

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 6513 and attach the evidence for the level you are asking for. Other Respiratory System codes may cover your secondary conditions.
