These notes are part of the regulation. They change how the levels above are applied.

  • Note (1): For VA compensation purposes, diagnostic imaging studies include, but are not limited to, conventional radiography (X-ray), computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), radionuclide bone scanning, or ultrasonography
  • Note (2): Separately evaluate loss of vocal articulation, loss of smell, loss of taste, neurological impairment, respiratory dysfunction, and other impairments under the appropriate diagnostic code and combine under § 4.25 for each separately rated condition

Loss of the Coronoid Process — VA Disability Rating (Diagnostic Code 9909)

Dental and Oral Conditions · 38 CFR § 4.150

Understanding This Condition

The coronoid process is a bony projection of the lower jaw (mandible). Diagnostic Code 9909 addresses the loss of the coronoid process and is rated by the VA under § 4.150, which covers dental and oral conditions.

The VA assigns a disability rating based on whether the loss affects one side or both sides of the jaw.

Available Rating Levels

RatingCriteria
20%Bilateral (both sides)
10%Unilateral (one side)

What the VA Looks For

  • Whether the loss is unilateral or bilateral. This is the primary factor that distinguishes the 10% and 20% rating levels.

  • Diagnostic imaging. For VA compensation purposes, diagnostic imaging studies include, but are not limited to, conventional radiography (X-ray), computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), radionuclide bone scanning, or ultrasonography.

  • Related impairments rated separately. The VA separately evaluates loss of vocal articulation, loss of smell, loss of taste, neurological impairment, respiratory dysfunction, and other impairments under the appropriate diagnostic code, and combines them under § 4.25 for each separately rated condition.

These criteria are a rendering of § 4.150, diagnostic code 9909. 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 9909 and attach the evidence for the level you are asking for. Other Dental and Oral Conditions codes may cover your secondary conditions.
