# DC 9901 - Mandible, loss of, complete, between angles

Rated under § 4.150. Body system: Dental and Oral Conditions.

## Rating criteria

| Rating | Criteria |
| --- | --- |
| 100% | Mandible, loss of, complete, between angles |

## Notes

- 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

# Complete Loss of the Mandible (Between the Angles) — VA Disability Rating (Diagnostic Code 9901)

## Understanding This Condition

The mandible is the lower jawbone. **Diagnostic Code 9901** addresses the *complete loss of the mandible between the angles* — meaning the loss of the central portion of the lower jaw between the two points (angles) where the jawbone curves upward toward the ears.

This condition falls under the VA's rating schedule for **Dental and Oral Conditions**, evaluated under **§ 4.150** of the Code of Federal Regulations.

## Available Rating Level

Under Diagnostic Code 9901, the VA provides a single rating level:

| Rating | Criteria |
|--------|----------|
| **100%** | Mandible, loss of, complete, between angles |

## What the VA Looks For

When evaluating this condition, the VA considers:

- **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.
