Diagnostic Code 9901 · 38 CFR §4.150
Complete loss of the mandible (lower jaw) between the angles is a catastrophic injury typically resulting from combat trauma such as blast injuries, gunshot wounds, or severe vehicle accidents during military service. This condition results in total inability to chew, significant difficulty with speech, severe facial disfigurement, and dependency on liquid or tube-fed nutrition. Reconstructive surgery may partially restore appearance but rarely fully restores function. The VA assigns a mandatory 100 percent rating for this condition, and it commonly qualifies for Special Monthly Compensation based on the need for aid and attendance or loss of use.
| Rating | Criteria |
|---|---|
| 100% | Complete loss of the mandible between the angles. This is a single-level rating — every veteran with this condition receives 100%. It reflects the catastrophic functional and cosmetic impact of total lower jaw loss. |
Surgical and trauma records documenting the injury and extent of mandible loss are essential. Service treatment records establishing the in-service event are needed. Post-surgical records and any reconstructive surgery documentation should be included. Functional assessments showing the impact on eating, speaking, and daily activities support additional benefits like Special Monthly Compensation.
Almost always yes. Complete loss of the mandible typically qualifies for Special Monthly Compensation at the aid and attendance level due to severe functional limitations with eating and communication. Talk to your VSO about which SMC categories apply to your situation.
