Complete Loss of Mandible — VA Disability Rating (DC 9901)
Diagnostic Code 9901 · 38 CFR §4.150
What Is It?
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
| 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. |
Evidence Needed
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.
C&P Exam Tips
The examiner will evaluate the extent of bone loss and functional impact. Describe all functional limitations: inability to eat solid foods, speech difficulties, cosmetic impact, and any psychological effects of the disfigurement. If you require assistance with eating or daily activities, describe that need clearly, as it supports a Special Monthly Compensation claim.
How to File
File on VA Form 21-526EZ with DC 9901. This is typically a straightforward claim given the severity and objective nature of the condition. Submit surgical records, imaging, and service treatment records documenting the injury. Consider also filing for Special Monthly Compensation and for disfigurement under the skin rating criteria (DC 7800). A VSO experienced with severe injury claims is recommended.
Common Mistakes
Not filing for Special Monthly Compensation when the condition requires aid and attendance is a significant oversight. Not claiming disfigurement separately under DC 7800 (skin) misses additional compensation. Not filing for secondary conditions like depression or PTSD related to the severe injury and disfigurement leaves compensation on the table.
Frequently Asked Questions
Does this qualify for 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.
