Chronic Osteomyelitis of Mandible

DC 9900Dental/Oral38 CFR 4.150, DC 9900

A chronic bone infection of the mandible (lower jaw) that causes pain, swelling, drainage, and progressive bone destruction. This condition often results from dental infections, jaw trauma, or surgery during military service. The VA rates it based on the severity of infection, treatment needs, and resulting bone damage.

How the VA rates this condition

The VA rates this condition based on the type and intensity of treatment you require. Higher ratings correspond to more aggressive treatment regimens, such as daily medication, insulin dependence, or the need for ongoing medical management.

Rating range

0% – 50%

Rating levels

Rating criteria are defined in 38 CFR 4.150, DC 9900. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

Your chronic osteomyelitis is severe with persistent infection despite treatment, significant mandibular bone destruction requiring surgical debridement, or pathologic fractures.

What the VA looks for

Persistent infection despite aggressive antibiotic therapy
Surgical debridement or sequestrectomy performed
Pathologic fracture of mandible documented
Significant bone loss on CT imaging
Severe dietary restrictions and speech impairment

Common Pitfalls

⚠Not documenting the chronicity of the infection — a single episode of osteomyelitis is different from a chronic condition. Keep records of every recurrence, antibiotic course, and surgical intervention to show the ongoing nature of the disease.
⚠Not connecting the osteomyelitis to in-service dental trauma or treatment — jaw infections can develop years after dental procedures, extractions, or jaw fractures sustained during service. A nexus opinion is critical.
⚠Not claiming secondary tooth loss — chronic osteomyelitis frequently causes loss of teeth in the affected area, which may qualify for a separate dental rating under DC 9913.
⚠Not documenting the impact on eating and nutrition — chronic jaw infection and bone loss make chewing painful and difficult, leading to weight loss and nutritional deficiencies that strengthen the overall disability picture.
