Fracture of unspecified part of body of right mandible, 7thK

This code signifies a fracture of an unspecified portion of the right lower jawbone that has failed to heal properly after an initial treatment attempt. Nonunion indicates that the bone ends have not united and are not expected to unite without further intervention, such as surgery. This represents a complication of the original fracture.

Apply this code when a patient presents for ongoing management of a right mandibular fracture that has been previously treated but demonstrates evidence of nonunion. Documentation should clearly state "nonunion" and specify the right side of the mandible, even if the exact anatomical site (e.g., condyle, body) is not specified.

• Ensure documentation explicitly states "nonunion" and specifies the right mandible.
• This code requires a seventh character "K" for subsequent encounter with nonunion; do not use for initial treatment or routine follow-up without nonunion.
• Consider co-reporting with external cause codes (V, W, X, Y) if the cause of the original fracture is known and relevant for the encounter.
