Fracture of ramus of mandible, unspecified side, 7thK

This code describes a fracture of the ramus of the mandible that has failed to heal properly after initial treatment. "Nonunion" indicates that the bone fragments have not united and healing has ceased, requiring further intervention. This is a subsequent encounter, meaning the patient is receiving active treatment for the nonunion.

Apply this code when a patient presents for ongoing management of a previously treated ramus fracture that has developed nonunion. Documentation should clearly state "nonunion" of the mandibular ramus and indicate that this is not the initial treatment phase. This code is appropriate for follow-up visits, surgical interventions, or other treatments aimed at addressing the nonunion.

• Ensure documentation specifies "nonunion" and not just delayed healing or malunion.
• Verify the specific anatomical site (ramus of mandible) and laterality if known; this code is for unspecified side.
• Confirm the encounter type is "subsequent" for the fracture with nonunion, not initial or sequela.
