Fracture of alveolus of mandible, unspecified side, 7thK

This code signifies a fracture of the alveolar process of the mandible, where the specific side (left or right) is not documented. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care or treatment related to this unhealed fracture.

Apply this code for patients presenting for ongoing management of a mandibular alveolar fracture that has not united. Documentation should clearly indicate a nonunion and that this is not the initial treatment encounter. This code is appropriate when the medical record does not specify the affected side of the mandible.

• Ensure documentation explicitly states "nonunion" and "subsequent encounter" to support code assignment.
• Distinguish from malunion (S02.670P) or routine healing (S02.670D) of a mandibular alveolar fracture.
• If the side of the mandible is specified (left or right), use the more specific codes S02.671K or S02.672K, respectively.
