Fx unsp part of body of mandible, unspecified side, 7thK

This code signifies a nonunion of a fracture involving an unspecified portion of the mandible, with the specific side also not documented. Nonunion indicates that the bone has failed to heal completely after a previous fracture, and this encounter is for ongoing management of that nonunion.

Apply this code when a patient presents for follow-up care or treatment of a mandibular fracture that has failed to unite, and the medical record does not specify the exact anatomical location or side of the mandible involved. Documentation should clearly state "nonunion" of a mandibular fracture and indicate that this is a subsequent encounter.

• Ensure documentation explicitly states "nonunion" and that it's a subsequent encounter for the fracture.
• If the specific part of the mandible (e.g., condyle, body, angle) or the side (left/right) is documented, a more specific code within the S02.6 series should be used.
• This code should be sequenced after any acute conditions or complications being treated during the same encounter.
