Fx condylar process of mandible, unspecified side, 7thK

This code signifies a fracture of the condylar process of the mandible, where the specific side (left or right) is not documented. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase of the fracture, and "nonunion" specifies that the fracture has failed to heal properly after the expected time frame.

Use this code for follow-up visits when a patient with a previously diagnosed condylar process fracture of unknown laterality presents with evidence of nonunion. Documentation should clearly state "nonunion" or "failed healing" of the condylar fracture and indicate it's a subsequent encounter for care.

• Ensure documentation explicitly states "nonunion" to differentiate from routine healing (malunion or delayed union).
• Verify laterality is truly unspecified; if left or right is documented, a more specific code should be used.
• This code requires an external cause code (V00-Y99) to describe the circumstances of the injury, if known.
