Fracture of subcondylar process of right mandible, 7thK

This code describes a fracture of the subcondylar process on the right side of the mandible that has failed to heal properly after an initial treatment. Nonunion indicates that the bone ends have not united and the healing process has ceased, requiring further intervention.

This code is used when a patient presents for ongoing management of a previously treated right mandibular subcondylar fracture that has been diagnosed with nonunion. Documentation should clearly state "nonunion" of the fracture and specify the right subcondylar process. This would typically be seen in follow-up visits after initial treatment, where healing complications are being addressed.

• Ensure documentation explicitly states "nonunion" and the specific anatomical site (subcondylar process) and laterality (right).
• Do not use this code for initial treatment of the fracture or for routine follow-up of a healing fracture without nonunion.
• A 7th character "K" indicates subsequent encounter for fracture with nonunion; verify the correct 7th character based on the encounter type.
