Nondisp osteochon fx r patella, 7thR

This code describes a previously sustained, non-displaced osteochondral fracture of the right kneecap that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has now healed incorrectly. Malunion indicates that the bone fragments have united, but in an unsatisfactory position or alignment, potentially leading to functional impairment or pain. This is a subsequent encounter, meaning the patient is receiving follow-up care for the complications of the healing process.

Use this code for patients presenting for ongoing management of a malunited, non-displaced osteochondral fracture of the right patella, where the original injury was a severe open fracture. This would apply during clinic visits for assessment of function, pain management, or planning for corrective surgery related to the malunion. It is appropriate when the initial healing phase is complete, but the outcome is suboptimal.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the original fracture was an open fracture, type IIIA, IIIB, or IIIC, as this is a specific requirement.
• Do not use for initial treatment or for nonunion; a different code would be required for those scenarios.
