Nondisp osteochon fx unsp patella, 7thN

This code signifies a follow-up visit for a patient who previously sustained a nondisplaced osteochondral fracture of an unspecified patella. The initial injury was an open fracture, specifically classified as Type IIIA, IIIB, or IIIC, and has since developed a nonunion, meaning the bone fragments have failed to heal together.

This code is appropriate for subsequent encounters where a patient is being managed for a patellar nonunion that originated from a severe open osteochondral fracture. This includes visits for ongoing treatment, monitoring, or evaluation of the nonunion after the initial injury and acute care have passed.

• Ensure documentation clearly states "subsequent encounter" and specifies the nonunion of an open fracture type IIIA, IIIB, or IIIC.
• Verify the fracture is specifically osteochondral and nondisplaced.
• Do not use for initial encounters or for fractures that have healed.
