Nondisp osteochon fx r patella, subs for clos fx w nonunion

This code signifies a fracture involving both the bone and cartilage of the right kneecap that is not displaced. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and a nonunion (failure of the bone to heal) has been identified, with the fracture remaining closed.

Use this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced osteochondral fracture of the right patella. This applies when imaging or clinical assessment confirms that the fracture has not healed properly (nonunion) and the skin over the fracture site remains intact. It is appropriate for ongoing management, such as preparing for revision surgery or continued conservative treatment for the nonunion.

• Ensure documentation clearly states "right patella" and "nondisplaced osteochondral fracture."
• Verify that the encounter is "subsequent" and that "nonunion" of a "closed fracture" is explicitly documented.
• Do not use for initial encounters or if the fracture is displaced, open, or has healed.
