Nondisp osteochon fx r patella, 7thN

This code describes a non-displaced fracture involving both cartilage and underlying bone of the right kneecap. It specifically indicates that the patient is in a later stage of care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly.

This code is appropriate for follow-up encounters where a patient is being treated for a right patellar osteochondral fracture that was initially an open fracture of a severe type, and the fracture has not united. This would include scenarios such as ongoing management of nonunion, planning for revision surgery, or monitoring the non-healing status.

• Ensure documentation clearly specifies "nonunion" for the subsequent encounter.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC.
• Confirm the fracture is of the right patella and is described as osteochondral and nondisplaced.
