Nondisp osteochon fx unsp patella, 7thM

This code describes a situation where a patient has a patellar fracture that involves both bone and cartilage, but the fragments are still in their normal anatomical position. This specific code is used when the patient is receiving follow-up care for an initial open fracture (where the skin was broken) that has not healed properly.

This code is appropriate for documenting subsequent encounters for patients with a previously treated open patellar osteochondral fracture that has failed to unite. It would be used when the patient presents for ongoing management, such as cast changes, physical therapy, or evaluation for further surgical intervention due to the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "osteochondral" for the patella.
• Verify that the initial injury was an "open fracture type I or II" and that the current encounter is for "nonunion."
• Do not use this code for initial encounters or for closed fractures.
