Nondisp longitud fx unsp patella, 7thK

This code signifies a fracture of the kneecap that runs lengthwise, has not shifted out of place, and is currently in a healing phase where the bone fragments have failed to unite after a previous treatment. The fracture is closed, meaning the skin remains intact over the injury site.

This code is appropriate for follow-up encounters for patients with a previously diagnosed nondisplaced longitudinal patellar fracture that is now complicated by nonunion. This would include situations where the patient is undergoing continued management, such as further imaging, physical therapy, or consideration for surgical intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and "subsequent encounter" for a closed fracture.
• Verify the fracture is specifically "longitudinal" and "nondisplaced" to avoid miscoding.
• Do not use for initial encounters or for fractures that are healing normally.
