Nondisp commnt fx right patella, subs for clos fx w malunion

This code signifies a comminuted fracture of the right kneecap that is not displaced, meaning the bone fragments are still in their anatomical position. The patient is in a subsequent phase of care, and the fracture has healed incorrectly, resulting in a malunion. This indicates a complication of the healing process for a previously treated closed fracture.

Use this code when documenting follow-up care for a patient who sustained a right patella fracture that was initially closed and nondisplaced, but has now healed with a deformity or misalignment. This would apply to scenarios where the malunion is being evaluated, monitored, or treated, such as during physical therapy or surgical planning for corrective osteotomy.

• Ensure documentation clearly states "nondisplaced" and "comminuted" for the right patella fracture.
• Confirm the encounter is "subsequent" and that a "malunion" has been diagnosed as a complication of a "closed fracture."
• Do not use this code for initial treatment of the fracture or for nonunion (failure to heal).
