Nondisp commnt fx unsp patella, 7thR

This code describes a patellar fracture that is broken into multiple pieces (comminuted) but remains in its normal anatomical position (nondisplaced). It specifically indicates a subsequent encounter for an open fracture (where the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC) that has healed in a misaligned or deformed position (malunion).

This code is appropriate for follow-up visits where a patient is being managed for complications arising from a previously sustained, severe open comminuted patellar fracture that has healed with malunion. This could include assessment of pain, functional limitations, or planning for corrective surgery related to the malunion.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the patellar fracture.
• Verify that the original injury was an "open fracture type IIIA, IIIB, or IIIC" and that "malunion" is explicitly documented.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
