Oth fracture of unsp patella, subs for clos fx w malunion

This code signifies a fracture of the kneecap, not otherwise specified as comminuted, transverse, or other specific types, that is currently in the healing phase. The fracture was initially closed (skin intact) and has healed incorrectly, resulting in a malunion.

Apply this code when documenting follow-up care for a patient whose unspecified patellar fracture, initially closed, has healed in an anatomically incorrect position. This is used for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and that the fracture was "closed" initially.
• Confirm this is a follow-up encounter, not the initial treatment or an active nonunion.
• Verify the fracture site is the patella and the specific type is not further defined.
