Unsp fx r patella, subs for opn fx type 3A/B/C w malunion

This code signifies a previously diagnosed, unspecified fracture of the right kneecap that is now being treated for a complication of malunion. The original fracture was an open fracture, specifically classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. Malunion means the fracture has healed in an incorrect or deformed position.

This code is appropriate when a patient presents for follow-up care, surgical correction, or management of a malunited right patellar fracture. The initial injury must have been an open fracture of a severe type (IIIA, IIIB, or IIIC). This code would be used for encounters after the initial treatment of the acute fracture.

• Ensure documentation clearly specifies "malunion" as the current complication.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC of the right patella.
• This code is for subsequent encounters, not the initial treatment of the acute fracture.
