Nondisp intartic fx unsp calcaneus, subs for fx w malunion

This code signifies a follow-up encounter for a fracture within the joint surface of the heel bone (calcaneus) that was not initially displaced. The key characteristic for this specific code is that the fracture has healed in an imperfect alignment, known as a malunion.

Use this code when a patient presents for ongoing management, evaluation, or treatment of a previously sustained intraarticular calcaneal fracture that has healed with malunion. This applies to situations such as physical therapy for residual pain or limited range of motion due to the malunion, or surgical planning for corrective osteotomy.

• Ensure documentation clearly states "malunion" as the healing outcome for the calcaneal fracture.
• Verify the fracture is specifically "intraarticular" and "nondisplaced" from the initial injury.
• This "P" seventh character indicates a subsequent encounter for a fracture with malunion, not an initial treatment or routine healing.
