Nondisp fx of body of left calcaneus, subs for fx w nonunion

This code describes a situation where the main part of the left heel bone (calcaneus) was broken, but the broken pieces did not shift out of alignment. The fracture, however, has not healed properly and is now considered a nonunion, and the patient is presenting for follow-up care related to this ongoing healing complication.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed nondisplaced fracture of the body of the left calcaneus that has failed to unite. This includes follow-up visits for ongoing management, evaluation of nonunion, or preparation for surgical intervention to address the nonunion.

• Ensure documentation clearly specifies "nonunion" as the healing complication.
• Verify the fracture location is the "body" of the calcaneus and on the "left" side.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
