Nondisp fx of ant pro of l calcaneus, subs for fx w nonunion

This code describes a situation where a patient has a fracture of the front part of the left heel bone that is not out of alignment. The fracture has failed to heal properly, and the patient is presenting for ongoing treatment related to this nonunion.

Use this code when documenting a patient visit for continued management of a previously diagnosed, nondisplaced anterior calcaneal process fracture of the left foot that has not united. This applies to encounters where the focus is on the nonunion, such as follow-up appointments, cast changes, or discussions about further intervention for the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for this specific fracture site.
• Verify laterality (left) and displacement status (nondisplaced) are accurately reflected in the medical record.
• Do not use for initial treatment of the fracture or for routine follow-up of a healing fracture without evidence of nonunion.
