Nondisp intartic fx l calcaneus, subs for fx w nonunion

This code signifies a fracture within the joint space of the left heel bone that has not shifted out of alignment. The patient is in a later stage of care, and the fracture is failing to heal properly, indicating a nonunion.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced intraarticular left calcaneal fracture is being treated for a confirmed nonunion. This includes situations where surgical intervention for nonunion is being planned or has already occurred during the subsequent encounter.

• Ensure documentation clearly states "nonunion" for the calcaneal fracture.
• Verify the fracture is specifically intraarticular and nondisplaced.
• Confirm the encounter is subsequent to the initial fracture treatment.
