Unsp fracture of left calcaneus, subs for fx w nonunion

This code describes a situation where a patient has a fracture of the left heel bone (calcaneus) that was not specified as displaced or non-displaced, and the fracture has failed to heal properly after initial treatment. This nonunion indicates that the bone fragments have not fused together, requiring further medical intervention.

This code is appropriate for documenting follow-up care for a patient with a previously diagnosed, unspecified left calcaneal fracture that has not united. It would be used when the patient presents for ongoing management, evaluation, or treatment of the nonunion, such as surgical intervention or prolonged immobilization.

• Requires an additional code to specify the underlying cause of the fracture (e.g., traumatic injury, stress fracture).
• Ensure documentation clearly states "nonunion" and specifies the left calcaneus.
• Distinguish from malunion, which implies healing in an incorrect anatomical position.
