Stress fracture, unsp site, subs for fx w malunion

This code signifies a stress fracture that has occurred at an unidentifiable anatomical location, and the patient is presenting for follow-up care related to a previous stress fracture that healed improperly (malunion). It indicates ongoing management of a previously diagnosed stress fracture with a documented complication of healing.

Apply this code when a patient is seen for continued treatment or evaluation of an unspecified stress fracture that has resulted in malunion. Documentation should clearly state a stress fracture, an unspecified site, and the current encounter addressing the malunion from a prior fracture. This is appropriate for subsequent visits after the initial treatment of the malunion has begun.

• Ensure documentation specifies "subsequent encounter" and "malunion" for a stress fracture.
• Do not use for initial treatment of a stress fracture or for nonunion; separate codes exist for those scenarios.
• Always review the medical record for a more specific anatomical site if available; "unspecified site" should only be used when no further detail is provided.
