Stress fracture, left shoulder, subs for fx w malunion

This code signifies a stress fracture affecting the left shoulder, specifically when the patient is receiving follow-up care for a fracture that has healed improperly (malunion). A stress fracture is a small crack in a bone, often caused by repetitive stress or overuse, rather than a single traumatic injury. Malunion indicates that the bone has healed in an anatomically incorrect or deformed position.

Use this code for patients presenting for ongoing treatment, rehabilitation, or evaluation of a previously diagnosed left shoulder stress fracture that has resulted in malunion. Documentation should clearly state "subsequent encounter" and confirm the presence of a malunion of the stress fracture. This code is appropriate when the patient is no longer in the initial healing phase but requires continued management for the complication of malunion.

• Ensure documentation explicitly states "subsequent encounter" and "malunion" for the left shoulder stress fracture.
• Distinguish from initial encounters (initial healing phase) or nonunion (failure of bone to heal).
• Consider additional codes for any associated pain, functional limitations, or surgical interventions related to the malunion.
