Stress fracture, left shoulder, subs for fx w nonunion

This code signifies a stress fracture affecting the left shoulder, specifically when the fracture has failed to heal properly (nonunion) and the patient is receiving active treatment for this complication. A stress fracture is a small crack in a bone, often caused by repetitive stress or overuse.

Apply this code for patients presenting for follow-up care, surgical intervention, or other active management of a left shoulder stress fracture that has been diagnosed with nonunion. Documentation should clearly state "stress fracture," "left shoulder," and "nonunion," along with an indication that this is not the initial encounter for the fracture.

• Ensure documentation specifies "stress fracture" versus other types of fractures (e.g., pathological, traumatic).
• Verify laterality (left shoulder) is clearly documented.
• Confirm the "subsequent encounter" and "nonunion" status are explicitly stated or clearly implied by the treatment plan.
