Stress fracture, unsp shoulder, subs for fx w routn heal

This code signifies a stress fracture affecting an unspecified part of the shoulder, indicating a bone injury resulting from repetitive microtrauma rather than a single acute event. The "D" seventh character specifies that the patient is in the healing phase following initial treatment, and the fracture is progressing routinely without complications.

Apply this code for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed stress fracture of the shoulder. Documentation should confirm routine healing, such as stable imaging findings or clinical assessment indicating expected recovery progress. This code is appropriate when the patient is beyond the initial acute treatment phase but not yet fully healed.

• Ensure documentation clearly states "stress fracture" and specifies the shoulder as the affected site.
• The "D" seventh character is crucial for subsequent encounters with routine healing; do not use "A" (initial encounter) or "S" (sequela).
• If the specific bone within the shoulder (e.g., clavicle, scapula, humerus) is documented, a more specific code from the M84.31- subcategory should be used.
