Stress fracture, left fibula, subs for fx w delay heal

This code signifies a stress fracture affecting the left fibula that is currently undergoing treatment, but the healing process is not progressing as expected. It indicates a pathological fracture resulting from repetitive stress rather than acute trauma, with a documented delay in bone consolidation.

Apply this code when a patient presents for follow-up care of a previously diagnosed left fibular stress fracture that is exhibiting delayed healing. Documentation should clearly state "stress fracture," specify the "left fibula," and explicitly mention "delayed healing" or similar terminology indicating a prolonged recovery period.

• Ensure documentation specifies "stress fracture" as opposed to other fracture types; otherwise, a different M84 subcategory may be more appropriate.
• Verify the laterality (left fibula) is clearly documented.
• This "G" seventh character indicates subsequent encounter with delayed healing; do not use for initial treatment or routine healing.
