Stress fracture, left tibia, subs for fx w routn heal

This code signifies a stress fracture affecting the left tibia that is currently in a healing phase, specifically a subsequent encounter where the healing is progressing routinely. A stress fracture is a small crack in a bone, often caused by repetitive stress or overuse, rather than a single traumatic event.

Apply this code when a patient presents for follow-up care of a previously diagnosed stress fracture of the left tibia, and the provider's documentation indicates routine healing. This code is appropriate for subsequent visits after the initial treatment, such as cast changes, physical therapy evaluations, or follow-up imaging to assess healing progress. Documentation should clearly state "stress fracture," "left tibia," and indicate "routine healing" or similar positive progress.

• Ensure the documentation specifies "left tibia" and not a different anatomical site or laterality.
• Distinguish from initial encounters (A) or encounters for delayed/nonunion healing (G, K, P, S).
• Verify that the encounter is indeed "subsequent" and that healing is progressing as expected, not complicated.
