Stress fx, unsp tibia and fibula, subs for fx w routn heal

This code signifies a stress fracture affecting an unspecified bone of the lower leg (tibia or fibula) that is currently in the healing phase following initial treatment. It indicates that the patient is receiving follow-up care for a fracture that is progressing routinely without complications.

Use this code for patients presenting for subsequent visits related to a stress fracture of the tibia or fibula, where the fracture is healing as expected. Documentation should clearly state "stress fracture," specify the tibia or fibula (even if unspecified), and indicate "subsequent encounter" with "routine healing."

• Ensure documentation specifies "stress fracture" versus a traumatic fracture.
• Verify the encounter is for follow-up care, not initial treatment or a nonunion.
• Confirm "routine healing" is documented; otherwise, consider codes for delayed healing or nonunion.
