Pathological fracture, left fibula, subs for fx w routn heal

This diagnosis code indicates a pathological fracture of the left fibula that is currently undergoing routine healing. A pathological fracture occurs due to a disease process weakening the bone, rather than from significant trauma. The "subsequent encounter" designation signifies that the patient is receiving follow-up care for the healing fracture.

Apply this code when a patient presents for ongoing management of a left fibular pathological fracture that is healing as expected. Documentation should clearly state "pathological fracture," specify the left fibula, and indicate routine healing during a follow-up visit. This code is appropriate for clinic visits, cast changes, or imaging reviews during the healing phase.

• Ensure documentation specifies "pathological" to differentiate from traumatic fractures.
• Verify the laterality (left) and bone (fibula) are explicitly stated in the medical record.
• The "D" seventh character is crucial for subsequent encounters with routine healing; do not use for initial care or delayed/nonunion healing.
