Unsp fx r low leg, subs for opn fx type 3A/B/C w delay heal

This code signifies a fracture of the right lower leg (tibia, fibula, or both) where the specific bone involved is not documented. It is used when the patient is receiving follow-up care for an open fracture that initially broke through the skin, with significant soft tissue damage (Type IIIA, IIIB, or IIIC), and the healing process is taking longer than expected.

Apply this code for subsequent encounters when a patient with a previously diagnosed, unspecified open fracture of the right lower leg (Gustilo-Anderson Type IIIA, IIIB, or IIIC) is presenting for ongoing management due to delayed union or nonunion. This would include scenarios such as follow-up appointments for wound care, hardware adjustments, or assessment of bone healing progress when the fracture is not healing at the anticipated rate.

• Ensure documentation clearly states "unspecified" lower leg fracture and "delayed healing" for an open fracture Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters only; do not use for the initial treatment of the fracture.
• Verify laterality (right lower leg) is explicitly documented.
