Unsp fx left femur, subs for opn fx type 3A/B/C w malunion

This code describes a situation where a patient has an unspecified fracture of their left femur that is currently being treated for a complication of healing. Specifically, the fracture was an open fracture of type IIIA, IIIB, or IIIC, and it has healed improperly, resulting in a malunion. This indicates ongoing care for the non-anatomic alignment of the bone segments.

Use this code when documenting follow-up care for a patient whose left femoral fracture, initially an open type IIIA, IIIB, or IIIC, has healed with a deformity or misalignment. This applies to encounters where the malunion itself is the focus of treatment, such as surgical correction, physical therapy, or monitoring. It signifies that the initial fracture treatment is complete, but a complication of healing is now being addressed.

• Ensure documentation clearly states "malunion" and specifies the left femur.
• Confirm the original fracture was an open type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; do not use for initial treatment of the fracture.
