Displ spiral fx shaft of l femr, subs for clos fx w malunion

This code describes a situation where a patient has a spiral fracture in the shaft of their left thigh bone that was initially displaced, but has since healed incorrectly, resulting in a malunion. This indicates a complication of the healing process where the bone fragments have joined in a deformed position.

Use this code for follow-up encounters where a previously treated displaced spiral fracture of the left femoral shaft is now being managed due to a confirmed malunion. This applies when the fracture itself is no longer acute, but the resulting deformity from improper healing is the focus of the encounter.

• Ensure documentation clearly states "malunion" and specifies the left femur and spiral fracture type.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
• Verify laterality (left) is accurately documented to avoid coding errors.
