Nondisp bimalleol fx r low leg, subs for clos fx w nonunion

This code signifies a fracture involving both the medial and lateral malleoli of the right ankle that remains in its anatomical position (nondisplaced). The patient is in a follow-up phase of treatment, and the fracture has failed to heal properly, indicating a nonunion.

This code is appropriate for documenting ongoing care for a right bimalleolar fracture where initial treatment has not resulted in bone healing. It is used when the patient presents for evaluation or management of the nonunion, such as for consideration of revision surgery or continued conservative management.

• Ensure documentation clearly states "right" lower leg and specifies "bimalleolar" involvement.
• Confirm the fracture is explicitly documented as "nondisplaced" and that "nonunion" is identified.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
