Bent bone of unsp rad, subs for opn fx type I/2 w nonunion

This code signifies a bent bone deformity of the radius, where the specific location on the radius is not documented. It is used when the patient is receiving follow-up care for a previously sustained open fracture (Type I or II) that has failed to heal properly, resulting in a nonunion.

Apply this code for patients presenting with a bent radius deformity following an open fracture (Gustilo-Anderson Type I or II) that has not united. This is appropriate for subsequent encounters where the focus is on managing the nonunion and the associated deformity.

• Ensure documentation clearly states "bent bone" or a similar deformity of the radius.
• Verify the original injury was an open fracture, specifically Type I or II, and that nonunion is present.
• Confirm this is a subsequent encounter for ongoing treatment of the nonunion, not the initial injury.
