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

This code signifies a malunion of a previously open Type I or II fracture of an unspecified radius, where the bone has healed in a bent or angulated position. This indicates a complication of the initial fracture healing process, requiring ongoing medical management.

Apply this code for patients presenting with a bent radius due to a malunited open fracture (Type I or II) that has been previously treated. This is appropriate for follow-up encounters after the initial fracture care, where the malunion is being addressed or monitored.

• Ensure documentation clearly specifies "malunion" and "bent bone" of the radius.
• Verify the original fracture was an open Type I or II to align with the code's specificity.
• This is a subsequent encounter code; do not use for the initial treatment of the fracture.
