Bent bone of right ulna, subs for opn fx type I/2 w nonunion

This code signifies a bent or malformed right ulna that has failed to heal properly following an initial open fracture of either Type I or Type II. The "bent bone" aspect indicates a deformity in the bone's alignment, and "nonunion" confirms that the fracture fragments have not united after a sufficient healing period.

Use this code when documenting ongoing treatment for a patient whose right ulna open fracture (Type I or II) has resulted in a persistent nonunion with a noticeable angulation or bending of the bone. This applies to follow-up visits after the initial fracture care, where the nonunion and deformity are being addressed.

• Ensure documentation clearly specifies "nonunion" and a "bent bone" or similar deformity of the right ulna.
• Verify the original fracture was an "open fracture type I or II" to align with the code's specificity.
• This code is for subsequent encounters, meaning it should not be used for the initial fracture treatment.
