Bent bone of unsp ulna, 7thR

This code signifies a malunion of a previously open fracture of the ulna, where the bone has healed in a bent or angulated position. The original fracture was severe, classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for this complication.

Use this code when documenting follow-up care for a patient whose ulna, previously fractured in a severe open injury (Type IIIA, IIIB, or IIIC), has healed with a noticeable angulation or deformity. This applies to situations where the malunion is being assessed, monitored, or treated in a subsequent visit after the initial fracture management.

• Ensure the documentation clearly states "malunion" and specifies the "bent bone" characteristic of the ulna.
• Verify that the original fracture was indeed an open fracture classified as Type IIIA, IIIB, or IIIC.
• Confirm this is a subsequent encounter for the malunion, not the initial treatment of the fracture or malunion.
