Bent bone of l ulna, subs for opn fx type I/2 w routn heal

This code signifies a deformity of the left ulna, specifically a bent bone, that occurred as a result of a previous open fracture. The original fracture was classified as Type I or II, indicating a relatively clean break with minimal soft tissue damage, and is currently healing routinely. This code is used during follow-up care after the initial treatment of the fracture.

This code is appropriate for documenting subsequent encounters for a patient with a left ulnar shaft deformity following an open fracture (Type I or II) that is progressing through an expected healing process. It would be used during routine follow-up appointments, cast changes, or physical therapy sessions where the primary focus is monitoring the healing of the previously sustained open fracture.

• Ensure documentation specifies "bent bone" or a similar deformity of the ulna, not just a healed fracture.
• Verify the original fracture was an open Type I or II and that healing is routine, not delayed or complicated.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
