Unsp fx l forearm, subs for opn fx type I/2 w delay heal

This code signifies an open fracture of the left forearm, where the specific bone involved (radius, ulna, or both) is not documented. It indicates that the patient is in a subsequent phase of care for a Type I or II open fracture, and the healing process is taking longer than expected.

Apply this code when a patient presents for follow-up care of an open left forearm fracture, and the medical record indicates delayed healing for a Gustilo-Anderson Type I or II open injury. This is appropriate when the precise bone fractured within the forearm is not specified in the documentation.

• Ensure documentation clearly states "delayed healing" for the open fracture.
• Verify the encounter is for subsequent care, not the initial treatment.
• Confirm the open fracture type is documented as I or II; other types require different codes.
