Unsp fracture of unsp forearm, init for opn fx type I/2

This code signifies a fracture of the forearm where the specific bone (radius or ulna) and the exact location of the break are not documented. It indicates that the skin was broken, exposing the bone, and the injury is classified as an open fracture type I or II according to the Gustilo-Anderson classification. This is the initial encounter for this injury.

Use this code when the medical record clearly states an open forearm fracture (type I or II) but lacks specific details about which forearm bone is fractured or the precise location of the fracture. This is appropriate for the patient's first visit for treatment of this injury.

• Ensure the documentation explicitly states "unspecified forearm fracture" or lacks the detail to specify radius/ulna and location.
• Verify the open fracture type is documented as I or II; if not specified, default to unspecified open fracture.
• Confirm this is the initial encounter for the injury; subsequent encounters will use different seventh characters.
