Bent bone of unsp ulna, init for opn fx type I/2

This code signifies a fracture of the ulna, specifically a "bent bone" type, where the exact location on the ulna is not specified. It indicates an open fracture, classified as either Type I or Type II, meaning there is a break in the skin communicating with the fracture site. This code is used for the initial treatment encounter of such an injury.

Apply this code when documenting the initial treatment for an open ulna fracture where the bone is described as bent, but the specific part of the ulna (e.g., shaft, distal end) is not detailed in the medical record. This is appropriate for open fractures of Gustilo-Anderson Type I or II.

• Ensure the documentation clearly states "bent bone" and an "open fracture type I or II" for the ulna.
• Verify this is the patient's initial encounter for this specific injury. Subsequent encounters will require a different seventh character.
• If the specific location on the ulna is documented (e.g., shaft, distal end), a more specific code should be chosen.
