Oth fx shaft of rad, unsp arm, init for opn fx type 3A/B/C

This code signifies a fracture of the main part (shaft) of the radius bone in an unspecified arm, where the skin and soft tissues are significantly damaged, exposing the bone. This type of open fracture, classified as IIIA, IIIB, or IIIC, indicates high-energy trauma with extensive soft tissue loss, contamination, or neurovascular injury.

Apply this code when documenting an initial encounter for a patient presenting with a traumatic open fracture of the radial shaft, and the medical record clearly specifies that the Gustilo-Anderson classification is type IIIA, IIIB, or IIIC. This code is appropriate for the acute phase of treatment, including initial assessment, surgical repair, and stabilization.

• Ensure the documentation explicitly states "unspecified arm" and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) for the open fracture.
• Verify this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Do not use this code if the fracture is closed or if the open fracture type is not specified as IIIA, IIIB, or IIIC.
