Barton's fx unsp radius, init for opn fx type 3A/B/C

This code signifies a Barton's fracture, which is an intra-articular fracture of the distal radius with dorsal or volar displacement of the carpus. Specifically, it indicates an open fracture classified as type IIIA, IIIB, or IIIC, meaning there is significant soft tissue damage and potential for contamination, and it is the initial treatment encounter. The "unspecified radius" component means the laterality (left or right) of the fracture is not documented.

Apply this code when documentation confirms a Barton's fracture of the distal radius that is explicitly described as an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is appropriate for the initial visit where the fracture is diagnosed and treatment begins, and when the medical record does not specify whether the fracture occurred on the left or right arm.

• Ensure the documentation clearly specifies "open fracture" and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC).
• Only use this code for the initial encounter for treatment of the fracture. Subsequent care would require a different encounter character.
• Avoid this code if laterality (left or right radius) is documented; instead, use a more specific code.
