Unsp fx shaft of left radius, init for opn fx type 3A/B/C

This code signifies an unspecified break in the main part (shaft) of the left forearm bone (radius) that has broken through the skin, indicating a severe open fracture. The "IIIA, IIIB, or IIIC" classification refers to the Gustilo-Anderson open fracture grading system, denoting significant soft tissue damage, contamination, or extensive periosteal stripping.

This code is appropriate for the initial treatment of a patient presenting with a left radial shaft fracture where the bone has penetrated the skin, and the specific type of open fracture (IIIA, IIIB, or IIIC) has been documented by the physician. It is used for the first encounter for this specific injury.

• Ensure physician documentation clearly specifies "unspecified fracture of shaft of left radius" and "open fracture type IIIA, IIIB, or IIIC."
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require different seventh characters.
• Do not use this code if the fracture site or type is more specifically documented (e.g., transverse, oblique, comminuted).
