Unsp fx lower end of right ulna, init for opn fx type 3A/B/C

This code signifies an unspecified fracture located at the lower end of the right ulna. The "C" in the seventh character indicates that this is the initial encounter for an open fracture classified as Type IIIA, IIIB, or IIIC, meaning there is significant soft tissue damage and potential contamination.

This code is appropriate for the initial treatment of a patient presenting with an open fracture of the distal right ulna where the specific type of fracture (e.g., transverse, oblique) is not documented. It is specifically used when the Gustilo-Anderson classification for open fractures indicates a severe open injury (Type IIIA, IIIB, or IIIC).

• Ensure documentation clearly specifies the right ulna and an open fracture type IIIA, IIIB, or IIIC.
• Do not use this code if the fracture type (e.g., transverse, comminuted) is specified; a more specific code would then be appropriate.
• The "C" seventh character indicates initial treatment for the open fracture, regardless of subsequent procedures.
