Oth fx shaft of unsp ulna, 7thJ

This code signifies a fracture of the shaft of the ulna, where the specific location on the ulna is not documented. It is an open fracture, classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure. This particular code is used for subsequent encounters when the fracture is experiencing delayed healing.

This code is appropriate for follow-up visits where a patient with a previously diagnosed open ulnar shaft fracture (Type IIIA, IIIB, or IIIC) is presenting with evidence of delayed union or non-union. It would be used when the physician is assessing the progress of healing and determining further management for the delayed healing.

• Ensure documentation clearly specifies "unspecified ulna" and an open fracture type of IIIA, IIIB, or IIIC.
• Verify that the encounter is subsequent to the initial treatment and that delayed healing is explicitly documented.
• Do not use for initial encounters or for closed fractures.
