Unsp fx shaft of unsp ulna, 7thJ

This code signifies a follow-up encounter for an open fracture of the shaft of the ulna, where the specific location on the shaft is not documented, and the fracture is classified as a severe open fracture (Type IIIA, IIIB, or IIIC). The "J" seventh character indicates that the patient is experiencing delayed healing of this open ulnar shaft fracture.

Apply this code when a patient presents for ongoing management of a previously diagnosed open fracture of the ulnar shaft, and the medical record explicitly states delayed healing. This code is appropriate when the specific segment of the ulnar shaft involved is not specified in the documentation.

• Ensure documentation clearly indicates "delayed healing" for the seventh character "J."
• Verify the fracture is explicitly an "open fracture type IIIA, IIIB, or IIIC" to use this specific code.
• If the specific ulna shaft segment is documented (e.g., proximal, midshaft, distal), a more specific code should be used.
