Displ transverse fx shaft of l ulna, 7thJ

This code signifies a left ulna fracture, specifically a displaced break across the shaft, that was initially an open fracture of severe type (IIIA, IIIB, or IIIC). The patient is currently in a phase where the fracture is not healing at the expected rate, indicating delayed union.

Use this code for follow-up encounters when a patient with a previously treated severe open transverse ulna shaft fracture of the left arm is experiencing delayed healing. This applies when the initial injury involved significant soft tissue damage and bone exposure, and the healing process is now prolonged.

• Ensure documentation specifies "left ulna" and "transverse fracture of shaft."
• Verify the original injury was an "open fracture type IIIA, IIIB, or IIIC" and that delayed healing is explicitly noted.
• This "J" seventh character indicates a subsequent encounter for delayed healing, not initial treatment or routine follow-up.
