Nondisp seg fx shaft of ulna, l arm, 7thJ

This code describes a fracture involving a segment of the ulna's shaft in the left arm, where the bone fragments remain in their normal alignment. It specifically indicates that this is an open fracture of a severe type (IIIA, IIIB, or IIIC) that is not healing as expected. The "subsequent encounter" designation means this code is used for follow-up care after the initial treatment of the injury.

Use this code for patients presenting for ongoing management of a previously treated left ulnar shaft fracture that was open and severe, and is now demonstrating delayed healing. This would apply to follow-up appointments, cast changes, or evaluations for non-union or malunion where delayed healing is the primary concern. It is appropriate when the patient has already received initial definitive treatment for the fracture.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the fracture is indeed nondisplaced and located in the shaft of the ulna, left arm.
• Confirm the original injury was classified as an open fracture type IIIA, IIIB, or IIIC.
