Nondisp oblique fx shaft of l ulna, 7thJ

This code describes a specific type of ulna fracture involving an oblique break in the shaft of the left ulna, where the bone fragments remain in their normal anatomical alignment. It indicates that the fracture is an open type IIIA, IIIB, or IIIC, meaning there is a break in the skin and soft tissue communicating with the fracture site, and the patient is in a subsequent phase of care with delayed healing.

This code is appropriate for follow-up encounters for patients with a previously diagnosed nondisplaced oblique fracture of the left ulna shaft that was initially an open fracture (types IIIA, IIIB, or IIIC). It should be used when documentation explicitly states that healing is not progressing as expected, indicating delayed union.

• Ensure documentation specifies "nondisplaced" and "oblique" for the fracture morphology.
• Verify the laterality is "left" and the specific bone is the "ulna shaft."
• Confirm the encounter is for a "subsequent encounter" and that "delayed healing" is clearly documented for an open fracture type IIIA, IIIB, or IIIC.
