Nondisp oblique fx shaft of unsp ulna, 7thJ

This code describes a follow-up encounter for a patient with a nondisplaced oblique fracture of the shaft of an unspecified ulna. The initial injury was an open fracture classified as Type IIIA, IIIB, or IIIC, and the current encounter addresses delayed healing of that fracture.

Use this code when documenting subsequent care for an open ulnar shaft fracture (Type IIIA, IIIB, or IIIC) that is not healing as expected. This applies to situations where the fracture is nondisplaced and the patient is returning for ongoing management of the delayed union.

• Ensure the documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the original fracture was an open Type IIIA, IIIB, or IIIC to justify this specific code.
• Confirm the fracture is of the ulnar shaft and is nondisplaced.
