Nondisp oblique fx shaft of r ulna, 7thR

This code describes a situation where a patient has a non-displaced oblique fracture in the shaft of their right ulna, which was initially an open fracture of type IIIA, IIIB, or IIIC. The current encounter is for the management of malunion, meaning the fracture has healed, but in an unsatisfactory or deformed position.

Use this code for follow-up encounters when a patient with a previously diagnosed open oblique fracture of the right ulnar shaft (specifically types IIIA, IIIB, or IIIC) is being treated for malunion. This indicates that the initial healing process resulted in an anatomical deformity requiring further intervention or management.

• Ensure the documentation clearly specifies "malunion" as the reason for the current encounter, not delayed union or nonunion.
• Verify the original fracture was an open fracture of type IIIA, IIIB, or IIIC, as this significantly impacts code selection.
• Confirm the fracture is of the right ulna shaft and is described as "nondisplaced oblique."
