Unsp fx low end r ulna, 7thN

This code describes a situation where a patient has an unconfirmed fracture of the lower part of their right ulna, and they are returning for follow-up care. The initial injury was an open fracture, meaning the bone broke through the skin, and it was a severe type (IIIA, IIIB, or IIIC). Crucially, the fracture has not healed as expected, indicating a nonunion.

Use this code for patients presenting for ongoing management of a right distal ulna fracture that was initially open and severe, but has failed to unite. This would apply during clinic visits, follow-up imaging, or surgical planning for nonunion repair. It signifies a complication in the healing process of a previously treated open fracture.

• Ensure documentation clearly states "nonunion" and specifies the right ulna.
• Verify the initial fracture was indeed an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
