Oth fx upr end r ulna, 7thN

This code signifies a non-healing fracture in the upper portion of the right ulna, specifically an open fracture (where the bone broke through the skin) classified as Type IIIA, IIIB, or IIIC. The "subsequent encounter" indicates that the patient is receiving ongoing treatment for this previously diagnosed injury, which has failed to unite properly.

Use this code for patients presenting for follow-up care, cast changes, or surgical intervention for a nonunion of a severe open fracture of the proximal right ulna. This applies when the initial injury was an open fracture with significant soft tissue damage, periosteal stripping, or arterial injury.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the original fracture was an open fracture of Type IIIA, IIIB, or IIIC.
• Do not use for initial encounters or for fractures that are healing normally.
