Oth fx upr end unsp rad, 7thN

This code describes a situation where a patient has an open fracture of the upper part of the radius bone (near the elbow) that is not healing properly (nonunion). Specifically, it applies when the fracture was a severe open type (IIIA, IIIB, or IIIC) and the patient is presenting for follow-up care after the initial treatment.

Use this code for subsequent encounters when managing an open, comminuted, or severely contaminated upper radial fracture that has failed to unite. This applies to patients undergoing ongoing treatment, such as debridement, bone grafting, or revision fixation, for a previously treated open fracture of the proximal radius.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original fracture was classified as an open type IIIA, IIIB, or IIIC.
• Do not use for initial treatment or routine follow-up of a healing fracture.
