Unsp fx upr end unsp rad, 7thN

This code describes a fracture of the upper part of the radius bone (near the elbow) that was initially an open fracture (meaning the skin was broken) of a severe type (IIIA, IIIB, or IIIC). The fracture has not healed properly, indicating a nonunion, and this encounter is for follow-up care after the initial treatment. The specific location and type of fracture within the upper radius are not documented.

Use this code for subsequent encounters when a patient presents with a previously treated, severe open fracture of the proximal radius that has failed to unite. This applies when the exact nature of the fracture (e.g., neck, head) was not specified in the initial documentation. This code is appropriate for ongoing management of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies a "subsequent encounter" for an open fracture type IIIA, IIIB, or IIIC.
• Only use this code when the specific part of the upper radius fractured (e.g., head, neck) is not documented.
• Verify that the initial injury was indeed an open fracture of the specified severe types.
