Nondisp fx of head of unsp rad, 7thN

This code describes a fracture of the radial head that is not displaced, meaning the bone fragments remain in their normal anatomical position. This specific code is used during a subsequent encounter for an open fracture, indicating the skin and soft tissues were significantly damaged (Type IIIA, IIIB, or IIIC) at the time of the initial injury, and the fracture has failed to heal properly, resulting in a nonunion.

Use this code when documenting follow-up care for a patient with a previously treated open radial head fracture (Type IIIA, IIIB, or IIIC) where imaging and clinical assessment confirm a nonunion. This applies to situations where the initial injury involved significant soft tissue damage and the fracture has not united after the expected healing period.

• Ensure documentation clearly specifies "nondisplaced" and "nonunion" for the radial head fracture.
• Verify the original injury was an "open fracture type IIIA, IIIB, or IIIC" to justify this specific code.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would be coded differently.
