Unsp fx the low end r rad, 7thN

This code signifies a previously diagnosed, unspecified fracture of the lower end of the right radius that has failed to heal properly, resulting in a nonunion. The fracture was initially an open fracture classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This code is used during subsequent encounters for ongoing management of this complicated healing process.

This code is appropriate when a patient presents for follow-up care of a nonunion of an unspecified fracture of the distal right radius, where the initial injury was an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC. This would include scenarios such as continued monitoring, surgical intervention for nonunion, or management of complications related to the nonunion.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (right radius) is accurately documented.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
