Unsp fx the low end l rad, 7thN

This code signifies a nonunion of an unspecified fracture of the lower end of the left radius, specifically when the initial injury was an open fracture classified as Type IIIA, IIIB, or IIIC. Nonunion indicates that the bone has failed to heal completely after a previous attempt, and this code is used during subsequent treatment encounters for this persistent issue.

Apply this code for patients presenting for ongoing management of a left distal radius fracture that has not healed, following an initial open injury of a severe nature (Gustilo-Anderson Type IIIA, IIIB, or IIIC). This is appropriate when the patient is seen for procedures or evaluations related to the nonunion, such as bone grafting, hardware revision, or monitoring.

• Confirm documentation specifies "nonunion" and a prior open fracture of the lower end of the left radius.
• Ensure the original open fracture was explicitly documented as Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
