Unsp fx shaft of l rad, 7thN

This code describes a situation where a patient has an unhealed fracture in the shaft of their left radius, which was originally an open fracture of a severe type (IIIA, IIIB, or IIIC). The "subsequent encounter" indicates that the patient is receiving follow-up care for this ongoing nonunion.

Use this code for patients presenting for continued treatment, evaluation, or management of a previously diagnosed open fracture of the left radial shaft that has failed to heal (nonunion). This applies when the initial open fracture was classified as type IIIA, IIIB, or IIIC, and the current visit is not for the initial treatment of the fracture.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is documented to support this specific code.
• Do not use for initial fracture treatment or for malunion; a different code would apply.
