Nondisp seg fx shaft of rad, l arm, 7thR

This code describes a left radius shaft fracture that involves multiple segments and is not displaced. It specifically indicates a subsequent encounter for an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, where the fracture has healed in an unsatisfactory position (malunion).

Use this code when documenting follow-up care for a patient with a previously treated open, segmental, nondisplaced left radial shaft fracture that has developed malunion. This applies to situations where the initial injury was a severe open fracture (type IIIA, IIIB, or IIIC) and the patient is now being managed for the resulting malunion.

• Ensure documentation clearly specifies "left arm" and "shaft of radius" to differentiate from other forearm fractures.
• Verify that the original fracture was an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, and that malunion is explicitly documented.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture or the malunion.
