Nondisp spiral fx shaft of rad, unsp arm, 7thR

This code describes a specific type of radius fracture where the bone is broken in a spiral pattern along its shaft, but the bone fragments are still aligned. It indicates that the fracture was initially an open fracture (meaning the skin was broken), classified as Type IIIA, IIIB, or IIIC, and is now in a subsequent encounter where the bone has healed incorrectly, resulting in malunion.

Use this code for follow-up encounters when a patient presents with a previously treated open spiral shaft radius fracture (Type IIIA, IIIB, or IIIC) that has healed in an unsatisfactory position. This code is appropriate when the malunion is documented, and the fracture was initially nondisplaced.

• Ensure documentation specifies "subsequent encounter" and "malunion" for an open Type IIIA, IIIB, or IIIC fracture.
• Verify the fracture is indeed a "nondisplaced spiral fracture of shaft of radius."
• Do not use this code for initial encounters or for fractures without documented malunion.
