Nondisp seg fx shaft of rad, unsp arm, 7thH

This code signifies a segmental fracture of the shaft of the radius that is not displaced, located in an unspecified arm. It specifically applies during a subsequent encounter where the initial injury was an open fracture of either Type I or Type II, and the healing process is delayed.

This code is appropriate when a patient presents for follow-up care of a previously diagnosed open segmental radial shaft fracture (Type I or II) that is not healing as expected. It should be used when documentation confirms delayed union of the fracture in an unspecified arm.

• Ensure documentation specifies "segmental" and "nondisplaced" for the radial shaft fracture.
• Verify the initial injury was an "open fracture type I or II" and that the current encounter is for "delayed healing."
• Confirm the laterality is unspecified; otherwise, a more specific code for left or right arm should be used.
