Nondisp spiral fx shaft of ulna, unsp arm, 7thM

This code describes a situation where a patient has a non-displaced spiral fracture of the shaft of the ulna, located in an unspecified arm. The fracture is an open fracture of type I or II, and the current encounter is for follow-up care due to the fracture not healing properly (nonunion).

Use this code when documenting subsequent care for an open spiral ulna shaft fracture (Type I or II) that has failed to unite. This applies to situations where the specific arm (left or right) is not documented. It is appropriate for follow-up visits, cast changes, or other ongoing management of the nonunion.

• Ensure documentation specifies "nonunion" and "subsequent encounter" for this code to be appropriate.
• Verify the fracture is explicitly described as a "spiral fracture of shaft of ulna" and "nondisplaced."
• Only use this code when the laterality (left or right arm) is not specified in the medical record.
