Nondisp transverse fx shaft of unsp ulna, 7thH

This code signifies a transverse break in the shaft of the ulna that has not shifted out of alignment, occurring in a patient who initially sustained an open fracture (Type I or II) and is now experiencing a delay in the healing process. The "unspecified ulna" indicates that laterality (left or right) was not documented.

This code is appropriate for follow-up encounters where a patient with a previously treated open transverse ulnar shaft fracture (Gustilo-Anderson Type I or II) is presenting with evidence of delayed union. This includes situations where the fracture site is not showing expected callus formation or clinical stability within the typical healing timeframe.

• Ensure documentation clearly specifies "delayed healing" for an open transverse ulnar shaft fracture.
• Verify the original fracture was an open fracture, Type I or II, as this impacts the "subsequent encounter" character.
• Confirm the fracture is nondisplaced and transverse, and that laterality of the ulna is not specified in the medical record.
