Displ spiral fx shaft of ulna, l arm, 7thQ

This code describes a left ulna shaft fracture that is spiral in nature and has shifted from its normal anatomical position. The fracture was initially an open fracture of Type I or II, and the bone is now healing improperly, resulting in a malunion.

This code is used when a patient with a previously open (Type I or II) spiral fracture of the left ulna shaft presents for follow-up care, and imaging or clinical assessment confirms that the bone is healing in a misaligned or deformed position. This indicates a complication of the healing process.

• Ensure documentation specifies "left arm" and "ulna shaft" for laterality and location.
• Verify that the original fracture was an "open fracture type I or II" and that "malunion" is explicitly documented.
• This code is for a subsequent encounter, so an initial encounter code would have been used previously.
