Displ oblique fx shaft of unsp ulna, 7thH

This code signifies a specific type of broken bone in the forearm, where the ulna bone is fractured obliquely along its shaft and the broken pieces are not aligned. It specifically indicates that the fracture broke through the skin (an open fracture, type I or II) and is being treated in a follow-up visit because the healing process is taking longer than expected.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open oblique shaft fracture of the ulna (type I or II) presents for ongoing management due to delayed healing. This would include follow-up appointments for wound care, cast changes, or assessment of bone healing progress when the healing is not proceeding as anticipated.

• Ensure documentation clearly specifies "delayed healing" for an open fracture type I or II.
• Verify the fracture is indeed of the ulna shaft and is oblique and displaced.
• This code is for subsequent encounters; an initial encounter would use a different code.
