Displaced transverse fracture of shaft of unsp ulna, init

This code signifies a break in the middle section of the ulna bone, one of the two long bones in the forearm, where the bone fragments are not properly aligned. The specific location is the shaft, and the fracture runs across the bone. The "unspecified" nature indicates that the laterality (left or right arm) is not documented.

This code is appropriate for initial encounters with patients presenting with a newly diagnosed, non-open transverse fracture of the ulnar shaft that requires treatment. It is used when the physician's documentation confirms displacement but does not specify whether the fracture is on the left or right side.

• Ensure documentation specifies "transverse" and "shaft" for accurate code selection.
• Verify that the encounter is the "initial encounter" for a closed fracture.
• If laterality (left/right) is documented, a more specific code should be used.
