Displ commnt fx shaft of ulna, unsp arm, 7thD

This code describes a specific type of forearm fracture involving the ulna bone. It indicates that the break is in the main shaft of the ulna, the bone fragments are separated (displaced) and shattered into multiple pieces (comminuted), and the location of the injury is not specified as left or right arm. The "D" suffix signifies that this is a follow-up encounter for a closed fracture that is healing normally.

This code is appropriate for subsequent visits when a patient is receiving ongoing care for a previously diagnosed displaced comminuted ulna shaft fracture, and the fracture is progressing through routine healing without complications. This includes follow-up appointments for cast changes, wound checks (if applicable to a closed fracture), or physical therapy evaluations during the healing phase.

• Ensure the documentation specifies "subsequent encounter" and "routine healing" for a closed fracture.
• Verify that the fracture is indeed comminuted and displaced, and located in the shaft of the ulna.
• If the arm later develops complications or delayed healing, a different seventh character would be required.
