Inj ulnar artery at wrist and hand level of left arm, subs

This code signifies a non-traumatic, non-open injury to the ulnar artery in the left wrist or hand that is not further specified as a laceration or puncture. It indicates damage to the artery that could result from various mechanisms other than a clean cut or stab wound, such as a crush injury, contusion, or other blunt force trauma.

This code is appropriate for follow-up encounters when a patient is receiving ongoing treatment for an injury to the left ulnar artery at the wrist or hand level, and the initial injury was not a laceration or puncture. It is used after the acute phase of care, for example, during rehabilitation, wound care, or monitoring for complications.

• Ensure the injury is to the ulnar artery specifically and located at the wrist or hand level of the left arm.
• Verify that the encounter is for subsequent care, not the initial treatment of the injury.
• Confirm the injury mechanism is "other specified" and not a laceration (S65.01-) or puncture (S65.02-).
