Inj ulnar artery at forearm level, left arm, init encntr

This diagnosis code indicates a specific injury to the ulnar artery in the left forearm that is not otherwise specified as a laceration, puncture, or contusion. It signifies damage to the artery that could include a tear, rupture, or other defined trauma, occurring at the initial presentation for treatment.

This code is appropriate for documenting acute, non-laceration/puncture/contusion injuries to the left ulnar artery within the forearm region. Examples include blunt trauma causing an arterial dissection or a crush injury resulting in arterial wall damage, when the patient is first seen for this condition.

• Ensure the documentation clearly specifies the left arm and the forearm level of the injury.
• Verify that the injury is to the ulnar artery, not another vessel.
• Confirm this is the patient's initial encounter for this specific injury; subsequent care would use a different seventh character.
