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

This code signifies a documented injury to the ulnar artery within the forearm that is not a laceration, puncture, or contusion. The specific nature of the injury is identified but does not fall into the more common categories, and the affected arm is not specified.

Apply this code when medical documentation clearly states an "other specified" type of injury to the ulnar artery in the forearm, such as a crush injury or avulsion, and the laterality of the arm is not recorded. This is appropriate for the initial treatment encounter for such an injury.

• Ensure the documentation specifies an "other" type of injury to the ulnar artery, not a laceration, puncture, or contusion.
• Confirm the injury is located at the forearm level.
• Only use this code when the medical record does not specify whether the injury is to the right or left arm.
