Laceration of ulnar artery at wrs/hnd lv of right arm, subs

This code signifies a tear or cut in the ulnar artery located in the right wrist or hand, specifically when the patient is receiving follow-up care after the initial injury. This type of injury can lead to significant bleeding and compromise blood flow to the hand.

Use this code for patients presenting for subsequent treatment, such as wound care, follow-up examinations, or management of complications related to a previously treated laceration of the right ulnar artery. This applies after the initial acute phase of treatment has concluded.

• Ensure documentation clearly specifies the "subsequent encounter" for this injury.
• Verify the injury is to the ulnar artery, not another vessel, and is located at the wrist or hand level of the right arm.
• Always pair with an external cause code (V, W, X, Y category) to describe the circumstances of the injury.
