Unsp injury of blood vessels at shldr/up arm, left arm, init

This code signifies an injury to a blood vessel, other than the main arteries or veins, in the left shoulder or upper arm region, where the specific type of injury (e.g., laceration, contusion) is not documented. It indicates the initial treatment for such an injury.

Use this code when a patient presents with a left shoulder or upper arm blood vessel injury that is not a major artery or vein, and the physician's documentation does not specify the exact nature of the injury. This is appropriate for the initial encounter for treatment of the injury.

• Ensure the documentation clearly specifies the left arm and the shoulder/upper arm level.
• Only use this code when the specific blood vessel injury type is unspecified; otherwise, a more specific code should be chosen.
• Verify this is the patient's initial encounter for this specific injury. Subsequent encounters will require a different 7th character.
