Unsp inj blood vessels at shldr/up arm, right arm, init

This code signifies an unspecified injury to a blood vessel, other than the major arteries or veins, located in the right shoulder or upper arm region. The nature of the injury (e.g., laceration, contusion, rupture) is not documented or is unknown at the time of the initial encounter.

This code is appropriate for initial presentations where a patient has sustained trauma to the right shoulder or upper arm, and there is clinical evidence of blood vessel damage (e.g., hematoma, pulsatile mass, diminished pulse) but the specific vessel or type of injury is not yet definitively diagnosed. It is used when the injury is to a blood vessel not covered by more specific codes for major arteries or veins.

• Ensure the injury is to a blood vessel other than the axillary, brachial, or subclavian artery/vein, or their major branches, for which more specific codes exist.
• Only use for the initial encounter for treatment of the injury. Subsequent care will require a different seventh character.
• Avoid using this code if a more specific diagnosis of the blood vessel and injury type is available.
