Unsp inj unsp blood vess at shldr/up arm, unsp arm, init

This code indicates an injury to a blood vessel in the shoulder or upper arm region, where the specific type of blood vessel (e.g., artery, vein) and the exact location within the shoulder/upper arm are not documented. It also signifies that the affected arm is not specified, and this is the initial encounter for the injury.

Use this code when documentation clearly states a blood vessel injury in the shoulder or upper arm, but lacks specificity regarding the vessel type, precise anatomical site, or laterality of the arm. This code is appropriate for the initial treatment or evaluation of such an injury when more detailed information is unavailable at the time of coding.

• Avoid using this code if the specific blood vessel (e.g., brachial artery, axillary vein) is identified in the medical record.
• Do not use if the laterality (left or right arm) is documented; instead, choose a more specific code.
• This code is for initial encounters only; subsequent care would require a different 7th character.
