Inj unsp blood vessel at shldr/up arm, unsp arm, init

This code signifies an injury to a blood vessel in the shoulder or upper arm that isn't specifically identified as an artery or vein, and the exact type of injury is also not specified. This diagnosis indicates the initial treatment for such an injury, where the affected arm is not documented.

Apply this code when a patient presents with an acute, unspecified blood vessel injury in the shoulder or upper arm, and the medical record does not specify the type of vessel (artery/vein) or the specific nature of the injury (e.g., laceration, contusion). It is appropriate for the initial encounter for treatment of this injury when the laterality of the arm is not documented.

• Only use this code for the initial encounter for treatment of the injury.
• Avoid this code if the medical record specifies the type of blood vessel (artery or vein) or the specific arm (left/right).
• Always query the provider for more specific details regarding the vessel type, injury type, and laterality if not documented.
