Inj oth blood vessels at shldr/up arm, unsp arm, init

This code signifies a traumatic injury to a blood vessel in the shoulder or upper arm, excluding the major vessels like the subclavian or axillary arteries/veins, that is not further specified as a laceration, puncture, or contusion. It applies when the specific type of blood vessel or the precise nature of the injury is documented as "other specified."

Use this code for initial encounters where documentation indicates an injury to a smaller, named blood vessel (e.g., a brachial artery branch, cephalic vein) in the shoulder or upper arm, but the exact type of injury (e.g., transection, rupture) is not detailed. This is appropriate when the injury is clearly traumatic and not a spontaneous event.

• Ensure the documentation specifies "other specified" injury or a similar vague description for a blood vessel not covered by more specific codes.
• Verify that the injury is to a blood vessel at the shoulder or upper arm level and not a nerve, muscle, or other tissue.
• Confirm this is the patient's initial encounter for this specific injury. Subsequent care would require a different 7th character.
