Inj right innominate or subclavian artery, init encntr

This code signifies a specific injury to the right innominate (brachiocephalic) or subclavian artery that doesn't fit into more precise categories like laceration or puncture. It indicates damage such as a contusion, crush injury, or other non-specified trauma to this major blood vessel in the initial phase of treatment.

Apply this code when documentation clearly states an injury to the right innominate or subclavian artery, but the exact nature of the injury (e.g., laceration, transection) is not specified. This is appropriate for initial encounters where the patient is receiving active treatment for the acute injury.

• Ensure the documentation specifies the right side for the innominate or subclavian artery.
• Confirm the injury is not a laceration, puncture, or other more specific type, which would have its own dedicated code.
• Verify this is the initial encounter for treatment of this specific injury; subsequent encounters would use a different seventh character.
