CPT 95165 "Professional services for the supervision of preparation and provision of antigens for allergen immunotherapy; single or multiple antigens (specify number of doses)"

I have a physician that supervises a nurse that mixes the allergy antigens in a hospital outpatient location. Is it appropriate to bill this code by the physician for his supervision and bill this code by the hospital for the antigens and nurse time? This code is on the Medicare Physician Fee Schedule and on Medicare Addendum B.
