Influenza Vaccination - Insured Physician Services

Influenza vaccination is an insured service under the Schedule of Benefits for physician services.

 Fee-for-Service Claims

On April 1, 2001, the requirement that influenza immunization was insured only for people who were eligible to receive publicly funded influenza vaccine was removed. See Bulletin 4367. The fee codes for the administration of influenza vaccine are

                              G590            Influenza immunization- with visit                     $3.70

                              G591            Influenza immunization – sole reason                $8.40

When influenza immunization is the sole service provided during the patient encounter, G591 is payable. The fee for G591 includes any evaluation of the patient with regard to the patient receiving the vaccine. G590 is payable with a visit when the reason for the visit is not related to the flu vaccine. It is inappropriate to claim Active Immunization codes (G538 and G539) for administration of influenza immunization. 

Requirements for Delegation

For payment purposes, the physician must personally administer the vaccine or delegate the procedure in accordance with the rules for delegated procedures i.e.

  • the vaccine is administered by a person who is an employee of the physician; and

  • the person is under the direct supervision of the physician; and

  • the physician is physically present in the office or clinic at which the delegate is administering the vaccine to ensure that the procedure is being performed competently; and

  • the physician is immediately available at all times to approve, modify or otherwise intervene in the procedure as required in the best interest of the patient.

For complete information about physician payment for delegated procedures, see the Schedule of Benefits, General Preamble, B.10, Delegated Procedure, page xxv.

In addition, the College of Physicians and Surgeons of Ontario standards for delegating a controlled act apply when administration of the vaccine is delegated to a person who is not authorized to do so by the Regulated Health Professions Act. For further information about delegating a controlled act, refer to the College of Physicians and Surgeons of Ontario policy statement The Delegation of Controlled Acts dated November 1999.
