Clinical Guidance for Administering Additional Dose of COVID-19 Vaccine

August 20, 2021 - On Aug. 12, the Food and Drug Administration (FDA) amended its Emergency Use Authorizations (EUA) of the Pfizer and Moderna COVID-19 vaccines, allowing moderately to severely immunocompromised individuals to receive a third dose after an initial 2-dose series. This applies to the Pfizer vaccine for individuals aged 12 and older and the Moderna vaccine for individuals 18 years and older. At this time, the Centers for Disease Control and Prevention (CDC) is not recommending additional doses of vaccine for people who were initially vaccinated with the one-dose Johnson & Johnson vaccine.

Clinicians should use their best clinical judgement in determining if patients meet this eligibility criteria. No special attestation is required by the patient or their physician, and Michigan Department of Health and Human Services (MDHHS) will not be asking COVID-19 vaccine providers to verify eligibility for patients receiving a third dose. COVID-19 providers should work to remove any potential barriers to accessing a third dose for eligible people, which could include individuals who have received organ or stem cell transplants, have advanced or untreated HIV infection, or are in active treatment for cancer or taking high-dose cortiocosteriods.

Registering for COVID-19 Vaccination Program

According to MDHHS Chief Medical Executive Dr. Joneigh Khaldun, Michigan has ample supply of both the Pfizer and Moderna vaccines. Currently, more than 3,900 Michigan healthcare professionals are already registered as “COVID-19 Ready Providers” to administer COVID-19 vaccines. However, more than 3,000 additional healthcare professionals are eligible and have not yet enrolled.

Coding & Payment

Effective Aug. 12, CMS and MDHHS will pay for administering additional doses of COVID-19 vaccines to Medicare and Medicaid beneficiaries, respectively, consistent with the FDA EUAs, using CPT code 0003A for the Pfizer vaccine and CPT code 0013A for the Moderna vaccine.

COVID Booster Shots Available Beginning in September

Starting the week of Sept. 20, U.S. adults who received their second dose of the Pfizer or Moderna COVID-19 vaccine at least 8 months earlier may be encouraged to receive a booster shot. This plan is contingent on the FDA completing an independent review of the safety and effectiveness of a third dose, and on the CDC’s Advisory Committee on Immunization Practices' recommendations after review of the evidence. The first boosters will be given to people vaccinated earliest in the initial COVID-19 vaccinaton rollout—healthcare workers, residents and staff of long-term care facilities, and other seniors.
