Re:      Pharmacy COVID-19 Booster Update


This notice provides an update for coverage of new COVID-19 boosters. The Illinois Department of Healthcare and Family Services (HFS) reimburses Medicaid participating pharmacies an administration fee through National Council for Prescription Drug Programs (NCPDP) claim submission for all federally allocated COVID-19 vaccines.

The coverage update applies to claims for customers covered under traditional Medicaid fee-for-service (FFS) and the HealthChoice Illinois (HCI) managed care organization (MCO) plans. All COVID-19 vaccines should be given in accordance with Centers for Disease Control (CDC) guidance.

New Pfizer-BioNTech Booster Vaccine for Persons Aged 12 and Older
The Pfizer-BioNTech COVID-19 Vaccine, Bivalent Product booster dose is available effective with dates of service beginning August 31, 2022, for persons aged 12 years and older.

New Moderna Booster Vaccine for Persons Aged 18 and Older
The Moderna COVID-19 Vaccine, Bivalent Product booster dose is available effective with dates of  service beginning August 31, 2022, for persons aged 18 years and older.

Per the CDC, the updated COVID-19 boosters add Omicron BA.4 and BA.5 spike protein components to the current vaccine composition, helping to restore protection that has waned since previous vaccination by targeting variants that are more transmissible and immune-evading.
