Billing & Claims
CareFirst wants to keep you informed of the benefit updates we are making to ensure our members, your patients, have access to the care they need. Please note that general guidance appears first on this page, followed by Medicare Advantage-specific guidance at the bottom.
As new codes are released, please allow 30 days before billing the new codes to allow for us to have them configured in our systems appropriately.
CareFirst members will pay $0 for any authorized COVID-19 vaccine. Providers will be reimbursed by CareFirst for administration of a vaccine. Effective September 11, 2023, the vaccine is no longer paid for by the federal government. Providers should submit claims for the cost of the vaccine.
Effective for dates of service on and after June 8, 2021, CareFirst is increasing fees for in-home vaccinations in alignment with the CMS. Professional providers may bill M0201 in addition to existing vaccine administration codes for COVID-19 vaccines given in the home. This increase is designed to promote vaccine accessibility in vulnerable and hard-to-reach populations.
Medical providers should submit claims for vaccine administration using the appropriate codes below. Dental providers should refer to the information under the Dental tab for the appropriate CDT and CPT codes.
