Healthcare Providers

Billing & Claims

During this challenging and unprecedented event, 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.

Billing and Submitting Claims for COVID-19 Vaccines

CareFirst members will pay $0 for any authorized COVID-19 vaccine. Providers will be reimbursed by CareFirst for administration of a vaccine. The vaccine is paid for by the federal government. Providers should not 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. This increase is designed to promote vaccine accessibility in vulnerable and hard-to-reach populations.

Submit claims for administration of the vaccine using the appropriate code(s).

ManufacturerFirst Dose Administration CPTSecond Dose Administration CPT
Pfizer 0001A 0002A
Moderna 0011A 0012A
Janssen (Johnson & Johnson) 0031A n/a

Providers who administer a COVID-19 vaccine for a Medicare Advantage member will need to bill Medicare directly for those costs.

Billing and Submitting Commercial Claims for Coronavirus Treatment through August 31, 2021

CareFirst will continue to waive member cost sharing (copays, coinsurance and deductibles) through August 31, 2021 for in-network or out-of-network visits to a provider’s office, lab fees or treatments related to COVID-19. Though CareFirst is waiving out-of-pocket costs, members may experience balance billing from out-of-network providers.

Providers should not collect copays for these services. If a member does owe a copay or coinsurance after the claim is processed, you can bill the member as you do for all other claims.

For a preview of the changes effective September 1, 2021, please refer to this bulletin.
