COVID-19 Vaccine - Adverse Reactions

Anthem Blue Cross and Blue Shield (Anthem) is aware that some of our members may have experienced an adverse physical reaction to the COVID-19 vaccine. Beginning October 29, 2021, Anthem expanded coverage for those members under-going treatment related to this diagnosis. If you submit a claim for services related to an adverse physical reaction to the COVID-19 vaccine, it is important that you use a CS modifier to identify these services so that Anthem can correctly process the claim.

Anthem will continue to closely monitor COVID-19 developments and will update you as we receive new information and guidance.
