Important billing and coverage reminders

Please be aware that if prior plan approval of these medications is not given by Blue Cross NC, the service(s) may not be covered under the member’s Medicare Advantage plan, and the provider may be responsible for the entire cost of the drug and associated service(s). Providers cannot bill members for services when prior plan approval is required but was not obtained by the provider before services were rendered.

Additionally, if the member changes Blue Cross NC Medicare Advantage plans, you may need to certify they have met our medical necessity criteria under the new policy for the medication(s) in question.
