2021Formulary (drug list)

The formulary, also known as a drug list, for each Blue MedicareRx plan includes most eligible generic and brand-name drugs. All the drugs we cover are carefully selected to provide the greatest value while meeting the needs of our members.

Drugs on the formulary are organized by tiers. Generally, a drug on a lower tier will cost less than a drug on a higher tier. If you’re interested in saving money on your prescriptions, discuss with your doctor whether switching to a similar drug on a lower tier might work for you.

Formulary tiers

Tier Description
Tier 1 Certain generic drugs that are available at the lowest copayment for our members
Tier 2 Higher cost generic drugs available at a higher copayment than Tier 1 generic drugs
Tier 3 Common brand-name and some higher cost generic drugs
Tier 4 High cost generic and non-preferred drugs, many of which may have lower cost options available on Tier 1, 2 or 3
Tier 5 Unique and/or very high-cost brand and some generic drugs of which you pay a percentage of the drug cost; some may require special handling and/or close monitoring

Tier assignments vary by plan. Use the Drug Pricing Tool to price the medications you are currently taking and see which Blue MedicareRx plan is best for you.

Formulary updates

Blue MedicareRx formularies may change during a calendar year if we remove a drug, change a drug’s tier, or add a special coverage requirement. If a change affects a drug you take, we will notify you at least 60 days in advance, as required by Medicare. Sometimes, we must remove a drug immediately for safety reasons or due to its discontinuation by the manufacturer. If a sudden removal occurs, we will notify our affected members as soon as possible.

We may immediately remove a brand name drug on our Drug List if we are replacing it with a new generic drug that will appear on the same or lower cost sharing tier and with the same or fewer restrictions. Also, when adding the new generic drug, we may decide to keep the brand name drug on our Drug List, but immediately move it to a different cost-sharing tier or add new restrictions. We may not tell you in advance before we make that change-even if you are currently taking the brand name drug.

Formulary coverage requests

Certain drugs on Blue MedicareRx formularies have special coverage requirements to ensure they’re used in a safe way and to help control costs. These requirements include:

  • Prior authorization – you will need to obtain approval before you fill your prescription
  • Quantity limit – There is a limit to the amount of the drug the plan will cover with each prescription filled
  • Step therapy – You may be required to try an alternative drug before this drug is covered
  • Limited access – This prescription may be available only at certain pharmacies

If you believe your use of a drug meets all special requirements, or that you should be exempt from a requirement, you and/or your doctor must request a coverage determination before the plan will cover your drug. You can also request that the plan cover a drug that is not included in the formulary.
