Annual Medicare drug plan changes: Examples of how 2022 Medicare Part D plans change formulary cost-sharing.

Annual Medicare plan changes · published Oct 16, 2021

As in past years, some 2021 Medicare Part D plans are changing their cost-sharing designs for 2022 prescription drug purchases.  Cost-sharing is what you will pay for your Medicare Part D formulary drugs and can be either a fixed-copay (Tier 3 drugs are a $47 co-pay) or cost-sharing can be a percentage of the drug's retail cost (25% of retail).  Each year, Medicare drug plans can also change the structure of the plan's formulary or drug list and add - or take away - formulary tiers - or the plan can move drugs from one Tier to another.

Adding new formulary drug tier - For example, the Prescription Blue Select plan will change from a single drug tier for all formulary drugs to a five (5) tier cost-sharing structure in 2022.  In 2022, Prescription Blue Select plan formulary will change as shown in the chart below.

What do the 2021/2022 plan changes mean to you?
  • Tier 1 preferred generics with a retail cost over $4 will be less expensive in 2022.
  • Tier 2 generics with a retail cost over $20 will be less expensive.
  • The cost of Tier 3 preferred brand drugs with a retail cost over $140 will be less expensive than last year - and this tier has the largest number of drugs.
  • The cost of Tier 4 non-preferred drugs is increasing from 25% to 45% of retail drug costs.
  • You can also see from the chart that the number of drugs being covered by this plan is decreasing by 51 - and you will need to contact your 2021 plan to ensure that your medications are still covered by the 2022 plan.
Changing the cost-sharing for a formulary tier - In another example, the 2021 California SilverScript Choice (PDP) plan formulary covers 1,061 medications as Tier Three "Preferred Brand" medications (with a $35 copay).   In 2022, Tier Three "Preferred Brand" will have a 17% coinsurance.

What do the 2021/2022 plan changes mean to you?
  • The changes from a $47 co-pay to a 17% of retail cost-sharing may mean that you are paying less for your Tier 3 medications in 2022. So, if your Tier 3 drugs have a retail price of under $206, you will save money in 2022 with the new 17% cost-sharing.
  • You will pay slightly less for your Tier 4 and 5 medications in 2022.
