I'm confused about the different tiers in Medicare Part D plans. How do they affect what I pay for my medications?

Answered by 8 licensed agents

Medicare Part D drug tiers are the drug manufacturers' way of controlling costs. It is extremely important to make sure that your drugs are in the formulary, and these tier structures change annually. All Medicare Part D stand-alone drug plans and the Part D drug plans embedded in the Medicare Advantage plans must be analyzed yearly to ensure that you have the proper plan to cover your prescription drugs. Many drug plans utilize the tier structure to determine whether to allow the drug to be used towards the annual deductibles of that drug plan; this should be paid special attention to when selecting a drug plan.

Normally there are 5 tiers with most prescription plans. Tier 1 is preferred generic, Tier 2 is generic, Tier 3 preferred Brand name prescriptions, Tier 4 Nonpreferred And Tier 5 is speciality drugs. Most cases. The lower the Tier, the lower your co-pay. But that's not true all the time, it depends on your prescriptions that you take, your zip code you live in, and what Pharmacy you like to use. I will show you how you can check to see which prescription plan is the best for you and it could change annually!

Most Part D plans exhibit 5 tiers of drugs: 1) Preferred Generic, 2) Non-Preferred Generic, 3) Preferred Brand Name, 4) Non-Preferred Brand Name, and 5) Specialty Drugs. The lowest the tier, the cheaper the copay.

Tiers are determined by Medicare (CMS) and are based upon the costs of bringing the drug to market (research & development, plus the ingredients). There are some categories of drugs that don't fit into that rule like Insulin ($35.00 apiece) and the ever-escalating costs of various inhalers.

My tip on paying the least amount of money is to always check with the online discount websites like GoodRx.com, costplusdrugs.com, simplecare.com, etc. There are also a number of Canadian online discount pharmacies that are available in order to check their cost to you. Please remember that should you decide to use a Canadian pharmacy, the drug cost will NOT be applied toward the 2025 annual drug deductible (max: $2,000.00).

Be advised that in 2025, you have 2 options: A) Using your Part D(rug) plan or in checking the drug formulary within your Advantage plan, vs. B) using an online pharmacy which you've investigated and contains a less expensive amount by printing a coupon from your PC. BUT, you cannot use both for the same drug. You CAN use either A or B for the various drugs you take, some of which might point you to your favorite local drug store, while others might dictate that you drive further away from your home to a "different" pharmacy which has better pricing for your drug. The only inconvenience is that you must check that your doctor knows which pharmacy to fax to with each individual drug/Rx.

Tier 1 and Tier 2 are Generic brands

Tier 3 are Brand Name

Tier 4 are specialty drugs

Each tier has a copay associated with it. Tiers 3 and 4 will trigger the annual deductible to be satisfied. Ask your representative for a breakdown of your Drug Plan.

Each prescription drug has a tier, and the amount you have to pay out of pocket varies depending on the type of drug.

Example:

TIER 1: Preferred Generic

TIER 2: Other Generic

TEAR 3: Preferred brand

TEAR 4: Brand

Special: Special

If you already have a Part D plan, we recommend you check with your insurance company or agent to find out what tier the drug you are taking is.

In summary, the tier your medication is placed on in your Part D plan significantly impacts your out-of-pocket costs. Lower tiers generally mean lower copays, while higher tiers can lead to higher costs.

Medicare Part D organizes drugs into tiers (1-5) within a formulary, based on cost.

Tier 1 includes the lowest-cost generic drugs, while Tier 5 covers high-cost specialty medications. Monthly premiums and drug deductibles vary by plan, with some offering no monthly premiums.
