Compare benefits

Each Part D plan has a different range of benefits. Before enrolling in a Part D plan, you should request the plan’s current formulary (drug list), coverage rules, and network pharmacies.

Formulary and tiers

Each Part D plan covers different prescription drugs, which will all be listed on the plan’s formulary. You should find a plan that covers your prescribed medications. You may have to pay out-of-pocket for prescriptions that are not on a plan’s approved drug list.

You also should review the Part D plan’s tiers. Different plans may place the same drug in different tiers, which will affect your out-of-pocket costs. For example, one plan may put a certain brand-name drug in Tier 1, but another plan may put the same brand name drug in Tier 2, which could require a higher co-payment.

Coverage rules

Part D plans also have varying coverage rules that can affect your access to certain prescriptions. You should review the rules for quantity limits, prior authorization, and step therapy before enrolling in a plan.

Network pharmacies

Some Part D plans have contracts with pharmacies. If you visit in-network pharmacies, your prescription drug costs may be lower. If you fill a prescription at a non-network pharmacy, your plan may charge you more or not cover your medication costs at all.

Check to see if your preferred pharmacy is in your plan’s network.

Compare costs

Part D plan costs vary widely depending on plan premiums and out-of-pocket costs.

It is important to find a plan that fits your coverage needs and covers all of your prescription drugs before comparing plan premiums. If you enroll in a plan that does not cover all of your medications, you may be forced to pay out-of-pocket for these drugs.

In addition to plan premiums, you should compare other Part D plan out-of-pocket costs, including deductibles, coinsurance, and copayments, which may be different for each plan.
