Humana is the fourth-largest company offering Medicare Part D plans. About 3.5 million Medicare beneficiaries have Humana Part D plans as of October 2022.
Humana’s Medicare Part D plans have below-average star ratings from the Centers for Medicare & Medicaid Services, or CMS, falling short on nine out of 12 Medicare Part D quality measures.
While Humana Medicare Part D plans generally make generic drugs affordable with low copay and deductible requirements, coinsurance for brand-name drugs could lead to higher out-of-pocket costs.
Here’s what you should know about Humana Medicare Part D prescription drug plans.

Humana Medicare Part D drug formulary tiers
A formulary is a list of the prescription drugs covered by an insurance plan. The plans often organize different kinds of drugs into tiers according to the cost of the drugs.
Humana’s prescription drug plans use a five-tier formulary:
Tier 1: Preferred generics
More common, lower-cost generic prescription drugs.
Tier 2: Generics
Higher-cost generic prescription drugs and some lower-cost brand-name drugs.
Tier 3: Preferred brand
Brand-name drugs with no generic drug equivalent.
Tier 4: Non-preferred drug
Higher-priced brand-name and generic drugs with no preferred cost sharing.
Tier 5: Specialty tier
High-cost drugs that meet Medicare’s definition of a specialty drug.
Each tier has copay or coinsurance requirements. You’ll generally pay more for drugs listed in higher tiers up to Tier 4, but Tier 5 specialty drugs have a lower coinsurance requirement than Tier 4 drugs.
The drugs included in tiers and what you’ll pay for each tier depends on your choice of prescription drug plan and what kind of pharmacy you use. For example, Humana plans sometimes have the lowest copays for prescriptions you fill through Humana-preferred mail-order pharmacies. For retail pharmacies, preferred (in-network) pharmacies can have significantly lower cost-sharing requirements than non-preferred pharmacies.
Deductibles can also apply differently depending on the formulary tier. For example, the Humana Walmart Value Rx and Humana Premier Rx plans have no deductible for Tier 1 and Tier 2 drugs. The Humana Basic Rx plan has a deductible for all tiers.
Humana’s $0-copay options vary by both plan and region:
Humana Walmart Value Rx: Copays of $0-$3 for Tier 1 drugs from preferred mail-order pharmacies and $0-$1 for Tier 1 drugs from preferred retail pharmacies, depending on state/region.
Humana Basic Rx: $0 copays for Tier 1-2 drugs from preferred mail-order pharmacies. $0 copay or 7% coinsurance for Tier 1 drugs from preferred retail pharmacies, depending on state/region.
Humana Premium Rx: $0 copays for Tier 1-2 drugs from preferred mail-order pharmacies.
Cost-sharing requirements for higher tiers can quickly get more expensive. As a result, it’s important to check where your medications and pharmacies fall on each plan’s formulary.
Coinsurance vs. copay requirements
You'll also want to check whether you’ll pay a copay or coinsurance for your medications. Copays are set dollar amounts, so it’s easy to see what you’ll pay. Coinsurance is a percentage of the price for your medications, so coinsurance requirements can be more unpredictable and more expensive.
Humana starts charging coinsurance rather than copays at different formulary tiers for each of its plans:
Humana Walmart Value Rx: Copays for Tiers 1-2; coinsurance for Tiers 3-5.
Humana Basic Rx: Copays for Tiers 1-2 from preferred mail-order pharmacies. Tier 1-2 drugs from retail pharmacies have either copays or coinsurance depending on your state/region. Coinsurance for Tiers 3-5.
Humana Premier Rx: Copays for Tiers 1-3; coinsurance for Tiers 4-5.
You can enter your medications and pharmacy information on Humana’s website to see which drugs are covered and review your estimated costs with different plan options.

Find the right Medicare Part D prescription drug plan
The interactive tool on Medicare.gov can help you find a Medicare Part D plan that covers your prescriptions. It also helps you compare costs among Medicare Part D and Medicare Advantage plans available to you.
Here are some things to keep in mind when comparing plans:
Check the formulary: You’ll want to make sure the medicines you currently take and, importantly, any you think you might need in the future, are covered under each of the plans you’re considering. Talk to your health care providers about what brand-name and generic medicines to look for and any alternatives that may also work in case you can’t find your current medicines on the plans available in your area.
Look for plan changes: Formularies change frequently. Your insurer should send you a Notice of Plan Change when the formulary changes. Read that document carefully.
Check the pharmacy network: Most Medicare Part D plans negotiate with a network of pharmacies for the lowest cost. Check to see if your pharmacy or an equally convenient one is in the plan’s network. Also, compare prices for using mail order.
If your plan does change, and the change affects the prescription drugs you need, you can switch plans during Medicare's open enrollment period, Oct. 15 to Dec. 7. Changes go into effect on the following Jan. 1.
