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
[5]
:

Drug tier

Description

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.

$0-deductible options
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.

$0-copay options
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.
