There are currently 964,000 Indiana residents who have a Medicare Part D prescription drug plan alongside their Medicare. Nearly 634,000 supplement their Original Medicare with Medicare Part D. Another 338,000 beneficiaries combine a prescription drug plan with their Medicare Advantage plan.

Indiana Medicare Part D plans for 2024

Medicare Part D is the fourth pillar of Medicare in Indiana. It focuses exclusively on prescription drugs. Once you enroll in a plan, you pay a monthly premium and an annual deductible in exchange for prescription drug discounts.

Your Part D plan will have a formulary that tells you which drugs the plan covers and your costs.

Part D plans with the lowest premium in Indiana

The chart below might look like a list of Indiana’s least to most expensive Medicare Part D plans, but don’t be fooled. Just because UnitedHealthcare has the highest monthly premium doesn’t mean it’s the most costly option.

Clear Spring and Humana are more expensive if you calculate the costs of paying monthly premiums for a year plus your deductible. But Humana also has a 4-star customer rating.

Aetna Has the lowest monthly premium and an average deductible. It also has a 3-star customer rating. Just be sure to check their formulary and make sure they provide the drugs you need.

Aetna $6.80 $480 3 No
Wellcare $12.90 $480 3 No
Clear Spring $22.20 $480 2 No
Humana $22.70 $480 4 No
UnitedHealthcare $29.30 $310 4 No

Part D plans with a zero-dollar deductible in Indiana

Some providers won’t make you if you don’t like paying deductibles. But is it worth it? Below, the zero deductible Aetna plan is the only one that’s cost-competitive with the programs from the previous selection.

You’re better off paying a deductible once you look at more expensive Medicare Part D plans in Indiana, like Wellcare. High-premium plans with no gap coverage can be costly.

Anthem provides gap coverage, has a 4-star customer service rating, and comes with a friendly, affordable $69 premium. UnitedHealthcare, conversely, costs 34% more and has a less favorable rating.

Aetna $58.80 $0 3 Yes
Wellcare $68.70 $0 3 No
Anthem $69.00 $0 4 Yes
UnitedHealthcare $92.50 $0 3 Yes

Part D plans with gap coverage in Indiana

If you need a lot of prescription drugs, gap coverage is essential. Without it, your Medicare Part D plan in Indiana could become prohibitively expensive. For that reason, purchasing UnitedHealthcare’s deductible plan can keep costs down.

But if you’d rather pay a $0 deductible, Anthem is the only one with a 4-star customer service rating. These ratings are important because they show how happy most beneficiaries are with their plans.

Aetna is probably the cheapest plan on this list, providing gap coverage and a $0 deductible. And it has a good 3-star customer service rating, too.

UnitedHealthcare $29.30 $310 4 Yes
Cigna $58.10 $100 3 Yes
Aetna $58.80 $0 3 Yes
Anthem $69.00 $0 4 Yes
UnitedHealthcare $92.50 $0 3 Yes

Part D plans with a Low-Income Subsidy in Indiana

Over 280,000 Medicare beneficiaries in Indiana qualify for a low-income subsidy plan. Extra Help subsidizes the premiums, and all will have the deductible removed or reduced. This means programs like UnitedHealthcare stand out for having a four-star customer service rating.

Clear Spring also stands out, but for the opposite reason. It only has a 2-star rating. This rating could signify their limited formulary, poor customer service, or both.

Wellcare, Aetna, and Cigna are all middle-of-the-road in customer service. So choosing them over other available plans might boil down to specific formularies or your doctor’s recommendation.

Wellcare $0 $480 3 No
Clear Spring $0 $480 2 No
Aetna $0 $480 3 No
Cigna $0 $480 3 No
UnitedHealthcare $0 $480 4 No

Amount of beneficiaries that fall into each Part D coverage phase in Indiana

There are four unique coverage phases in each Indiana Medicare Part D plan. The deductible phase is when you pay the total price for your drugs until you meet your deductible.

Next is the initial coverage phase, when your drugs will be the cheapest. The third phase is the coverage gap phase, also known as the donut hole. Once you hit a maximum spending limit, you’ll be in catastrophic coverage for the rest of the year.

As you can see in the chart below, most prescription drug beneficiaries are in and stay in the initial coverage phase. Getting into those later stages is challenging, and you’ll end up back in the deductible phase at the beginning of the following calendar year.

Deductible Phase Initial Coverage Phase Coverage Gap Phase Catastrophic Phase
237,775 389,271 114,840 93,419
