Louisiana Part D Plans for 2027: 8 Stand-Alone Drug Plans From 4 Insurers, Down From 10

BATON ROUGE — Louisiana retirees shopping for stand-alone Medicare prescription drug coverage in 2027 will see a smaller menu than the one offered this year. According to the CMS 2027 Landscape file, 8 stand-alone Part D plans from 4 insurers will be sold across the Louisiana Part D region, down from 10 plans and 5 insurers in 2026. Choices made during Medicare Open Enrollment 2027, which runs October 15 through December 7, 2026, take effect January 1, 2027.

How many stand-alone Part D plans are offered in Louisiana for 2027?

Louisiana will have 8 stand-alone Medicare Part D plans from 4 insurers for 2027, according to the CMS Landscape file. That is down from 10 plans and 5 insurers in 2026. These stand-alone drug plans are sold region-wide, meaning every plan counted here is available to anyone with Medicare living anywhere in the state.

The dip reflects two kinds of changes at once: a new insurer entering the Louisiana market and two insurers that offered stand-alone plans in 2026 stepping out for 2027. The net result is two fewer plan choices on the shelf.

Which insurers offer stand-alone Part D plans in Louisiana for 2027?

Four insurers will sell stand-alone Part D plans in Louisiana for 2027. Listed alphabetically, with the number of plans each will offer:

• Blue Cross and Blue Shield of IL, NM, OK, TX — 1 plan
• Humana — 3 plans
• UnitedHealthcare — 2 plans
• Wellcare — 2 plans

Blue Cross and Blue Shield of IL, NM, OK, TX is new to Louisiana's stand-alone Part D market for 2027. Two insurers that offered stand-alone drug plans in the state in 2026 — Aetna Medicare and HealthSpring — are not on the 2027 list. People currently enrolled in a plan that is leaving the market should watch for a written notice from their plan and compare their options on the Medicare Plan Finder before December 7, 2026.

What do the 2027 Part D out-of-pocket cap and deductible limit mean in Louisiana?

For 2027, the Part D out-of-pocket cap for covered drugs is $2,400, and no Part D plan — in Louisiana or anywhere else — may charge a deductible higher than $700. The cap is up from $2,100 in 2026.

The out-of-pocket cap is a ceiling: once what you have paid for covered prescriptions during the calendar year reaches $2,400, you pay nothing more for covered drugs for the rest of 2027. The $700 figure is the maximum deductible allowed; individual plans may set their deductible at that amount, lower, or at zero. To see what any particular Louisiana plan charges, use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE.

For reference, the Part D base beneficiary premium for 2027 is $41.33. That is a national figure used in the late-enrollment penalty calculation; the premium a specific plan charges is set plan by plan.

Which Louisiana Part D plans can someone with full Extra Help join at no premium in 2027?

Three stand-alone Part D plans in Louisiana will be available for 2027 with no monthly premium to people who qualify for full Extra Help — the federal low-income subsidy that helps with Part D costs. That is one more benchmark plan than in 2026, when two plans qualified.

Extra Help can lower premiums, deductibles and copays for prescription drugs. People can apply through the Social Security Administration at any time, and the Medicare Plan Finder flags which plans are benchmark plans for the Louisiana region.

How does stand-alone Part D compare with the drug coverage inside a Medicare Advantage plan in Louisiana?

Stand-alone Part D plans are sold separately and pair with Original Medicare; the 8 plans counted above are the stand-alone options available across Louisiana for 2027. Most Medicare Advantage plans, by contrast, bundle prescription drug coverage into one plan that also covers hospital and medical care.

The two paths are counted separately. A person generally picks one or the other: Original Medicare plus a stand-alone Part D plan (and often a Medigap policy), or a Medicare Advantage plan that includes drug coverage. Medicare.gov walks through the trade-offs.

How can I check a Louisiana plan's drug list and pharmacies before December 7?

The Medicare Plan Finder at medicare.gov is the official tool for checking any 2027 Louisiana Part D plan's formulary (drug list) and pharmacy network before the December 7, 2026 deadline. You can enter your ZIP code and your prescriptions and see how each plan handles them.

A few things worth confirming for each plan on your short list: whether every one of your drugs is on the formulary, what tier each drug sits on, whether the plan requires prior authorization or step therapy for any of them, and whether your usual pharmacy is in the plan's preferred network. The plan's own "Evidence of Coverage" and formulary documents, available from the insurer, give the full detail.

Where can Louisiana residents get free help with Part D for 2027?

Free, unbiased help is available from Medicare itself. You can call 1-800-MEDICARE (1-800-633-4227), available 24 hours a day, seven days a week, or use the Plan Finder and chat tools at medicare.gov.

A note on the broader 2027 picture: the Social Security Administration announced on October 14, 2026 a 3.6 percent cost-of-living adjustment for benefits payable beginning January 2027. The 2027 standard Part B premium and deductible, and the 2027 IRMAA income brackets, had not been announced as of this writing; CMS typically releases them in the fall.
