The main Medicare drug plan providers in Alabama
The companies that offer Part D prescription drug plans in Alabama change each year, but the largest providers are typically UnitedHealthcare, Humana, Aetna, CVS Caremark, and Walgreens. These are not the only options — smaller regional plans also operate in the state. The exact list of available plans, which companies offer them, and which pharmacies they work with all shift on January 1 each year when the new plan year begins.
You can see the current list of Part D plans available to you by visiting Medicare.gov and using their Plan Finder tool. You enter your zip code, the medications you take, and the pharmacies you prefer, and the tool shows you every plan offered in your area along with the company name, monthly premium, and what you will pay out of pocket for your specific drugs.
The Plan Finder is the only way to know for certain which plans are actually available to you right now, because availability varies by county within Alabama. A plan offered in Jefferson County may not be offered in Baldwin County. Calling the companies directly can be slower — they may not have your county's information readily available, and you will still need to check Medicare.gov to compare prices.
Key Takeaways
- UnitedHealthcare, Humana, Aetna, CVS Caremark, and Walgreens are the largest Part D providers in Alabama, but the complete list changes yearly.
- Medicare.gov's Plan Finder tool shows you every plan available in your specific county, along with the monthly cost and what you will pay for each of your medications.
- The same company may offer multiple Part D plans with different costs and pharmacy networks, so comparing plans matters even if you stay with the same insurer.
- You can change Part D plans once per year during the annual enrollment period from October 15 to December 7, or if you have a may have access to life event.
How to find plans available in your county
Start at Medicare.gov and select "Find Care Providers & Suppliers" or go directly to the Plan Finder. You will need your Medicare number, which is on your Medicare card. Enter your zip code, and the tool will show all Part D plans available in your county. You can filter by monthly premium, by pharmacy network, or by specific medications you take.
If you use a particular pharmacy — whether that is a local independent pharmacy, a chain like Walgreens or CVS, or a mail-order service — check whether each plan you are considering includes it in their network. Some plans work with all major chains but exclude smaller pharmacies. Others have limited networks. The pharmacy you use can affect your total out-of-pocket cost as much as the plan itself.
Once you have narrowed down to two or three plans, compare not just the monthly premium but also the deductible, copays for your specific drugs, and whether any of your medications fall into a coverage gap. The cheapest monthly premium is not always the cheapest plan overall.
What to know about plan changes and timing
If you are already enrolled in a Part D plan and want to switch, you can do so during the annual enrollment period, which runs from October 15 to December 7 each year. Any new plan you choose takes effect on January 1. This is also when all the plan details — premiums, copays, formularies, and pharmacy networks — change for the coming year.
If you miss the October 15 to December 7 window, you generally cannot change plans until the next year's enrollment period, unless you experience a may have access to life event such as losing employer coverage, moving out of state, or becoming may be able to access for Medicaid. Some people also may have access to for a Special Enrollment Period if they are in a plan that is being discontinued.
If you are new to Medicare or turning 65, you have a one-time Initial Enrollment Period to choose a Part D plan. This period is seven months long, centered on the month you turn 65. If you do not choose a plan during this window, you may owe a late enrollment penalty for as long as you have Medicare.
Understanding formularies and coverage tiers
Each Part D plan has a formulary — a list of medications the plan covers and how much you pay for each one. Medications are organized into tiers, usually ranging from tier 1 (lowest cost, often generic drugs) to tier 5 (highest cost, often brand-name drugs with no generic equivalent). Your copay or coinsurance depends on which tier your medication is on.
A medication you take might be on tier 1 in one plan and tier 3 in another, which can mean a difference of several dollars per prescription. This is why entering your actual medications into the Plan Finder matters — it shows you the real cost you will pay, not just the plan's general structure.
If your doctor prescribes a medication that is not on a plan's formulary, you can ask the plan for an exception. The plan may agree to cover it anyway, or it may suggest a similar drug that is covered. This process takes time, so if you are switching plans and take medications that are not commonly covered, call the new plan before your coverage starts to ask about exceptions.
The coverage gap and how it affects your costs
Part D plans have a coverage gap, sometimes called the "donut hole," that kicks in after you and your plan have spent a certain amount on your medications in a calendar year. Once you enter the gap, you pay a higher percentage of your drug costs until you reach catastrophic coverage, where your costs drop again. The exact amounts and percentages change each year.
Not all medications cost the same in the gap. Generic drugs are typically cheaper than brand-name drugs during this period. If you take expensive brand-name medications, the gap can significantly increase your annual costs. Some plans offer better gap coverage than others, which is another reason to compare plans carefully if you take high-cost drugs.
If you may have access to for Extra Help (a federal program for people with limited income), the coverage gap may be reduced or eliminated for you. You can check whether you may have access to by visiting Medicare.gov or calling 1-800-MEDICARE.
Contacting Part D providers directly
If you want to speak with a representative from a specific company, here are the main providers and their customer service numbers. These numbers are current but may change, so verify them on Medicare.gov or your plan documents before calling.
UnitedHealthcare, Humana, Aetna, CVS Caremark, and Walgreens all have dedicated Part D customer service lines. When you call, have your Medicare number ready. Representatives can answer questions about whether a specific medication is covered, what your copay will be, and whether a particular pharmacy is in the network. However, they cannot tell you whether a plan is available in your county — you still need to check Medicare.gov for that.
If you need help comparing plans or have questions about how Part D works, you can also call 1-800-MEDICARE to speak with a Medicare counselor. This service is free and available 24 hours a day, 7 days a week.
What happens if your plan is discontinued
Occasionally, an insurance company stops offering a particular Part D plan in Alabama or in your specific county. If this happens to you, Medicare will send you a notice at least 30 days before the plan ends. You will then have the option to switch to a different plan without waiting for the annual enrollment period.
When a plan is discontinued, Medicare automatically assigns you to another plan if you do not choose one yourself. The automatic assignment is usually to a plan offered by the same company, but it may not be the plan that best fits your needs. It is better to actively choose a new plan using the Plan Finder rather than accepting the automatic assignment.
Frequently Asked Questions
Can I switch Part D plans in the middle of the year?
No, unless you have a may have access to life event such as losing employer coverage, moving, or becoming may be able to access for Medicaid. The annual enrollment period from October 15 to December 7 is the standard time to change plans. If your current plan is being discontinued, Medicare will allow you to switch outside this window.
What if my doctor prescribes a drug that is not on my plan's formulary?
Contact your Part D plan and ask for a formulary exception. The plan may cover the medication anyway, or it may suggest a covered alternative. This process can take several days, so contact the plan as soon as you know you will need the medication. Your doctor can also submit a request on your behalf.
Do all Part D plans in Alabama use the same pharmacies?
No. Each plan has its own pharmacy network. Some plans work with all major chains, while others have limited networks. Before enrolling in a plan, check whether your preferred pharmacy is included. You can do this on Medicare.gov or by calling the plan directly.
What is the difference between a Part D plan and a Medicare Advantage plan that includes drug coverage?

Medicare Advantage plans are an alternative to Original Medicare and usually include drug coverage as part of the plan. If you have Original Medicare, you need Part D. If you have Medicare Advantage, drug coverage is typically included, though you can sometimes add a separate Part D plan.
