Medicare Part D

Before Your Next Refill in Westerly: How Part D Pharmacy Tiers Work

If you take a regular prescription and fill it at a pharmacy in downtown Westerly, then fill the same drug at a different counter across town or by mail, the price on the receipt can look different — sometimes noticeably so. That is not a mistake. It is how Part D pharmacy networks are built. Understanding the difference between a "preferred" pharmacy, a "standard" network pharmacy, and mail order can help you plan ahead and avoid surprises at pickup.

Before your next refill in Westerly, know how your Part D pharmacy network works

What a Part D pharmacy network actually is

Every Part D plan — whether it is a stand-alone drug plan or the drug coverage built into a Medicare Advantage plan — contracts with a set of pharmacies to fill prescriptions for its members. That contracted list is the plan's pharmacy network. If you use a pharmacy outside the network, the plan generally will not cover the fill at all, except in limited situations.

Inside the network, pharmacies are usually split into two levels:

• Preferred network pharmacies have agreed to lower negotiated pricing with the plan. Cost sharing for members is typically lower here.
• Standard network pharmacies are still in the network and still covered, but member cost sharing is often higher than at a preferred pharmacy.

Both are "in network." The plan just pays out — and asks you to pay in — differently at each one.

Why the same pill can cost more across town

The drug is the same. The dose is the same. So why does the price shift? A few reasons:

1. Negotiated rates differ. Preferred pharmacies accept lower reimbursement from the plan in exchange for steady volume. Standard pharmacies did not sign that same deal. 2. Your plan sets tiered cost sharing. Plans build their benefit so a Tier 1 generic at a preferred counter costs one amount, and the same Tier 1 generic at a standard counter costs another. 3. Mail order is priced separately. Many plans treat their mail-order pharmacy as its own category, often geared toward 90-day supplies of drugs you take every day.

None of this is illegal or hidden — it is baked into how Part D benefits are designed and filed with CMS. But it does mean the "cheapest" counter in Westerly for your specific drug depends on your specific plan.

Where mail order fits in

Mail-order pharmacies ship a supply — commonly 90 days — of maintenance medications directly to your home. For long-term drugs like those for blood pressure, cholesterol, or diabetes, mail order can be convenient and can carry different cost sharing than a retail visit.

Mail order is not a fit for everyone. If you need a prescription started quickly, if your dose changes often, or if you prefer to talk to a pharmacist face-to-face, a local counter may serve you better. And weather delays or mailbox security are real considerations in a coastal town like Westerly.

Plan availability in and around Westerly

Westerly is in Washington County, where a range of stand-alone Part D plans and Medicare Advantage plans with drug coverage are offered each year. Every plan sets its own network and its own preferred pharmacies, so two neighbors on the same street can have different "best" pharmacies simply because they are enrolled in different plans.

The specific list of preferred pharmacies also changes year to year. A pharmacy that was preferred for your plan in 2025 may be standard in 2026, or vice versa. That is one reason it is worth a fresh look each fall.

How to check before you fill

Before you drop off a new prescription — or if you have been filling the same drug for years and never questioned the price — take a few minutes to verify:

1. Log in to your plan's member portal or app, or call the member services number on the back of your card. Ask specifically: "Is this pharmacy preferred, standard, or out of network for my plan?" 2. Use Medicare's Plan Finder at medicare.gov. Enter your ZIP code and your drug list, and it will show cost estimates by pharmacy for the plans available in Washington County. 3. Ask about mail order for any drug you take every day. Your plan can tell you how a 90-day mail supply compares to a 30-day retail fill. 4. Recheck during the Annual Enrollment Period (October 15 – December 7), when plan designs and pharmacy networks reset for the new year.

What 2026 changes mean for your costs

A few program-wide facts are worth keeping in mind as you compare pharmacy options:

• The Part D out-of-pocket cap is $2,100 in 2026. Once your true out-of-pocket spending on covered drugs hits that number, you pay $0 for covered Part D drugs the rest of the year.
• The maximum Part D deductible is $615 in 2026. Plans can set a lower deductible, but not a higher one.
• The old coverage gap ("donut hole") is gone as of 2025. Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread your drug costs out over the calendar year in monthly bills, rather than paying large amounts at the counter. Enrollment is optional and free.
• IRMAA — higher Part B and Part D premiums for higher-income filers — begins above $109,000 in income for a single filer in 2026.
