What to Review Before Your Medicare Plan’s 2027 Pharmacy Changes

Quick Read

• Medicare Part D and Medicare Advantage plans may change their pharmacy networks for 2027, which could affect where prescriptions are filled and how much you pay.
• A pharmacy can stay in your plan’s network but lose preferred status, which may make the same medication more expensive next year.
• Open Enrollment ends on December 7, leaving beneficiaries a short window to compare plans before coverage begins on January 1.
• If you need help comparing plans, Chapter provides free, no-pressure Medicare guidance to review prescription coverage, pharmacy networks, and possible savings. Call (864) 668-3280.

Your pharmacist may know your name, understand your medication history, and have helped manage your prescriptions for years. Then a notice from your Medicare plan arrives saying your pharmacy setup could change in 2027.

That can mean the pharmacy you depend on may no longer be covered at the same price, or it could leave your plan’s network entirely. For retirees taking several prescriptions, that shift may lead to higher monthly costs, longer trips to another pharmacy, or trouble getting refills.

With Open Enrollment ending soon, beneficiaries have only a limited period to review coverage for the coming year. Even if your monthly premium does not change, your total prescription costs still might.

Here’s what to check before deciding whether to keep your current Medicare plan or switch for 2027.

Your Pharmacy May Stay in Network but Become More Expensive

Medicare Part D plans contract with participating pharmacies, and those arrangements can change from year to year. Medicare explains that some plans separate pharmacies into preferred and standard in-network categories, with preferred locations usually offering lower out-of-pocket costs for covered prescriptions. So a pharmacy you have used for years may still be in network but cost more if its preferred status changes.

For instance, if a prescription costs $8 at a preferred pharmacy and $18 at a standard one, that difference adds up to $120 a year for one monthly medication. Before renewing, confirm whether your pharmacy will be preferred, standard, or out of network in 2027 instead of assuming that insurance coverage automatically means the lowest price.

Your Annual Notice of Change May Hold Other Surprises

Medicare Advantage and standalone Part D plans send an Annual Notice of Change, or ANOC, each fall to outline upcoming changes in coverage and costs. Medicare’s guidance says beneficiaries should receive this notice in September and review it before deciding on next year’s coverage. The document may describe changes in premiums, deductibles, benefits, and prescription drug coverage, though you may still need the plan’s pharmacy directory to confirm specific locations.

If your current pharmacy is not listed, or if its status is unclear, call the plan using the number on your membership card and ask for confirmation for 2027. Keep a record of the conversation, including the representative’s name and any reference number, especially if you rely on that information to make your choice.

Check Every Medication Before You Pick a Plan

A familiar pharmacy is only one part of the equation. Medicare drug plans can also change formularies, drug tiers, prior authorization rules, step therapy requirements, and quantity limits, all of which may affect how much you pay or how easily you get medication. The Medicare Plan Finder lets beneficiaries enter prescriptions and compare estimated costs across plans and pharmacies.

Include each medication’s exact name, dosage, quantity, and refill frequency, because even small differences can alter the estimate. Someone taking five or six medications may find that a plan with a slightly higher premium ends up costing less overall because its prescription coverage fits their needs better.

Lower Premiums Do Not Always Mean Lower Drug Costs

The Centers for Medicare & Medicaid Services projects that average Medicare Advantage premiums will fall from $14.37 in 2026 to $12 in 2027, while average standalone Part D premiums will rise from $35.09 to about $36. But national averages do not determine what one person will actually pay for prescriptions at a specific pharmacy. A plan with a lower premium may still have higher copays, a less convenient pharmacy network, or tighter restrictions on the medicines you use regularly.

For 2027, the annual Part D out-of-pocket spending threshold is $2,400 for covered drugs, but premiums and some other expenses do not count toward that limit. Compare total estimated yearly costs instead of relying on one advertised number.

Mail-Order Pharmacies Are Not Always the Cheapest Choice

Some Medicare plans encourage the use of mail-order pharmacies for regular medications, sometimes offering 60-day or 90-day supplies. Home delivery can be especially useful for older adults who no longer drive, live in rural areas, or have trouble getting to a pharmacy.

Still, Medicare guidance says mail-order is an option, not a guarantee of lower costs, and the financial benefit depends on the plan and the medication. Shipping timing, temperature-sensitive prescriptions, emergency refills, and customer service also matter, especially for medications that cannot be interrupted. Before moving prescriptions, compare the real price of a 90-day mail-order supply with the cost of the same medication from a preferred local pharmacy.

Switching Prescriptions May Take Advance Planning

If your longtime pharmacy is no longer in your plan’s network, transferring prescriptions may take more preparation than expected. Many routine prescriptions can be moved between pharmacies, but controlled substances and some specialty medications have extra federal or state rules that can limit how transfers work. Patients using specialty medications may also have to use designated pharmacies, which can create complications when a network changes.

Contact your current pharmacy, the pharmacy you may switch to, and your prescribing clinician before January to find out whether new prescriptions, prior authorizations, or other arrangements will be needed. Planning ahead can reduce the chance of running out of essential medication during the shift to your 2027 coverage.

The Deadline Most Beneficiaries Need to Remember

Medicare’s annual Open Enrollment Period runs from October 15 through December 7, giving eligible beneficiaries a chance to change Medicare Advantage and Part D coverage for the following year. Medicare says changes made during this window generally begin on January 1, meaning your 2027 pharmacy arrangements can take effect right after the holidays. People who do not act usually remain in their current plan if it continues, even though the plan’s benefits, costs, and pharmacy network may change.

Some people qualify for Special Enrollment Periods, and Medicare Advantage members have a separate enrollment window later in the year, but those exceptions do not apply to everyone. If your prescriptions or preferred pharmacy are changing, finish your comparison and any needed enrollment before December 7 instead of assuming you can make the same move later.

Help With Prescription Costs May Be Available

Older adults with limited income and resources may qualify for Medicare’s Extra Help program, which lowers certain Part D prescription drug costs. The Social Security Administration provides eligibility details and applications for beneficiaries who need help paying premiums, deductibles, and prescription cost sharing. Some beneficiaries may also qualify for Medicare Savings Programs, which can help with certain Medicare expenses and may automatically qualify them for Extra Help.

These programs can make a meaningful difference for retirees managing several prescriptions, especially when household income has changed after retirement or the death of a spouse. Before assuming you do not qualify, review the current rules or contact Social Security or your State Health Insurance Assistance Program for guidance.

It Pays to Take a Second Look at 2027 Pharmacy Costs

A change in your pharmacy network may seem minor until you realize the same prescriptions will cost more or require a different location. Reviewing your Annual Notice of Change, checking preferred pharmacy status, and comparing each medication can help uncover expensive surprises before the new plan year starts. The December 7 deadline makes this especially important for beneficiaries who rely on multiple prescriptions or have longstanding relationships with local pharmacists. Free resources such as Medicare.gov, State Health Insurance Assistance Programs, and Medicare plan advisors can help you review your options without rushing. Taking time to compare coverage now could protect both your medication routine and your retirement budget throughout 2027.
