Medicare Advantage premiums are projected to drop for 2027, and open enrollment, which kicks off October 15, is your yearly shot at landing a plan that fits your health and your budget even better. Set aside a few evenings before December 7, and you could start the new year paying less for the doctors and prescriptions you already count on.

Mark Your Calendar: October 15 to December 7

Open enrollment for 2027 coverage starts October 15, 2026, and closes December 7. That’s eight weeks. Whatever you choose takes effect January 1, 2027, and your plan generally has to receive the request by the deadline, so a form dropped in the mail on December 6 is cutting it far too close.

During those weeks you can move from one Medicare Advantage plan to another, leave Advantage for Original Medicare, join Advantage for the first time, or swap Part D drug plans. You can also do nothing. Plenty of people take that last route by default, and it’s usually the one that costs them.

Miss the window? A smaller second chance exists. From January 1 through March 31, 2027, anyone already enrolled in a Medicare Advantage plan gets exactly one switch, either to a different Advantage plan or back to Original Medicare with a standalone drug plan. It only runs in one direction, though. Someone on Original Medicare can’t use that spring window to join an Advantage plan. Medicare’s open enrollment page explains the separate rules that apply when you move, turn 65, or lose job-based coverage.

Open the Letter Nobody Reads

Every Medicare Advantage plan has to mail its members an Annual Notice of Change by September 30. Most of those envelopes go straight into a drawer.

Don’t let yours. The ANOC is a plain side-by-side of this year against next: premium, deductible, copays for a specialist visit or an MRI, the drug list, and any doctors or hospitals leaving the network. It’s dull reading. It’s also the only place your insurer is required to spell out, in writing, what’s about to get worse.

The national averages look calm this year. CMS projects the typical Advantage premium will drop from $14.37 a month to about $12, and around 80% of members can keep their current plan at the same or a lower premium. That still leaves millions of people whose plan is getting pricier or disappearing, and a flat premium can hide a higher copay, a tighter drug list, or a hospital system that walked away from the network over the summer. Got a nonrenewal notice instead? Your plan is ending, and you’ll want a replacement lined up well before December 7.

Your Prescriptions Deserve the Most Attention

Drug coverage is where plans quietly shift the most money around, and 2027 brings two federal changes worth knowing. The annual cap on what you pay for covered Part D drugs rises from $2,100 to $2,400, and the maximum standard deductible climbs from $615 to $700, both set in the final 2027 rate announcement CMS released in April. Insulin stays capped at $35 a month per prescription.

What does that look like in real life? Say you take one brand-name medication that costs about $600 a month, and your plan follows the standard benefit design. In January you’d pay the full $600. February brings the last $100 of the deductible plus 25% of the remaining $500, or $225. From March on, you’re paying 25% of $600, which works out to $150 a month. Add it up and you’d spend roughly $2,325 for the year, just under the $2,400 ceiling, with the heaviest hit landing in the first two months.

That front-loading catches people off guard. A $600 pharmacy bill in January feels very different from $150 in June, even though both are perfectly normal under the rules. (Medicare’s Prescription Payment Plan lets you spread those costs into monthly bills instead, which doesn’t lower the total but can make January a lot less painful.)

Plenty of Advantage plans don’t use the standard design at all. Some skip the deductible on cheaper generics, some charge flat copays, and some put a drug you’ve taken for years on a higher tier starting January 1. The only way to know is to check each plan against your actual list.

So write the list down. Every medication, the dose, and how often you fill it. Then plug it into Medicare’s Plan Compare tool along with the pharmacies you use, and sort the results by estimated total annual cost rather than premium. Watch for the little flags next to each drug: prior authorization, step therapy, quantity limits. Any one of those can mean a phone call, a delay, or a denial before you get your refill.

One trap worth avoiding. Joining a standalone Part D plan while you’re in an Advantage plan that already covers drugs will generally kick you out of the Advantage plan and back to Original Medicare. People do this by accident every year.

Call Your Doctors Before You Trust the Directory

Online provider directories are notoriously out of date. Before you commit to any plan, phone your primary care office, each specialist, and the hospital you’d want to end up in, and ask a precise question: do you accept this exact plan, by name, for 2027? One insurer can sell five or six plans in the same county with completely different networks, so “we take Humana” or “we take UnitedHealthcare” isn’t an answer.

Plan type matters here too. HMOs usually cover only in-network care outside of emergencies and often require a referral before you see a specialist. PPOs pay something toward out-of-network visits, though you’ll pay more for them, and an out-of-network doctor can still decline to see you.

Split the year between two states? Have a cardiologist two counties over? Ask how routine and follow-up care works when you’re away, because many Advantage networks are tightly local. Keeping one particular doctor can be worth more than any gym membership or grocery card a plan dangles in front of you.

Price Out Your Worst Year, Not Your Average One

A $0 premium is the most effective sales tool in Medicare. It’s also the least useful number on the page.

The figure that protects you is the plan’s maximum out-of-pocket limit, the most you’d pay in a year for covered in-network medical care (drugs are tracked separately). For 2027, CMS lets plans set that limit as high as $9,850 in-network, up from $9,250, and as high as $14,800 for PPOs that combine in- and out-of-network care. Many plans come in well under the ceiling, but some go right up to it.

Try this comparison. Plan A charges no premium and has an $8,900 limit. Plan B costs $45 a month, or $540 a year, with a $4,500 limit. In a quiet year with a few checkups, Plan A saves you about $540. Now picture a knee replacement, a hospital stay, and twelve weeks of physical therapy. Plan A could cost you up to $8,900, while Plan B tops out near $5,040 including premiums. Which year are you budgeting for?

There’s no wrong answer, only an honest one about your health and your savings. Keep paying your Part B premium either way; CMS typically announces the 2027 amount in the fall.

Weighing a move back to Original Medicare? It has no annual cap on its own, which is why most people pair it with a Medigap policy. Be careful, though. Outside your initial enrollment window, Medigap insurers in many states can ask health questions and turn you down, so line up a Medigap approval before you give up an Advantage plan.

The Fine Print on Dental, Vision, and Hearing

Extras are real perks when you actually use them. A $1,500 dental allowance might cover two crowns, or it might reimburse cleanings only, through one vendor, after a six-month wait. Hearing aid benefits often require a plan-approved provider. Check the Evidence of Coverage, and treat extras as a tiebreaker after doctors, drugs, and total costs have done their work.

Get Free Help, Then Lock It In

Not sure you trust your own spreadsheet? Every state runs a State Health Insurance Assistance Program staffed by trained counselors who don’t sell insurance and don’t earn commissions. A SHIP counselor will sit down with your ANOC and your drug list, walk through Plan Compare with you, and flag problems you might miss, especially if you’re juggling Medicaid, retiree coverage, or a possible move back to Original Medicare. You can find your local SHIP office online or by phone. Appointments fill up fast after Halloween, so book early.

Once you’ve chosen, enroll through Medicare.gov, by calling 1-800-MEDICARE, or directly with the plan. Save the confirmation number. Screenshot it, even. A welcome packet and a new member card should show up before January 1; if December rolls around and you’ve heard nothing, call the plan.

Staying put is a legitimate choice, too. Just make it on purpose, after you’ve read the notice, checked your drugs, and called your doctors. That’s a few evenings of work against a full year of coverage.
