A $0 Medicare Advantage Premium Does Not Mean Costs Will Stay Flat in 2027

Medicare beneficiaries should pay close attention to several figures for 2027, including a higher prescription drug deductible and a higher ceiling on certain out-of-pocket expenses. Medicare Advantage plans can also adjust cost-sharing rules and extra benefits from one year to the next. A $0 premium means there is no added monthly premium for the plan, not that healthcare itself is free.

1. Prescription Drug Deductibles Are Rising

Prescription coverage shows how a plan can look affordable on paper while becoming more expensive at the pharmacy.

In 2027, Medicare Part D plans may charge a deductible as high as $700, up from $615 in 2026. Some plans still have no deductible, while others set a lower one. The exact amount depends on the plan, but the federal maximum is increasing.

For someone who fills several maintenance prescriptions each month, a deductible can mean paying more for covered drugs before the plan begins sharing the cost. A medication that once fit comfortably into the budget could require more cash early in the year.

The timing can be especially frustrating because prescription bills usually arrive alongside ordinary household expenses. Anyone comparing plans should look at the deductible, the price of each medication, and the pharmacy network. A $0 premium becomes less appealing if the medicines that matter most cost more.

2. The Prescription Drug Spending Cap Is Also Increasing

Medicare’s drug coverage includes an annual limit on out-of-pocket spending for covered Part D drugs. That limit rises from $2,100 in 2026 to $2,400 in 2027. A higher cap is not necessarily good news for every household, because it gives people with heavy prescription costs a larger threshold to cross before catastrophic coverage begins. Once beneficiaries reach that stage, Medicare Part D rules generally remove cost-sharing for covered Part D drugs for the rest of the year.

For someone who depends on an expensive specialty medication, this could mean paying more before that protection kicks in. Someone with minimal prescription spending may never come close to either limit.

The cap also does not apply to every medication. It covers only drugs included under Part D, and some payments are counted differently from others. Review the plan’s formulary, which lists covered medications, along with any restrictions or preferred pharmacy rules. A spending limit helps, but it does not make every prescription free.

3. Your Medical Out-of-Pocket Maximum Could Be Higher

Medicare Advantage plans must set a yearly limit on what members pay for covered Part A and Part B services. After a member reaches that limit, the plan pays the full cost of covered services for the rest of the year.

For 2027, the federal maximum for in-network out-of-pocket costs increases to $9,850, from $9,250 in 2026. Plans may choose lower limits, so not every member will face the highest amount. Still, the change matters during a costly medical year. Someone who needs surgery, rehabilitation, and repeated specialist visits could accumulate copays quickly. A higher limit can mean paying more before reaching that annual protection.

Check your plan’s actual limit instead of assuming the federal maximum applies. Also remember that this protection usually covers eligible medical services, not every healthcare expense. Premiums, prescription drug costs, and services the plan does not cover follow different rules.

4. Doctor Visits and Hospital Care May Cost More

A $0 monthly premium does not lock in the same price for every appointment. Medicare Advantage insurers set many of their own copayments, deductibles, and coinsurance amounts within Medicare’s rules, and those charges can change each January.

Pay close attention to specialist visits, diagnostic imaging, outpatient surgery, emergency care, and hospital admissions. A small increase in one copay may not seem like much, but several increases across commonly used services can add up over the course of the year.

For example, someone who sees a specialist every few weeks may notice even a modest increase. Another person may rarely visit a doctor but face higher costs after an unexpected hospital stay. The least expensive plan on paper may not be the least expensive plan for either person.

Your plan’s Annual Notice of Change should explain the updated costs for the coming year. Compare those numbers with the services you actually use, not just the premium advertised in marketing materials.

5. Dental, Vision, and Other Extras May Be Reduced

Many Medicare Advantage plans promote extras beyond traditional Medicare coverage, such as dental allowances, routine vision care, hearing benefits, and over-the-counter product allowances. Those extras can make a plan seem especially valuable. But insurers can revise covered benefits, allowances, provider networks, and eligibility rules from year to year. A benefit that looks generous in one year may be worth less in the next.

Dental coverage deserves particular attention. An advertised allowance may still come with annual caps, covered-service limits, or network restrictions. A smaller allowance could leave you paying more for a crown or another costly procedure. The same applies to hearing aids and other benefits with coverage limits.

Look at the actual benefit details instead of relying on a headline dollar amount. A large allowance does little good if your preferred dentist is out of network or your treatment falls outside the plan’s rules.

Review Your 2027 Plan Carefully

Begin with the Annual Notice of Change your insurer sends each fall. Compare the old and new costs, then review the prescriptions, doctors, hospitals, and extra benefits that matter most to your household. Medicare’s official plan comparison tool at Medicare.gov can help you evaluate available options during Open Enrollment. You can also use a service like Chapter to narrow down the plan that best fits your needs.

One more reminder: a $0 Medicare Advantage premium does not replace your regular Medicare Part B premium. Most beneficiaries still have to pay it, although some plans help cover part of that cost.

A familiar plan may still be the right choice for 2027. Just make sure the familiar price tag reflects what you will actually pay for care, not only what you will pay to keep the coverage.
