The Biggest Medicare Changes for 2027 That You Should Know Before You Shop

If you're entering retirement or already enrolled in Medicare, 2027 brings important changes that could affect your health-care coverage and out-of-pocket costs. Understanding these updates now means you're better positioned when you shop for a plan during open enrollment. The following eight changes lay out what's shifting under Medicare and how you can prepare ahead of time to avoid money mistakes.

Medicare costs are going up

For 2027, Medicare Part B costs are projected to increase. The standard monthly premium was $202.90 in 2026 but is increasing to $209.50 in 2027, an increase of approximately 3.3%. The annual deductible is also projected to climb from $283 to $292, an increase of approximately 3.2%. Beneficiaries with higher incomes may pay more for their monthly Part B premiums

These cost increases reflect broader inflation in health care and pressures on Medicare funding. As a retiree, you'll want to build these higher costs into your budget now rather than be surprised later.

The growing national deficit could cause Medicare cuts

The One Big Beautiful Bill Act (OBBBA) raised concerns about potential Medicare spending cuts because of its projected impact on the federal deficit. The Congressional Budget Office (CBO) estimated that the legislation could add $3.4 trillion to the deficit between 2025 and 2034.

Under the Statutory Pay-As-You-Go (PAYGO) Act of 2010, that increase could have triggered automatic spending reductions, including an estimated $45 billion in Medicare cuts in fiscal year 2026 and $536 billion cumulatively from 2026 through 2034. These reductions would have affected payments to health care providers, potentially creating financial challenges for hospitals and other facilities serving Medicare beneficiaries.

However, Congress passed legislation in November 2025 that zeroed out the PAYGO scorecards, preventing those projected cuts from taking effect. Although the immediate threat of these automatic reductions was averted, federal budget pressures and future legislative decisions could still affect Medicare funding, provider reimbursement rates, and access to care.

You could face prior authorization requirements

Some services and procedures under Medicare, such as electrical nerve stimulator implants, skin and tissue substitutes, and knee arthroscopy, may require prior authorization in 2027 if you live in one of these six states: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. This means that before certain treatments or drugs are covered, you may need your Medicare plan's approval first.

Of those enrolled in Medicare Advantage plans, 99% already face prior authorization requirements for certain types of treatment.

For you, that means checking your plan's rules carefully and possibly changing plans if your current one becomes more restrictive.

Your Medicare Advantage plan may carry fewer benefits

If you're on a Medicare Advantage plan (Part C), be aware that in 2027, the supplemental benefits (so-called "extras" like meal delivery, transportation, or other non-medical perks) may be scaled back as new federal rules go into effect.

Before renewing your MA plan, compare the benefit list and don't assume all the extras you enjoyed will still be there.

You'll be auto-enrolled in the Medicare Prescription Payment Plan (MPPP)

In 2027, if you're covered under Part D for prescription drugs, you'll automatically be enrolled in the Medicare Prescription Payment Plan (MPPP), which lets you spread your drug costs across the year rather than pay large sums all at once.

This can help with budgeting, especially if you take several medications, though you'll still want to check how your monthly payment will be calculated. However, you have the option to opt out of this program if you'd like to.

There will be an out-of-pocket price cap for prescription drugs

Under Part D, your out-of-pocket maximum for covered prescription drugs will be capped at $2,400 in 2027. Once you hit that limit, you won't pay copays or coinsurance for covered drugs for the remainder of the year.

This cap functions as a protection mechanism, particularly useful if you manage chronic conditions or take high-cost medications.

The cost of insulin could drop

Good news if you use insulin: Medicare's insulin cost cap remains in place for 2027, but you could pay even less than $35 per month for certain covered prescriptions. Under Medicare Part D, your monthly cost for each covered insulin product is capped at the lesser of $35, 25% of its negotiated price, or 25% of its maximum fair price under Medicare's drug price negotiation program.

Under Part B, the $35 monthly cap remains in place for insulin used with covered durable insulin pumps. The Part B deductible does not apply to that insulin.

The price of certain prescription drugs should fall

Thanks to the Inflation Reduction Act of 2022, signed into law by President Biden, Medicare can negotiate prices directly with drug manufacturers for certain high-cost, brand-name medications that face no generic or biosimilar competition.

The first round of negotiated prices, covering 10 prescription drugs, took effect Jan. 1, 2026. A second round covering 15 additional medications is scheduled to take effect Jan. 1, 2027.

First 10 drugs — prices effective Jan. 1, 2026

• Eliquis
• Jardiance
• Xarelto
• Januvia
• Farxiga
• Entresto
• Enbrel
• Imbruvica
• Stelara
• Fiasp/NovoLog

Next 15 drugs — prices effective Jan. 1, 2027

• Ozempic / Rybelsus / Wegovy
• Trelegy Ellipta
• Xtandi
• Pomalyst
• Ofev
• Ibrance
• Linzess
• Calquence
• Austedo / Austedo XR
• Breo Ellipta
• Xifaxan
• Vraylar
• Tradjenta
• Janumet / Janumet XR
• Otezla / Otezla XR

The program is gradually expanding its reach, giving eligible seniors another opportunity to save on prescription drug costs.

If you're on certain specialty medications, ask your plan how these negotiations may affect your formulary or copays.

Bottom line

The 2027 changes under Medicare mean you cannot assume that your current plan's costs and benefits will simply roll over. Some expenses may rise, benefits may shift, and your plan choices could matter more than ever.

Be prepared to review your Medicare options in depth, compare next year's coverage carefully, and integrate these shifts into your overall retirement plan so you're not surprised come open-enrollment time.
