Open enrollment: Oct 15 to Dec 7, 2026

Your plan renews on its own. Its costs don’t stay the same.

What’s different for 2027, and the six things to check before the deadline.

**Dec 7**Last day to switch Medicare Advantage or Part D plans for 2027. Changes
take effect January 1.

**Key takeaways**

✔ The Part D out-of-pocket cap rises to $2,400 in 2027, and plans can charge a drug
deductible of up to $700.

✔ Negotiated Medicare prices take effect for 15 more drugs, including Ozempic, Wegovy
and Rybelsus.

✔ Some Medicare Advantage plans are leaving areas or trimming extras. Read your 
Annual Notice of Change.

✔ If you do nothing, you usually stay in your current plan, even if it changed.

Every fall, people with Medicare get seven weeks to change how they get their coverage
for the coming year. Open enrollment runs October 15 to December 7, and any change
you make starts January 1.

Most people do nothing, and their plan renews. That’s fine if the plan still fits.
But plans change their premiums, drug lists, networks and extras every year, and
2027 has more moving parts than usual. Here’s what’s new, and how to check whether
your plan still works for you.

## What you can change during open enrollment

 * Switch from Original Medicare to a Medicare Advantage plan, or from Medicare 
   Advantage back to Original Medicare
 * Switch from one Medicare Advantage plan to another
 * Join, switch or drop a Part D prescription drug plan

Medigap policies aren’t part of open enrollment. You can apply for one any time,
but outside your initial Medigap window insurers in most states can ask health questions.
If you’re thinking about leaving Medicare Advantage for Original Medicare, check
whether you can get a Medigap policy _before_ you switch.

## What’s changing for 2027

| Item | 2026 | 2027 | 
| Part D out-of-pocket cap | $2,100 | $2,400 | 
| Maximum Part D deductible | $615 | $700 | 
| National base beneficiary premium (Part D) | $38.99 | $41.33 | 
| Medicare Advantage in-network out-of-pocket limit (maximum) | $9,250 | $9,850 | 
| Part B standard premium | $202.90 | Not yet announced (projected about $209.50) |

### Drug costs: a higher cap, and a higher deductible

Since 2025, Part D has had a yearly cap on what you pay out of pocket for covered
drugs. In 2027 that cap rises to $2,400. Once you reach it, you pay nothing more
for covered Part D drugs for the rest of the year. Plans can also charge a deductible
of up to $700 before coverage starts, though many charge less or none for cheaper
drug tiers.

If you take expensive medications, you may hit the cap early in the year. The Medicare
Prescription Payment Plan lets you spread those costs into monthly payments instead
of paying a large amount at the pharmacy in January. Ask your plan how to sign up
for 2027.

### Premiums: a federal discount is ending

For 2025 and 2026, a temporary CMS program reduced premiums for many stand-alone
Part D plans. CMS decided not to extend it, so some drug plan premiums may rise 
for 2027. This is exactly why comparing matters: a plan that was the cheapest in
2026 may not be in 2027.

### Lower prices for 15 more drugs

Medicare-negotiated prices take effect January 1, 2027, for a second group of 15
drugs. The list includes Ozempic, Rybelsus and Wegovy (a negotiated price of $274
for a 30-day supply), Trelegy Ellipta, Breo Ellipta, Linzess, Xifaxan, Tradjenta,
Janumet and Otezla, among others. What you actually pay still depends on your plan’s
tiers and deductible, but if you take one of these drugs, run your plan comparison
again.

### Medicare Advantage: higher caps and some pullbacks

CMS raised the maximum in-network out-of-pocket limit Medicare Advantage plans can
set to $9,850 for 2027. Some insurers are also leaving certain counties or cutting
back extras like dental allowances. If your plan won’t be offered in your area next
year, you’ll get a letter, and you get a Special Enrollment Period to choose new
coverage.

### Telehealth stays available

Expanded Medicare telehealth flexibilities, including visits from home, have been
extended through December 31, 2027.

## Your pre-deadline checklist

**1. Read your Annual Notice of Change**
Plans had to mail it by September 30. Look
for changes to the premium, deductible, copays, drug tiers and networks. Can’t find
it? Your plan’s website or member services line can resend it.

**2. Check every prescription**
Confirm each drug is still on the formulary, which
tier it’s on, and whether it now needs prior authorization or step therapy. Formularies
change every year.

**3. Confirm your doctors, hospitals and pharmacy**
If you’re in Medicare Advantage,
check that your doctors and preferred hospital are in network for 2027. Check whether
your pharmacy is still “preferred,” which can lower what you pay.

**4. Add up the total yearly cost**
Premiums, plus the deductible, plus expected
copays for your drugs and visits. Then look at the out-of-pocket maximum for a bad
year. Don’t forget your Part B premium, which you pay with any option.

**5. Look at extras with a critical eye**
Dental, vision and hearing benefits can
be useful, but they often have low annual caps or limited networks. Don’t let a 
gym membership decide your medical coverage.

**6. Compare side by side on Medicare.gov**
The Plan Finder lets you enter your 
drugs and pharmacies and see estimated yearly costs for every plan in your ZIP code.

## A simple way to compare two plans

Say Plan A has a $0 premium, a $5,900 out-of-pocket cap and $45 specialist copays,
and Plan B costs $39 a month with a $3,900 cap and $30 specialist copays. In a quiet
year with eight specialist visits, Plan A costs $360 and Plan B costs $708 ($468
in premiums plus $240 in copays). In a year with a hospital stay that hits both 
caps, Plan A costs $5,900 and Plan B costs $4,368. Neither is “better” in every 
year. The point is to know which risk you’re choosing.

_Example figures are hypothetical. Your plans’ actual costs will differ._

## What if you miss December 7?

 * **Medicare Advantage Open Enrollment, January 1 to March 31:** if you’re in a
   Medicare Advantage plan, you can switch to a different Medicare Advantage plan
   or go back to Original Medicare (and join a Part D plan) once.
 * **Special Enrollment Periods:** moving, losing other coverage, moving into or
   out of a nursing home, or your plan leaving your area can all open a window.
 * **5-star plans:** you can switch to a plan rated 5 stars once during the year,
   if one is available where you live.
 * **Extra Help or Medicaid:** people who qualify have more chances to change drug
   plans.

## Watch out for open enrollment scams

![Older couple comparing plans on a computer at home](https://fantasyfrontierfun.

 * Medicare will not call you to sell a plan or ask for your Medicare number.
 * Agents and plans aren’t allowed to make unsolicited “cold” calls to sell coverage.
 * Be wary of TV ads promising “extra money back” on your Social Security. Ask exactly
   which plans offer it and what you give up.
 * If in doubt, hang up and call 1-800-MEDICARE yourself.

## Quick answers

### Do I have to re-enroll in Medicare every year?

No. If you do nothing, you usually stay in your current plan. You only need to act
if you want to change, or if your plan is ending.

### When will the 2027 Part B premium be announced?

CMS usually announces it in mid-November. The Medicare Trustees projected about 
$209.50 a month, up from $202.90 in 2026, but the official figure may differ.

### If I switch plans, do I have to cancel my old one?

Usually not. Joining a new Medicare Advantage or Part D plan generally ends your
old one automatically when the new one starts. Leaving Medicare Advantage for Original
Medicare works the same way once you join a Part D plan.

### Where can I get free help comparing plans?

Your State Health Insurance Assistance Program (SHIP) offers free, unbiased counseling.
Find yours at shiphelp.org or call 1-800-MEDICARE.
