Only 3 Medicare Plans Worth Enrolling In 2026 (Plus The 2027 Changes Hitting Right Now)

Only 3 Medicare plan setups are worth a serious look in 2026: Original Medicare with Medigap Plan G, a Medicare Advantage plan with a strong network, and Original Medicare with a stand-alone drug plan. With open enrollment ending December 7, here is who each fits and the 2027 changes to know.

First, a Timing Alert

The headline says 2026, but the clock that matters now is the fall enrollment window. Medicare’s Fall Open Enrollment runs October 15 through December 7, and any changes beneficiaries make take effect January 1, 2027. So if you’re choosing a plan this month, you’re really choosing for 2027. “Only 3” is also a simplification. These are three setups that cover most people’s needs, and the right one depends on your health, budget, and doctors. healthjournalism

Plan Setup #1: Original Medicare + Medigap Plan G + a Drug Plan

Why it makes the list: Predictability. Original Medicare has no cap on what you might pay, but a Medigap policy fills most of the gaps. As Kiplinger notes, due to the phasing out of the popular Medigap Plan F, Plan G is now the plan of choice for many. A podcast explainer describes it as a predictable shield: you pay the premium up front, but your risks are capped. kiplingerbuzzsprout

Best for: People who want to see any doctor who accepts Medicare, travel often, or want to avoid surprise bills.

Watch out for:

  • Rising premiums. A national sampling of Medigap plans showed double-digit percentage premium increases this year, with another round possible for 2027. healthjournalism
  • Underwriting. Outside your initial enrollment window, many states let insurers review your health before approving you.
  • You still need a drug plan. Medigap doesn’t include prescription coverage.
  • A cheaper option. Kiplinger says Plan K and Plan L are cheaper than other Medigap policies and have an out-of-pocket limit. kiplinger

Plan Setup #2: A Medicare Advantage Plan With a Strong Network

Why it makes the list: Low premiums and extra benefits. WTOP reports that the average premium for a Medicare Advantage plan in 2026 is $14 per month, according to the Centers for Medicare & Medicaid Services. Many plans bundle drug coverage and extras such as dental or vision. wtop

The catch: A low premium isn’t the whole story. Medicare Advantage has an out-of-pocket maximum, but the 2026 maximum for in-network care is $9,250. Original Medicare has no cap, but MA plans do, and their maximums only include costs for Part A and Part B services. The podcast analogy puts it bluntly: a $0 premium can be an illusion of savings if you get seriously ill. Navigating Medicare Deductibles and Premiums in 2026 +2

Best for: Healthy people on a budget whose doctors and hospitals are in the plan’s network, and who are comfortable with rules such as prior authorization.

Watch out for:

  • Plan exits and benefit cuts. A consumer advocate warned that some Medicare Advantage plans are pulling out of specific geographic areas and scaling back benefits, such as dental coverage, while potentially increasing cost-sharing. wafb
  • Medigap lock-out. You’re prohibited from buying a Medigap plan while enrolled in an MA plan, and switching back may mean underwriting later. kiplinger
  • A safety net. If your plan is leaving the market, you get guaranteed-issue access to most Medigap plans in your area if you switch to original Medicare. healthjournalism

Plan Setup #3: Original Medicare + a Stand-Alone Drug Plan (No Supplement)

Why it makes the list: Flexibility and low fixed cost. You’d pay the Part B premium, which is $202.90 per month in 2026, plus a Part D plan, and skip the Medigap premium. That can be a fit for people in good health who want to keep any doctor and are willing to accept some risk. socialworkers

The catch: Without Medigap or other coverage, you’re responsible for the Part A deductible ($1,736 per benefit period in 2026) and Part B cost-sharing, with no annual cap on Original Medicare. Many people in this setup pair it with retiree, employer, or Medicaid coverage. wtop

Don’t skip the drug plan. Kiplinger’s advice: consider getting a drug plan even if you don’t take many drugs, since a low-premium plan avoids the late enrollment penalty. kiplinger

The 2027 Changes You Can’t Ignore

  • Part B premium. The standard Part B premium is projected to rise from $202.90 to about $209.50 a month in 2027. healthjournalism
  • Part D cap. The cap on annual out-of-pocket Part D spending will increase to $2,400, up from $2,100 in 2026, and the standard deductible will increase from $615 to $700. wafbwafb
  • Subsidies. The temporary Part D premium subsidy will also end early. wafb
  • Drug tiers. A drug moving to a higher tier means bigger out-of-pocket costs even though the $2,400 cap still applies. healthjournalism

A Quick Decision Guide

  • You see lots of specialists, travel, or want predictability: consider Setup #1.
  • You’re healthy, on a budget, and your doctors are in-network: consider Setup #2.
  • You have other coverage or want the lowest fixed premium and accept risk: consider Setup #3.
  • Taking costly drugs: compare each plan’s drug formulary closely. The Part D cap protects you, but tiers and pharmacies matter.

6 Steps Before December 7

  1. Read your Annual Notice of Change. It lists next year’s premiums, networks, and drug coverage.
  2. Check your doctors and hospitals against each plan’s network.
  3. Check your prescriptions against each plan’s formulary and tiers.
  4. Compare total yearly cost, not just the monthly premium.
  5. Ask about Medigap rules in your state before leaving a supplement.
  6. Get free help. Use Medicare.gov’s Plan Finder, call 1-800-MEDICARE, or contact your State Health Insurance Assistance Program (SHIP).

The Bottom Line

 

The “only 3 plans” idea is really three paths: Original Medicare with Medigap G for predictability, a well-chosen Medicare Advantage plan for low upfront cost, or Original Medicare with a drug plan for a lean budget. The best choice is the one that fits your doctors, drugs, and risk tolerance, and with changes landing January 1, now is the time to compare.
