What Changed in Medicare This Year (And What It Actually Means for Your Parent)

Medicare just published its rule changes for 2026 and 2027. It's 500+ pages of policy language, which is exactly as fun as it sounds. But some of this stuff actually matters if your parent is on Medicare or about to be.

The truth is, most of these changes are technical adjustments that won't change your day-to-day. But a few will affect what plans are available, how much they cost, and what's covered. Here's what to pay attention to.

The Big One: Star Ratings Are Changing

Medicare uses a star rating system (1 to 5 stars) to measure how well Medicare Advantage and Part D prescription drug plans perform. Plans with higher ratings can get bonus payments and are allowed to offer extra benefits.

For 2027, Medicare is changing how those stars are calculated. They're adjusting some of the quality measures and how they weight certain performance factors. The goal is to make the ratings more accurately reflect plan quality and member experience.

Why this matters: Your parent's current plan could move up or down in the ratings, which might affect what extra benefits it offers next year. A plan that's 4 stars today might not be in 2027. This doesn't mean coverage disappears, but it could mean fewer perks like dental or vision coverage, or gym memberships.

The takeaway: Don't assume your parent's plan will stay exactly the same. When open enrollment comes around this fall, actually look at the plan again — don't just auto-renew.

Prior Authorization Rules Are Getting Tighter

If your parent has a Medicare Advantage plan, you've probably bumped into prior authorization — where the insurance company has to approve certain services before they happen. It's one of the more frustrating parts of these plans.

The new rules require Medicare Advantage plans to make prior authorization decisions faster in some cases, and they're adding more oversight to make sure plans aren't denying necessary care. Medicare is also limiting when plans can use prior authorization for certain services.

This is supposed to be good news. The reality is, we'll see. Prior authorization has been a major complaint with Medicare Advantage for years. Whether these changes actually speed things up or reduce denials is something we'll only know by living through it.

Prescription Drug Coverage Adjustments

There are technical changes to how Medicare Part D plans calculate their bids and how they have to structure their drug formularies (the lists of which medications they cover and in what tier).

Here's what that means in practice: The medications your parent takes might move to a different tier next year, which could change the copay. Or a drug that was covered might require a different approval process.

The concrete step: If your parent takes regular medications, write them down now. When you're comparing plans during open enrollment, you can plug that list into Medicare's plan finder tool and see exactly what each plan charges for those specific drugs. Don't pick a plan based on the premium alone — check what you'll actually pay for the medications that matter.

Network Adequacy Standards Are Stricter

Medicare Advantage plans have to meet certain network standards — meaning they need to have enough doctors, specialists, and hospitals available in the area they serve.

The 2026-2027 rules tighten some of those requirements, particularly around behavioral health providers and specialists. Plans have to demonstrate better access to mental health care and certain specialty services.

Practically speaking, this might mean your parent's plan adds more in-network providers. Or, if a plan can't meet the new standards, it might not be available in your parent's county anymore.

What You Actually Need to Do

Nothing right now. These changes are already in effect for 2026 or will be for 2027.

But here's what this means for the next few months:

Before open enrollment this fall, take stock of:

• What plan your parent currently has and what its star rating is
• What medications they're taking regularly
• Whether they've had issues with prior authorization or finding in-network doctors

During open enrollment (October 15 - December 7), don't just renew automatically. Actually compare. Use Medicare's plan finder tool. It's clunky but it works.

Look, I know this is one more thing on the list. But fifteen minutes comparing plans in October can save you hours of phone calls and hundreds of dollars next year. Medicare changes every year — not dramatically, but enough that the plan that worked great in 2025 might not be the best choice for 2027.

The rules changed. Your parent's coverage might too. Better to look now than be surprised later.
