What actually happened to Medicare Advantage
Medicare Advantage plans did not disappear or get cut off under President Biden. What changed were the rules about how much insurance companies can charge for extra services, how much they pay doctors, and what they must cover. The biggest change came in 2024, when the Centers for Medicare & Medicaid Services (CMS) reduced the amount it pays insurers for each person enrolled in a Medicare Advantage plan. This affected plan premiums, benefits, and provider networks — but the program itself continued operating.
If you are already in a Medicare Advantage plan, you kept your coverage. If you were thinking about joining one, the plans available to you may have changed in scope or cost compared to previous years. Understanding what shifted and why helps you decide whether your current plan still fits your needs or whether you should look at other options during the next enrollment period.
Key Takeaways
- Medicare Advantage plans continued to operate; no one lost coverage automatically, but benefits and costs changed for many plans starting in 2024.
- CMS reduced payment rates to insurance companies, which led some insurers to raise premiums, cut extra benefits like dental or vision, or narrow their provider networks.
- Some plans exited certain counties or states entirely, meaning people in those areas had to choose a different plan during open enrollment.
- You can review your plan's changes every year during the Annual Enrollment Period (October 15 to December 7) and switch to a different plan if your current one no longer meets your needs.
How payment changes affected plan offerings
The federal government pays Medicare Advantage insurers a fixed amount per enrollee each month. In recent years, that amount grew. Starting in 2024, CMS changed the formula and reduced those payments in many regions. When insurers receive less money per person, they have three main options: raise what members pay out of pocket, reduce the extra benefits they offer, or limit which doctors and hospitals are in the plan's network.
Some insurers chose all three. Plans that previously offered $0 premiums began charging monthly fees. Dental, vision, and hearing benefits that were once included got scaled back or removed entirely. Networks that included major hospital systems shrank to exclude certain providers. Other insurers stayed in the market but reduced their service area, leaving some counties without any plans from that company.
The changes were not uniform. A plan in Florida might have raised premiums while keeping benefits intact, while the same company's plan in Arizona might have cut benefits but held premiums steady. Your own plan's changes depend on where you live, which insurer runs your plan, and how that insurer decided to respond to lower federal payments.
Which people were most affected
People already enrolled in Medicare Advantage saw the impact most directly. If your plan changed its benefits or network, you received a notice in the mail explaining what was different for the coming year. If your plan exited your county entirely, you were automatically moved to another plan — usually one chosen by CMS based on similar coverage — but you could switch to a different plan during open enrollment if you preferred.
People shopping for a new Medicare Advantage plan for the first time found fewer options in some areas. Counties that previously had 20 or more plans to choose from sometimes dropped to 15 or fewer. In rural areas, the reduction was often steeper. This meant less choice, though at least one plan remained available in every county.
People on Original Medicare (not Medicare Advantage) were not directly affected by these changes. Their coverage and costs work differently because Original Medicare is run by the federal government, not by private insurers.
Why the federal government made these changes
CMS stated that previous payment rates were higher than necessary to cover the actual cost of care for Medicare Advantage members. The agency said it was adjusting payments to be more accurate and to keep the Medicare trust fund sustainable. Insurers and some members argued that the cuts were too steep and would harm access to care and benefits.
This disagreement reflects a broader tension: Medicare Advantage has grown rapidly because plans offer extra benefits like dental and vision that Original Medicare does not cover. Those extras cost money. The question of how much the federal government should pay for them — and whether that payment should come from general Medicare funds or from members' pockets — remains contested between insurers, patient advocates, and policymakers.
How to find out what changed in your plan
Every October, Medicare sends you a notice called the "Annual Notice of Change" (ANOC) if you are in a Medicare Advantage plan. This document lists what is different about your plan for the coming year: new premiums, changes to copays and deductibles, benefits that were added or removed, and changes to the provider network. Read it carefully, even if you think you will stay in the same plan.
You can also call your plan's customer service number (on your insurance card) and ask directly what changed. Ask specifically about: monthly premium, copays for doctor visits and prescriptions, whether your current doctors are still in-network, and whether benefits like dental, vision, or hearing coverage changed. Write down the answers so you have them in writing.
If you want to compare your current plan to other options available in your area, visit Medicare.gov and use the plan comparison tool. You can enter your doctors and medications to see which plans cover them and at what cost. This tool is available year-round, but changes take effect only if you switch during the Annual Enrollment Period (October 15 to December 7).
When you can switch plans or go back to Original Medicare
The Annual Enrollment Period runs from October 15 to December 7 each year. During this window, you can switch from one Medicare Advantage plan to another, or from Medicare Advantage to Original Medicare. Any change you make takes effect on January 1 of the following year.
If your plan exited your county, you get a special enrollment period — usually 60 days — to switch without waiting for October. CMS notifies you by mail if this applies to you. If you miss that window, you can still switch during the regular Annual Enrollment Period.
If you move to a new state or county, you can switch plans within 60 days of your move, even outside the Annual Enrollment Period. You will need to show proof of your new address.
Questions to ask your doctor or plan
Before the Annual Enrollment Period ends, contact your primary care doctor's office and ask: "Will my insurance still cover me at this practice next year?" Network changes sometimes happen without patients realizing it. If your doctor is no longer in-network, ask whether they accept your plan's out-of-network rates or whether you need to find a new doctor.
Ask your plan's customer service: "What is my out-of-pocket maximum for next year?" and "If I need a specialist, do I still need a referral from my primary care doctor?" These details shift year to year and affect how much you will actually pay when you use care.
If you take regular medications, ask the plan: "Are all my current medications on the formulary, and at what tier?" Formularies change, and a drug you paid $10 for this year might move to a higher tier next year, raising your copay.
Frequently Asked Questions
Did I lose my Medicare Advantage coverage?
No. If you were enrolled in a plan, you remained enrolled. If your plan exited your county, you were automatically moved to another plan, but you kept coverage without a gap. You can switch to a different plan during the Annual Enrollment Period if you want to.
Will my premiums go up because of Biden's changes?
Some plans raised premiums; others did not. It depends on your specific plan and where you live. Check your Annual Notice of Change or call your plan to see what your premium will be next year. If it increased significantly, compare other plans available in your area during open enrollment.
Can I switch back to Original Medicare if my Medicare Advantage plan got worse?
Yes. During the Annual Enrollment Period (October 15 to December 7), you can switch from Medicare Advantage to Original Medicare. You will also need to enroll in a Medigap or Part D plan if you want prescription drug coverage and supplemental insurance. The switch takes effect January 1.
What if my doctor is no longer in my plan's network?
Call your plan and ask whether your doctor will be in-network next year. If not, ask whether they accept your plan's out-of-network rates. If the cost is too high, you can switch to a different Medicare Advantage plan during open enrollment, or switch to Original Medicare and find a new doctor who accepts it.
How do I know which plan is best for me now?
Use the plan comparison tool at Medicare.gov. Enter your doctors, medications, and preferred hospitals to see which plans cover them and at what cost. Compare the total you would pay out of pocket across all plans, not just the premium. Call the plans' customer service lines with questions before you decide.
