Medicare Advantage Network Changes in 2026: What Florida Seniors Need to Do Right Now

Every year on January 1, Medicare Advantage plans can change their provider networks. Doctors, hospitals, and specialists who were in-network last year may not be in-network this year -- and vice versa.

This is one of the most important -- and most overlooked -- aspects of Medicare Advantage. If your doctor leaves your plan's network and you don't notice until you're at the appointment, you could face significantly higher out-of-pocket costs.

Here's what you need to know for 2026.

Medicare Advantage plans negotiate contracts with providers annually. When a contract expires, the provider and the plan must renegotiate. If they can't agree on terms, the provider leaves the network.

This happens more often than most people realize. In 2025, several major Florida health systems had contract disputes with Medicare Advantage carriers -- including temporary network disruptions that affected thousands of seniors.

The bottom line: Never assume your doctors are still in-network just because they were last year.

Step 1: Find your plan's provider directory Every Medicare Advantage plan must maintain an online provider directory. Go to your plan's website and search for your doctors by name or NPI number.

Step 2: Call your doctor's office directly Provider directories are often outdated. The most reliable way to verify network status is to call your doctor's office and ask: "Do you accept [Plan Name] for 2026?"

Step 3: Check your Annual Notice of Change (ANOC) Every fall, your plan sends an Annual Notice of Change listing all changes to benefits, premiums, and networks for the upcoming year. Read it carefully -- especially the network section.

Step 4: Work with an independent broker An independent broker can check network status across multiple plans simultaneously and alert you if your doctors are dropping out of your current plan's network.

Several Florida health systems have had ongoing contract negotiations with Medicare Advantage carriers. Here are the key situations to watch:

AdventHealth: AdventHealth has had periodic contract disputes with certain Medicare Advantage carriers. Always verify AdventHealth network status for your specific plan before the new year.

HCA Florida: HCA operates multiple hospitals across Florida and has had network disputes with several carriers. Check your specific HCA hospital's status.

UF Health: UF Health's network participation varies by campus and by plan. A plan that covers UF Health Shands may not cover UF Health Jacksonville.

Independent specialists: Specialist physicians -- particularly in high-demand specialties like oncology, cardiology, and orthopedics -- are more likely to leave networks than primary care physicians.

Option 1: Appeal for continuity of care If you're mid-treatment (e.g., undergoing chemotherapy, recovering from surgery), you may have the right to continue seeing your out-of-network provider temporarily at in-network rates. Contact your plan immediately.

Option 2: Switch plans during AEP If you discover the network change before December 7, you can switch to a plan that includes your doctor during the Annual Enrollment Period (October 15 - December 7).

Option 3: Use the Medicare Advantage Open Enrollment Period From January 1 - March 31, you can switch from one Medicare Advantage plan to another, or switch to Original Medicare. This is your safety valve if you discover a network problem after January 1.

Option 4: Consider switching to Medigap If network instability is a recurring concern, Medigap (Medicare Supplement) eliminates the network problem entirely. With Medigap, you can see any Medicare-accepting provider in the country -- no network restrictions, no annual network changes to worry about.

This is worth emphasizing: Medigap plans have no provider networks. If your doctor accepts Original Medicare, they accept your Medigap plan. Period.

You never have to worry about your doctor leaving your network. You never have to check a provider directory. You never have to call your doctor's office to verify network status.

The trade-off is a monthly premium (typically $100-$250/month in Florida). But for many seniors -- especially those with established relationships with multiple specialists -- the certainty of Medigap is worth the cost.

Every fall before the Annual Enrollment Period, I review every client's current plan and check:

1. Whether their doctors are still in-network for the coming year
2. Whether their prescriptions are still on the formulary
3. Whether a better plan is available in their ZIP code
4. Whether switching to Medigap makes more sense given their health situation

This review is completely free. If your plan is still the best option, I'll tell you. If a better option exists, I'll show you exactly what it is and what it costs.
