Medicare Advantage Network Changes in 2026: What Florida Seniors Must Know

If you're on a Medicare Advantage plan in Florida and you didn't carefully review your coverage during last fall's Open Enrollment, there's a real chance something important changed — and you may not know it yet.

2026 brought more Medicare Advantage plan exits, network reductions, and benefit changes than we've seen in several years. Here's what happened, why it happened, and what you can do about it right now.

Several major Medicare Advantage carriers reduced their footprints in Florida for 2026. Some plans that were available in your county in 2025 are simply gone. Others narrowed their service areas, dropping certain counties or ZIP codes.

This isn't unique to Florida — it's a national trend driven by:

• CMS rate adjustments that reduced payments to Medicare Advantage plans
• Higher-than-expected medical costs following the COVID years
• Increased utilization as seniors who deferred care during the pandemic caught up on procedures
• Regulatory scrutiny of prior authorization practices and marketing tactics

The result: fewer choices in some Florida counties, and plans that stayed in the market often made benefit cuts to stay profitable.

Even plans that didn't exit the market often narrowed their provider networks. Hospitals, specialist groups, and primary care practices that were in-network in 2025 may have been dropped for 2026.

This is particularly significant in Northeast Florida, where several major health systems renegotiated (or failed to renegotiate) contracts with Medicare Advantage carriers.

Many plans reduced or eliminated extra benefits that had become standard in recent years:

• OTC (over-the-counter) allowances were reduced or eliminated on some plans
• Dental benefits were scaled back on several plans
• Fitness benefits (gym memberships) were cut on some plans
• Transportation benefits were reduced

If you chose your plan partly because of these extras, verify they're still included — and at what level.

Every Medicare Advantage plan is required to send you an Annual Notice of Change by September 30 each year. This document lists every change to your plan for the coming year — premiums, copays, network changes, and benefit changes.

If you received this document last fall and set it aside, now is the time to read it.

Call the member services number on your insurance card and ask:

• "Is [your doctor's name] still in-network for my plan?"
• "Is [your hospital] still in-network?"
• "Has my out-of-pocket maximum changed from last year?"
• "Are my medications still on the formulary at the same tier?"

Most plans have an online provider directory where you can search by doctor name or hospital. These directories are updated more frequently than printed materials — but they're not always 100% current. When in doubt, call.

The Medicare Advantage Open Enrollment Period runs January 1 – March 31 each year. During this window, you can:

• Switch from one Medicare Advantage plan to another
• Switch from Medicare Advantage back to Original Medicare (and add a Medigap plan and Part D)

You can only make one change during this period. If you're still within this window, act now.

Certain life events trigger a Special Enrollment Period (SEP) that allows you to make plan changes outside the normal enrollment windows. Relevant SEPs include:

• Moving to a new address outside your plan's service area
• Losing coverage due to a plan exit from your county
• Qualifying for Extra Help (Low Income Subsidy)
• Entering or leaving a skilled nursing facility

If your plan exited your county for 2026, you should have received a notice and been granted an SEP to choose a new plan.

If you're outside the Open Enrollment Period and don't qualify for an SEP, your next opportunity to change plans is the Annual Enrollment Period: October 15 – December 7, 2026 (for coverage starting January 1, 2027).

In the meantime, you can still see out-of-network providers — but you'll pay significantly more, and HMO plans may not cover out-of-network care at all except in emergencies.

The network issue hits HMO plan members hardest.

HMO (Health Maintenance Organization): You must use in-network providers except in emergencies. If your doctor leaves the network, you either find a new in-network doctor or pay 100% out of pocket.

PPO (Preferred Provider Organization): You can see out-of-network providers, but you pay more. If your doctor leaves the network, you can still see them — just at a higher cost.

If you're on an HMO and your primary care doctor or a key specialist is no longer in-network, this is a significant problem that warrants immediate action.

One of the most common conversations I have with clients after a network disruption is about switching to Original Medicare with a Medigap supplement.

Why Medigap avoids the network problem entirely:

With Original Medicare + Medigap, you can see any doctor or hospital in the country that accepts Medicare — no networks, no referrals, no prior authorizations. If your doctor accepts Medicare, they accept you.

The trade-off: Medigap premiums are higher than most Medicare Advantage premiums, and you'll need a separate Part D plan for drug coverage.

The catch on switching: Moving from Medicare Advantage to Medigap typically requires medical underwriting — you'll need to answer health questions and could be denied or charged more based on pre-existing conditions. The exception is if you're within your first year of Medicare Advantage enrollment (you have a guaranteed right to return to Original Medicare).

If you're considering this switch, the time to do it is when you're healthy. I can walk you through whether it makes sense for your situation.

In the counties I serve — Flagler, Volusia, St. Johns, Duval, and Putnam — the 2026 Medicare Advantage landscape shifted meaningfully:

• Several plans that had strong networks in 2024–2025 made significant network changes
• The Mayo Clinic network remains a critical consideration for St. Johns and Duval County residents — not all plans include Mayo
• UF Health and Baptist Health network participation varies by plan
• Rural areas (particularly Putnam County) have fewer plan options and narrower networks

If you're in Northeast Florida and want to know specifically which plans include your doctors and hospitals, I can run that analysis for you at no charge.
