Sumter County is unlike any other county in Florida. Home to a large portion of The Villages, the master-planned retirement community that straddles Sumter, Marion, and Lake counties, it consistently ranks as one of the fastest-growing and highest-income counties in the entire United States by Census metrics. Its population skews heavily toward retirement age — most residents are 65 and older — which means Medicare is the dominant health insurance product here, and the differences between Medicare Advantage, Original Medicare, and Medigap matter enormously for the county's residents.
The key health system serving Sumter County and The Villages is UF Health The Villages Hospital, a full-service acute care facility that opened in 2014 and has expanded significantly to serve the area's growing population. The Cleveland Clinic and AdventHealth systems also have facilities nearby through the broader Central Florida corridor. For residents of The Villages specifically, understanding which Medicare plans include UF Health and the broader hospital network is the most important factor in plan selection.
Medicare Advantage in Sumter County
Medicare Advantage (Part C) plans are very well represented in Sumter County. The combination of a large, relatively affluent, and Medicare-eligible population makes the market attractive for carriers. Major plans available in the county include:
- Humana — HMO and PPO options; strong presence in The Villages corridor with extensive primary care and specialist networks
- UnitedHealthcare (AARP) — broad network PPO plans; popular among residents who want flexibility for specialist visits
- Aetna — competitive Medicare Advantage options including plans with strong dental and vision benefits
- Florida Blue (BCBS) — Medicare Advantage and supplement products; PPO flexibility attractive to snowbirds
Many Medicare Advantage plans in Sumter County carry $0 monthly premiums, though cost-sharing (copays, deductibles) applies to services used. Plans increasingly include supplemental benefits such as dental, vision, hearing aids, fitness memberships (SilverSneakers), and over-the-counter allowances — benefits that align well with The Villages lifestyle.
Medicare Supplement (Medigap) Plans
A significant portion of Sumter County residents — particularly those who prioritize healthcare flexibility and nationwide access — choose Original Medicare paired with a Medigap supplement rather than Medicare Advantage. Key advantages of the Medigap approach in this market:
- No network restrictions — any provider in the United States who accepts Medicare accepts you
- No prior authorization requirements for specialist visits or procedures
- Predictable out-of-pocket costs — Medigap Plan G, for example, covers virtually everything after the Part B deductible
- Valuable for residents who split time between Florida and another state, traveling frequently, or who want to see Mayo Clinic, Cleveland Clinic, or other major academic medical centers at Original Medicare rates
The tradeoff: Medigap premiums can be substantial, particularly for older enrollees. In Florida, insurers may use medical underwriting outside of your initial enrollment window, which can result in premium loading or denial for those with significant health histories who enroll late.

Lowest Premium, Network Required
$0 or low monthly premium. Includes drug coverage and extra benefits (dental, vision, fitness). Must use in-network providers. Best for residents who stay local.
Flexibility + Lower Cost
Higher premium than HMO but allows out-of-network use at reduced benefit. Good for snowbirds and those who travel for specialty care.
Comprehensive Gap Coverage
Covers all Medicare cost-sharing except the Part B deductible. No networks, no referrals. Best for high healthcare utilizers and frequent travelers.
Prescription Coverage
Required if using Original Medicare + Medigap. Compare formularies based on your specific prescriptions — generics vs. brand names drive the cost difference significantly.
Part D Prescription Drug Coverage
For residents on Original Medicare with a Medigap supplement, a standalone Part D prescription drug plan is required to avoid a late enrollment penalty and to get drug coverage. Part D plans vary significantly in monthly premiums, formularies, and pharmacy networks. The most important step: look up your specific medications in the plan's formulary before choosing. A plan with a $15/month premium may cost you more than a $45/month plan if your key medications are on a higher tier or not covered. Several pharmacies within The Villages and nearby Leesburg and Wildwood are included in preferred pharmacy networks for most major Part D plans.
Annual Enrollment Period — Key Dates
The Annual Enrollment Period (AEP) runs October 15 through December 7 each year. This is when Sumter County residents can switch Medicare Advantage plans, change from Medicare Advantage to Original Medicare (or vice versa), or change Part D plans. Changes take effect January 1. Given the number of plan options available in Sumter County and the frequency with which benefits and premiums change year to year, reviewing your plan annually during AEP is one of the highest-value hours you can spend on your healthcare finances.
The Medicare Advantage Open Enrollment Period (January 1 – March 31) allows one additional plan change for those already enrolled in a Medicare Advantage plan.
ACA Marketplace Plans in Sumter County
While Medicare dominates the Sumter County insurance landscape, there is a smaller population of working-age residents — staff of The Villages communities, healthcare workers, retail and service employees — who need ACA marketplace coverage. Florida Blue (BCBS Florida) and Ambetter from Sunshine Health are the primary carriers serving the ACA market in Sumter County. Income-based Premium Tax Credits are available for those earning between 100% and 400% of the Federal Poverty Level (and higher under current law).
