Central Florida's largest health system — 5 campuses across Orange and Osceola counties. Here's what every Medicare beneficiary needs to know about coverage, networks, and prior authorization.
Five campuses across Central Florida — each with different Medicare Advantage network participation.

AdventHealth is the dominant health system in Central Florida, with campuses across Orange, Osceola, Seminole, and Lake counties. For Medicare beneficiaries in the Orlando metro area, AdventHealth is often the primary hospital system. Understanding which Medicare plans cover AdventHealth — and at what cost — is one of the most important decisions you'll make when choosing a plan.
AdventHealth participates in most major Medicare Advantage networks serving Orange and Osceola counties. Humana, Florida Blue, UnitedHealthcare, Aetna, WellCare, Devoted Health, and Cigna have historically included AdventHealth in their networks. However, network participation changes annually — and some plans may include the flagship Orlando campus but not all affiliated campuses. Always verify your specific plan and campus before enrolling.
AdventHealth Orlando holds a Level II Trauma Center designation, making it one of the primary trauma destinations in Central Florida. Medicare law requires all Medicare Advantage plans to cover emergency care at any hospital, including AdventHealth, regardless of network status. However, post-stabilization inpatient care may be subject to network rules and prior authorization requirements.
AdventHealth Orlando's Heart & Vascular Institute is one of the most comprehensive cardiac programs in Florida. For Medicare beneficiaries with heart disease — the leading cause of death among seniors — having access to AdventHealth's cardiac specialists without prior authorization is a significant advantage of Medigap over Medicare Advantage.
Because AdventHealth accepts Original Medicare, any Medigap plan gives you full access to all AdventHealth campuses — with no prior authorization, no referrals, and no network restrictions. Medigap Plan G is the most popular choice for Central Florida seniors: after the Part B deductible, you pay nothing for Medicare-covered services at any AdventHealth facility.
Medicare Advantage plans often require prior authorization for specialist visits, elective procedures, and certain diagnostic tests at AdventHealth. This is one of the most significant differences between Medicare Advantage and Original Medicare + Medigap. With Medigap, you can see any AdventHealth specialist without prior authorization. With Medicare Advantage, your plan may require approval before certain services.

|---|---|---|
| Access to AdventHealth | Depends on plan network | All campuses, no restrictions |
| Prior Authorization | Often required for specialists | Not required |
| Monthly Premium | Some plans with $0 may be available | Typically $100–$250/mo |
| Out-of-Pocket Max | Up to $8,850/year (in-network) | Near-zero with Plan G |
| Referrals Required | HMO: yes; PPO: usually no | Never |
| Cardiac Specialist Access | Prior auth may be required | No restrictions |
| Nationwide Coverage | Network-based (PPO more flexible) | Any Medicare-accepting provider |
