The December 31, 2026 Contract Deadline Explained
AdventHealth and UnitedHealthcare are locked in high-stakes contract negotiations across Florida, with their current provider network agreement scheduled to expire on December 31, 2026. Both organizations have published public negotiation updates stating that if a renewed agreement is not reached before the deadline, AdventHealth hospitals, outpatient facilities, urgent care clinics, and employed physician groups in Florida would become out-of-network for UnitedHealthcare plans effective January 1, 2027.
Through December 31, 2026, nothing changes for current patients: all AdventHealth hospitals and physicians remain in-network under existing 2026 contract terms. However, because the December 31 contract expiration date lands immediately after fall enrollment windows close, patients in Polk County, Greater Orlando, Tampa Bay, and Volusia/Flagler must verify their 2027 provider directories carefully before locking in a 2027 plan.

Emergency Care vs. Non-Emergency Services in 2027
Whether you carry a Medicare Advantage plan, an Individual Marketplace policy, or an employer group plan, federal law separates true medical emergencies from scheduled care:
| Service Category | If Contract Expires Jan 1, 2027 | How Patient Billing & Coverage Work |
|---|---|---|
| Hospital Emergency Rooms (ER) | Protected by Federal Law | Covered at in-network cost-sharing under the federal No Surprises Act and Medicare emergency rules at all AdventHealth ERs, regardless of network contract status. |
| Scheduled Surgeries & Inpatient Admissions | Out-of-Network for UHC Plans | Non-emergency hospital admissions, imaging, and outpatient procedures require an active network contract (or approved continuity-of-care transition) to avoid out-of-network denials or higher cost-sharing. |
| AdventHealth Medical Group, Primary Care+ & Bond Clinic | Out-of-Network for UHC Plans | Routine primary care visits, specialist follow-ups, and Centra Care urgent care visits follow the plan's 2027 directory participation rules. |
| Original Medicare + Medigap (Plan G / Plan N) | Unaffected by Carrier Dispute | Original Medicare beneficiaries with any Medigap supplement can visit any hospital or doctor accepting Medicare assignment without network restrictions. |
4 Action Steps for Patients Before 2027 Enrollment Deadlines
- Check Both Hospital and Physician NPIs by Exact 2027 Plan ID: Hospital systems and employed medical groups (such as AdventHealth Medical Group, Primary Care+, and Bond Clinic in Winter Haven) bill under distinct tax IDs. Always verify your exact 2027 plan ID in the official provider directory or on Medicare.gov Plan Finder.
- Compare Alternative 2027 Carriers That Contract With AdventHealth: In Polk County, Central Florida, and Tampa Bay, multiple 2027 Medicare Advantage and ACA Marketplace carriers maintain active network agreements with AdventHealth hospitals and physicians. Reviewing side-by-side options lets you see which plans cover both your AdventHealth specialists and your prescription formulary.
- Review Original Medicare + Medigap Options: For Medicare beneficiaries who want to avoid annual hospital-carrier contract disputes altogether, Original Medicare paired with a Medicare Supplement (Medigap Plan G or Plan N) and a standalone Part D drug plan covers any provider in the United States that accepts Medicare assignment.
- Request Continuity of Care If You Are in Active Treatment: Patients undergoing active treatment for a serious or complex condition—such as oncology/chemotherapy, radiation, pregnancy, or post-surgical follow-up—may qualify for temporary Continuity of Care protections (up to 90 days of transitional in-network coverage under federal Continuity of Care rules and Florida Statute § 627.64194). Call the member services number on the back of your insurance card to request a Continuity of Care form if a contract expires.
Key 2027 Enrollment Windows: Medicare's Annual Enrollment Period (AEP) runs from October 15 through December 7, 2026 for a January 1, 2027 effective date, followed by the Medicare Advantage Open Enrollment Period from January 1 through March 31, 2027. Florida's ACA Marketplace Open Enrollment runs from November 1, 2026 through January 15, 2027 (select your plan by December 15, 2026 for coverage starting January 1, 2027).

The current provider network agreement between AdventHealth and UnitedHealthcare in Florida is scheduled to expire on December 31, 2026. Care and in-network coverage continue unchanged through December 31, 2026, while contract negotiations remain underway for the 2027 plan year.
Which health insurance plans are affected if AdventHealth and UnitedHealthcare do not reach a 2027 agreement?
If a renewed contract is not reached before January 1, 2027, the network change would affect UnitedHealthcare Medicare Advantage plans (including AARP-branded Medicare Advantage plans), Individual and Family ACA Marketplace plans, employer-sponsored commercial group plans, and Medicaid plans across Florida.
Are emergency room visits at AdventHealth hospitals still covered if a contract expires?
Yes. Under the federal No Surprises Act and Medicare emergency coverage rules, emergency room evaluation and stabilization at any AdventHealth hospital emergency department, including AdventHealth Heart of Florida, AdventHealth Lake Wales, AdventHealth Orlando, and AdventHealth Tampa, must be processed at in-network cost-sharing levels regardless of network contract status.
