Thousands of Orange County seniors are about to be affected by the UnitedHealthcare and Providence Mission Termination in 2026, which officially ends their Medicare Advantage contract after December 31, 2025. This means that starting in 2026, Mission Hospital and Providence facilities will no longer be in-network for UnitedHealthcare Medicare Advantage HMO members—a major shift for many Mission Viejo and Laguna Beach residents who rely on Mission Hospital for their care.
Skyline Benefit is an independent Medicare broker helping seniors across California navigate major plan changes like this. If you’re a current UnitedHealthcare member, here’s what the contract termination means for you—and what you can do to protect your coverage before it’s too late.
Why Is UnitedHealthcare Ending Its Contract with Providence Mission?
Providence Health, which owns Mission Hospital, and UnitedHealthcare could not reach an agreement to renew their Medicare Advantage HMO contract for 2026. As a result, the UnitedHealthcare and Providence Mission Termination 2026 takes effect on December 31, 2025, ending a long-standing relationship between the two organizations.
This decision affects all UHC Medicare Advantage HMO members in the Mission Hospital and Providence Affiliated Physicians. Beginning January 1, 2026, these providers will be out-of-network, potentially leading to higher out-of-pocket costs and limited access to your preferred doctors and facilities.
What This Means for Mission Viejo Medicare Advantage Members
Here’s what affected members should know:
- Mission Hospital and Providence facilities will no longer be in UnitedHealthcare’s Medicare Advantage network after 12/31/25.
- UHC may automatically reassign members to non-Providence primary care doctors and facilities.
- Continuity-of-care rules allow approved ongoing treatments to continue temporarily.
- UHC Medicare Supplement (Medigap) and commercial plans are not affected—only Medicare Advantage HMO plans.

I Already Re-Enrolled for 2026—What Now?
Even if you’ve already re-enrolled, you’re not stuck. You can change your plan during Medicare’s Annual Enrollment Period (AEP), October 15 – December 7, 2025.
If you miss that deadline, you’ll have another opportunity during the Medicare Advantage Open Enrollment (OEP), January 1 – March 31, 2026.
To keep your Mission Hospital providers, you’ll need to switch to a 2026 Medicare Advantage plan that still contracts with Providence.
