Epic has spent the past several years pulling in many of the country’s largest health systems, a large share of them leaving Oracle Health. Four more large systems, Adventist Health, Avera Health, ChristianaCare and Kaleida Health, went live on Epic in 2026 alone.
But a group of large U.S. health systems remains on other vendors, and the biggest names among them are investor-owned operators: HCA Healthcare, Tenet Healthcare, Community Health Systems, Universal Health Services and Lifepoint Health. Most of the nonprofit and public systems still off Epic run Oracle Health, and several have recently deepened that relationship rather than leave it.
Here are 19 of the largest health systems that are not on Epic and have not announced a systemwide move to it, listed by revenue:
1. HCA Healthcare (Nashville, Tenn.): Meditech. The roughly 190-hospital for-profit system is midway through a multiyear move to Meditech’s cloud-based Expanse platform. Another 34 of its hospitals went live in September, after 43 in January.
2. Ascension (St. Louis): Epic, Oracle Health, Meditech and Athenahealth. Ascension runs Epic in some markets alongside three other vendors and has not announced a plan to consolidate on a single EHR.
3. Tenet Healthcare (Dallas): Oracle Health. The for-profit operator runs Oracle Health across its hospitals.
4. Universal Health Services (King of Prussia, Pa.): Oracle Health. UHS explained to Becker’s in 2024 why it chose to stay with Oracle rather than switch EHRs.
5. Community Health Systems (Franklin, Tenn.): Oracle Health, Athenahealth and MedHost. CHS is also working with Oracle Health to deploy its enterprise resource planning system enterprisewide.
6. Banner Health (Phoenix): Oracle Health. Banner is the largest nonprofit system on this list that runs a single non-Epic vendor.
7. Lifepoint Health (Brentwood, Tenn.): Multiple EHRs. Lifepoint’s CIO, Al Smith, told Becker’s the company worked with nearly every EHR on the market.
8. Prime Healthcare (Ontario, Calif.): Multiple non-Epic EHRs. Most of Prime’s hospitals run on non-Epic systems. Epic comes into the system only with nine Illinois hospitals it agreed to acquire from Ascension for a base price of $375.8 million.
9. Encompass Health (Birmingham, Ala.): Oracle Health. The inpatient rehabilitation operator runs Oracle Health across more than 150 hospitals.
10. BayCare Health System (Clearwater, Fla.): Oracle Health. BayCare worked with Oracle Health on new capabilities for the vendor’s health system operations suite in 2025.
11. Los Angeles County Department of Health Services: Oracle Health. The department told the county board of supervisors June 10 that it would begin sole-source negotiations with Epic to replace Oracle Health. No contract has been signed.
12. Huntsville (Ala.) Hospital Health System: Oracle Health. The system said in March 2025 that it would standardize on the Oracle Health Foundation EHR across all of its facilities.
13. Billings (Mont.) Clinic-Logan Health: Oracle Health. The combined 30-hospital system is in a roughly three-year rollout of Oracle Health that began with its critical access hospitals in early 2025.
14. Baystate Health (Springfield, Mass.): Oracle Health. Baystate expanded its collaboration with Oracle Health in June.
15. Cook County Health (Chicago): Oracle Health. The public system has posted a request for proposals for a new EHR.
17. MU Health Care (Columbia, Mo.): Oracle Health. The academic system uses Oracle Health.
18. Stony Brook (N.Y.) Medicine: Oracle Health. Stony Brook’s patient portal still runs on Oracle’s HealtheLife.
19. ScionHealth (Louisville, Ky.): Multiple EHR vendors.
