Hospitals using Epic: how many there are, and how to build a list of hospitals by EHR

Searches for "hospitals using Epic" usually come from two kinds of people: Health IT sellers who need a target list, and people curious about Epic's reach. This guide answers the share question with sourced numbers, explains why those numbers disagree, and shows how to build the list yourself. It does not list hospitals.

How many hospitals use Epic in 2026

No public source publishes an exact count of US hospitals on Epic. What exists are shares from surveys and research firms, each counting a different set of hospitals.

The best public figure comes from the federal government. ONC's final data brief on hospital EHR adoption, based on the 2024 AHA IT Supplement survey, found that 50.8% of non-federal acute care hospitals used Epic as their certified EHR developer.¹

For scale, the AHA counts about 6,100 US hospitals in total.² Epic itself says more than 325 million patients have a current record in Epic.³

What percentage of US hospitals use Epic, Oracle Health and MEDITECH

Three developers cover most US hospitals. In ONC's 2024 figures, the top three held more than 80% of non-federal acute care hospitals.¹

The market has shifted a long way. MEDITECH led in 2010 with 23.3% of hospitals.¹ And hospitals have consolidated vendors: over 90% used the same EHR developer for inpatient and outpatient care in 2024, up from 62% in 2010.¹

Why hospital EHR market share numbers differ from source to source

You will see Epic's share quoted anywhere from about 40% to over 55%. The numbers are not wrong. They count different things.

Bed share runs higher than hospital share because Epic is strongest in large hospitals. Survey shares differ from census-style counts because not every hospital answers the survey. Before you size a territory, pick the denominator that matches your market: hospitals or beds, acute care only or every hospital type.⁴

Hospitals using Epic by bed size: where Epic leads and where it does not

Epic is not equally strong everywhere. KLAS's 2025 figures, as reported by Becker's, show Epic leading large health systems, small systems of two to ten hospitals, standalone hospitals with more than 200 beds, academic medical centers and children's hospitals.⁵

The small standalone market looks different. MEDITECH led standalone hospitals with 26 to 200 beds, and Oracle Health led standalone hospitals with 25 beds or fewer.⁵

For a seller, that changes the pitch. Integration with Epic matters most for large hospitals and systems. For small community hospitals, check MEDITECH, Oracle Health and TruBridge support before you build the campaign.

Hospitals using Cerner: what changed when Oracle bought Cerner

Cerner is now Oracle Health. Oracle completed its acquisition of Cerner in June 2022.⁶ People still search for "hospitals using Cerner", so most reports list the product as Oracle Health or Oracle Cerner.

Oracle Health was second in ONC's 2024 figures, at 20.1% of non-federal acute care hospitals.¹ KLAS, as reported by Becker's, counted a net loss of 56 Oracle Health hospitals in 2025 and a net gain of 77 for Epic.⁴

What EHR small and critical access hospitals use

Small hospitals have caught up on adoption. ONC reports that 99.3% of hospitals with fewer than 100 beds, 99.5% of rural hospitals and 99.5% of critical access hospitals had a certified EHR in 2024.¹

Which EHR they run is more varied than in large hospitals. Besides MEDITECH, Oracle Health and TruBridge, many small hospitals run Epic through a host program, where a larger health system extends its Epic instance to smaller hospitals and practices, such as Epic's Community Connect.⁷

How to find out what EHR a hospital uses with free public data

Two free federal files answer this question, and they join on the hospital's CMS Certification Number (CCN).

1. ONC's hospital certified health IT dataset. ONC publishes the certified health IT that hospitals reported for CMS's Promoting Interoperability program, with each hospital's CCN, EHR developer and product.⁸
2. The CMS Provider of Services file. CMS publishes every certified hospital's CCN, state, bed count and type of control, updated quarterly.⁹

Join the two on the CCN and you have each hospital's EHR, state and bed count in one table. Pad CCNs to six digits first, since some downloads drop the leading zero.

How to build a list of hospitals using Epic by state and bed size

With the joined table, building a target list takes a few filters.

1. 1

   Filter by EHR developer

   Keep the hospitals that report Epic, or whichever EHRs your product supports.

2. 2

   Filter by state and bed count

   Use the Provider of Services file's state and bed fields to match your territory and ideal hospital size.

3. 3

   Add the parent system

   Look up which health system each hospital belongs to, since the system usually owns the EHR decision. See how to find out who owns a hospital.

4. 4

   Add size and finances

   Pull beds, discharges and revenue from the Medicare cost report if you qualify on them.

5. 5

   Find the people

   Add the CIO, CMIO, CNIO and applications leaders at each hospital and its system.

The public files tell you what a hospital reported for a federal program in a past year. Check recent news for EHR changes before you act on the list.

Why the health system, not the hospital, usually picks the EHR

About 70% of community hospitals belong to a health system, according to the AHA.² Systems tend to standardize on one EHR across every hospital and clinic they own, which is why over 90% of hospitals now run the same developer inpatient and outpatient.¹

So the EHR decision, and many decisions about products that connect to it, sit with the system. The hospital IT manager can be a champion, but the system CIO, CMIO and the IT steering committee decide. See how hospitals buy IT software for the full path.

How to find the CIO and IT leaders at hospitals using Epic

For a Health IT sale, these are the roles to find at each hospital and at its parent system:

• CIO or VP of IT. Owns the IT budget and the EHR relationship.
• CMIO and CNIO. The physician and nursing informatics leaders who judge clinical fit.
• VP or director of applications. Runs the EHR team and the integrations.
• EHR application analysts. Build and maintain the workflows your product would touch.
• CISO. Runs the security review every new system has to pass.

Dmand AI maps 1.6K+ health systems and IDNs down to 6.2K+ hospitals and 997K+ sites of care, with 11M+ healthcare executives attached to the site they run, so you can see the system CIO and the hospital IT director in the same tree. Site profiles include technology installs, and you can filter hospitals by EHR, state and size.

Why EHR switches are buying signals for Health IT sellers

An EHR change is one of the biggest projects a hospital runs, and it opens doors for other vendors. When a system moves to a new EHR, it needs integration work, data migration, go-live support staff, training, analytics and often new point solutions that fit the new platform.

Watch for systems announcing a new EHR, small hospitals joining a larger system's host program, and acquisitions where the new owner moves hospitals onto its own EHR. KLAS, as reported by Becker's, found that only two large systems of ten or more hospitals made an EHR decision in 2025, and both chose Epic, so each large switch is a rare and valuable window.⁴
