**Short answer**

Most US hospitals are owned by nonprofit organizations, and most belong to a health system. Of 5,121 community hospitals, 58% are nonprofit, 24% investor-owned and 18% government-run. To find who owns a specific hospital, look up its CCN in CMS enrollment data, then check the CMS Hospital All Owners file and the hospital's Medicare cost report.

For a sales team, "who owns this hospital?" is really "who decides here?" The answer changes who signs, which contract applies and which other hospitals come with the deal. This guide shows the national picture, the four different answers the question can have, and a step-by-step lookup with free CMS data.

## Who owns a hospital in the US: most are nonprofit, about a quarter are investor-owned

The AHA counts about 6,100 hospitals in the US.[1] Of the 5,121 community hospitals, 2,984 are nonprofit, 1,224 are investor-owned and 913 are run by state and local governments.[2] Another 210 are federal hospitals, such as those run by the VA.[1]

Most of them sit inside a system. The AHA counts 397 health systems, and 68% of hospitals and 77% of beds belong to one.[3] Six systems run 100 or more hospitals.

| Ownership | Community hospitals | Share |
| --- | --- | --- |
| Nonprofit | 2,984 | 58% |
| Investor-owned (for-profit) | 1,224 | 24% |
| State and local government | 913 | 18% |
| **Total** | **5,121** | **100%** |

## Hospital owner, operator, health system and IDN are four different answers

"Who owns it?" can mean four things, and they are not always the same organization.

1. **The legal entity.** The corporation that holds the Medicare enrollment and the license. It signs contracts in its own name.
2. **The owner.** Anyone with 5% or more direct or indirect ownership, as reported to Medicare. For a nonprofit, that is usually a parent nonprofit corporation.
3. **The operator.** An organization with operational or managerial control, such as a management company running a hospital it does not own.
4. **The health system or IDN.** The organization the hospital belongs to. The AHA counts a hospital as a system member when it is owned, leased, sponsored or contract-managed by a central organization.[1]

[IDN](https://dmand.ai/glossary/integrated-delivery-network-idn), or integrated delivery network, is industry usage for a system that also owns physician groups, outpatient sites, post-acute care and sometimes a health plan. No federal source defines it.

## How to find who owns a hospital with the CMS Hospital All Owners file

CMS publishes two free files that answer most ownership questions. Both come from PECOS, Medicare's enrollment system, and are self-reported by hospitals.[4]

1. **Find the hospital in Hospital Enrollments** Search by name and state to get its CCN, NPI, legal name and enrollment ID.
2. **Pull its rows from Hospital All Owners** Filter by the enrollment ID. Each row is one owner, partner, managing organization, officer or director.
3. **Read the role on each row** The role tells you whether the party owns, manages or governs the hospital (see the next section).
4. **Follow the indirect owners up** Group by the owner's ID to see every hospital the same parent owns.
5. **Check the change of ownership file** The Hospital Change of Ownership file lists buyers, sellers and dates for changes since January 1, 2016.[5]

The owners file is refreshed monthly and holds only current enrollments, so it shows today's owners, not history.[4] Our count of the July 31, 2026 file found 146,859 rows across 9,161 hospital enrollments.

## What 5% direct ownership, indirect ownership and managing control mean in PECOS

Each row in the owners file carries a role code. These are the ones that matter for a seller.[4]

| Role | What it means | What it tells you |
| --- | --- | --- |
| 5% or greater direct ownership | Holds equity in the hospital itself | Who owns the legal entity |
| 5% or greater indirect ownership | Owns part of a company that owns the hospital | The parent and the chain above it |
| Operational or managerial control | Runs the hospital, whether or not it owns it | The operator, often a system or management company |
| Corporate officer | A named officer of the corporation, with a title | The CEO, CFO and others who can sign |
| Corporate director | A named member of the board | Who governs, and who approves large decisions |
| Managing employee (W-2 or contracted) | Someone who runs day-to-day operations | The administrator or operating leader |

The officer and director rows are the part most people miss. In the July 31, 2026 file, corporate directors (61,288 rows) and corporate officers (33,099 rows) far outnumber 5% owners, and the titles include CEO, CFO and president. That is a public, named list of the people who can sign for the hospital.

Hospitals must report anyone with a 5% or greater direct, indirect, mortgage or security interest, all partnership interests, an organizational chart and, for corporations, their officers and directors.[6]

## How a hospital's CCN identifies the hospital and its units

The CCN, or CMS Certification Number, is the six-digit Medicare ID for a certified hospital. The first two digits are the state and the last four mark the facility type: 0001 to 0879 are short-term hospitals and 1300 to 1399 are critical access hospitals, for example.[7]

A letter in the third position marks a unit inside the hospital rather than a separate hospital: S for a psychiatric unit, T for a rehab unit, and U, W or Z for swing-bed approvals. The last three digits match the parent hospital.[7]

> **Pad the CCN to six digits**
>
> In some downloads, CCNs that start with zero lose the leading zero (Alabama hospitals start with 01). Pad every CCN to six digits before you join two CMS files.

## How the Medicare cost report shows a hospital's type of control and chain home office

Every Medicare hospital files an annual cost report, and two places on it help with ownership.[8]

- **Worksheet S-2, Part I, line 21** records the type of control in 13 codes, grouped into nonprofit, proprietary and governmental, such as nonprofit church, proprietary corporation or hospital district.
- **Worksheet S-2, Part I, lines 140 to 143** list the chain home office, if the hospital claims home office costs: the chain number, name and address. That names the parent that runs shared services.

See [how to read a Medicare cost report](https://dmand.ai/blog/medicare-cost-report) for the rest of the report.

## How to trace a hospital up to its health system and ultimate parent

The CMS files name direct and indirect owners, but they do not name the ultimate parent at the top of the chain.[4] You build that yourself.

1. Start with the indirect owners and the party with managerial control.
2. Group by the owner's ID to find every hospital they own or run.
3. Check the chain home office on the cost report.
4. Confirm on the parent's own website, which usually lists its hospitals.

Federal researchers note the limits. CRS reports that GAO and MedPAC found Medicare ownership data not detailed, complete or accurate enough for complex corporate structures.[6]

## How to map a hospital down to every site of care

The hospital is rarely the whole account. Under it sit psychiatric and rehab units, outpatient departments, clinics, physician groups, ASCs and post-acute services, often with their own CCNs or NPIs.

Public data gets you part of the way: units show up as letter CCNs, the cost report lists components such as skilled nursing, home health and rural health clinics, and NPIs can be issued to subparts of an organization.[9] Stitching it into one tree, from the system down to each clinic, is slow by hand.

Dmand AI does that join for you. It maps 1.6K+ health systems and IDNs, 6.2K+ hospitals and 997K+ sites of care in one parent-child tree, with 11M+ healthcare executives and 7.4M+ HCPs attached to the site where they work.

**See any hospital's parent system and every site below it**

Search a hospital, step up to its health system and down to every outpatient site and clinic, with the people at each one.

## Why public hospital ownership data misses private equity and other owners

The owners file is self-reported, and it has blind spots.

- **The 5% floor.** Owners below 5% do not have to be reported.
- **Self-reported flags.** The file has a private equity flag, but it depends on what the hospital reports. The Private Equity Stakeholder Project, which tracks private equity hospital deals, says CMS data alone was not enough to find them.[10]
- **Passive investors.** Large index fund managers can appear as indirect owners of hospitals that belong to publicly traded chains, which says nothing about who runs them.
- **Messy shares.** Because hospitals self-report, ownership shares can add up to more than 100%.[4]
- **No history.** The file shows current enrollments only.

## What a hospital change of ownership (CHOW) means for a deal in progress

A change of ownership can reset a deal. The hospital may become a new legal entity, a new owner's standards and contracts may replace the old ones, and the people who championed your product may change roles.

CMS publishes a quarterly file of changes of ownership, acquisitions, mergers and consolidations since 2016, with buyer, seller and effective date.[5] Watch it for the hospitals in your pipeline. A new owner is also a buying signal: new owners review vendors, standardize systems and bring in their own contracts.

## Why knowing who owns a hospital tells you who signs the contract

Ownership decides where the decision sits. A hospital in a large system may follow system-wide standards for IT, supplies and staffing. A hospital run by a management company may take its direction from the operator. An independent hospital decides for itself.

Before you build the buying committee, answer three questions: which legal entity signs, which system sets the standard, and which other hospitals share the same parent. Then find the people. See [how hospitals buy, by purchase type](https://dmand.ai/blog/selling-to-hospitals) for the roles to look for.

## Questions people ask about hospital ownership

### Who owns most hospitals in the US?

Most US community hospitals are nonprofit. Of 5,121 community hospitals in the AHA's 2026 Fast Facts, 2,984 are nonprofit, 1,224 are investor-owned and 913 are run by state and local governments. Another 210 hospitals are federal, such as VA medical centers.

### How do I find out who owns a hospital?

Look up the hospital's CCN in the CMS Hospital Enrollments file, then find its owners in the CMS Hospital All Owners file, which lists 5% or greater direct and indirect owners, partners, managing organizations, officers and directors. Cross-check the type of control on the hospital's Medicare cost report.

### Who owns a nonprofit hospital?

A nonprofit hospital has no shareholders. It is usually controlled by a nonprofit corporation or a nonprofit health system, governed by a board. In CMS ownership data, the parent corporation often appears as an indirect owner or as having operational or managerial control.

### How many hospitals are part of a health system?

The AHA counts 397 health systems, and 68% of US hospitals and 77% of hospital beds belong to one. Among community hospitals, 3,567 of 5,121, or about 70%, are part of a system.

### What is the difference between a health system and an IDN?

A health system is an organization that owns, leases or manages two or more hospitals, in the AHA's definition. IDN, or integrated delivery network, is industry usage for a system that also owns physician groups, outpatient sites, post-acute care and sometimes a health plan. No federal source defines IDN.

### What is a hospital CCN?

A CCN, or CMS Certification Number, is the six-digit number Medicare assigns to a certified hospital. The first two digits are the state and the last four mark the facility type. A letter in the third position marks a unit, such as a psychiatric or rehab unit, or swing-bed approval.

### Does CMS publish hospital ownership data?

Yes. CMS publishes the Hospital Enrollments and Hospital All Owners files on data.cms.gov, refreshed monthly from Medicare enrollment records, and a Hospital Change of Ownership file covering changes since January 1, 2016. The files show current enrollments only and do not name the ultimate parent.

### How can I tell if a hospital is owned by private equity?

The CMS owners file includes a self-reported private equity flag, but it undercounts. Check the owners and indirect owners listed for the hospital, the parent company's own website and news coverage of the acquisition. Researchers who track private equity ownership say CMS data alone is not enough.
