Start with the Centers for Medicare & Medicaid Services (CMS) Provider Characteristics catalog and choose an All Owners dataset for the provider’s specific facility type. Then use PECOS and NPPES to confirm the entity’s identity, and consult IRS filings or SEC EDGAR when the ownership trail involves a nonprofit or public company. These are useful public-record routes, but none is a universal register that independently proves ultimate ownership.
Choose a source based on the provider type and question
“Who owns this provider?” can mean the name CMS reports for a Medicare-enrolled facility, the legal entity operating a practice, or the parent company at the top of a corporate chain. Those are not always the same. Use records to identify the entity first, then follow documented links between it and any reported owners or parents.

|---|---|---|---|
| CMS All Owners | Named owner rows for covered Medicare facility categories | Self-reported and category-specific; does not necessarily establish ultimate ownership | Dataset month or quarter and owner effective date |
| PECOS public enrollment data | Medicare enrollment and associations with organizations | Public subset focused on enrollment, not exhaustive ownership disclosure | File release date |

| IRS Tax Exempt Organization Search and Form 990 Schedule H | Nonprofit status, hospital facilities, and certain related entities or interests | Tax-year reporting and form-specific disclosures | Tax year and filing date |

| CMS Provider Data Catalog and Care Compare data | Provider identity, category, affiliation, and public quality data | Not an all-owner register | Dataset reporting period |
Start with CMS All Owners, if the provider category is covered
CMS’s Provider Characteristics catalog lists ownership, enrollment, and change-of-ownership data products for several Medicare facility categories. Its listed All Owners datasets include hospitals, skilled nursing facilities, hospices, home health agencies, federally qualified health centers, and rural health clinics. Coverage and release timing differ, so select the matching dataset rather than assuming one file covers all provider types.
The Hospital All Owners dataset includes owner name, owner type, address, and effective date. CMS says the data comes from PECOS, is self-reported by the entity, and is updated monthly. The dataset page showed May 2026 as its latest release when reviewed.
#1 Best Overall
The Home Health Agency All Owners dataset covers HHAs currently enrolled in Medicare and has similar owner fields. CMS describes it as PECOS-derived and self-reported, typically updated quarterly; its page showed Q2 2026 as the latest data when reviewed. For skilled nursing facilities, the Skilled Nursing Facility All Owners dataset includes self-reported, PECOS-derived information and expanded ownership, management, and related-party disclosures that CMS added in 2024.
CMS’s owner rows are documented disclosures, not independent verification of who ultimately controls a provider. A reported owner, landlord, manager, and operating entity may have different legal roles. Do not describe one as another unless the records establish that relationship.
How to use an All Owners file
- Search the CMS Provider Characteristics catalog for the facility category and open the relevant dataset page.
- Note the latest release and stated update frequency. Download or view that release, and keep its month or quarter with your findings.
- Match the facility using its name, address, and available identifier—not name alone. Review the owner’s name, type, address, and effective date.
- Record the owner effective date separately from the dataset release date; they answer different questions about timing.
Use PECOS and NPPES to make sure you have the right entity
PECOS is CMS’s Medicare Provider Enrollment, Chain, and Ownership System. CMS’s provider enrollment resources describe using it to enroll, update information, and reassign privileges to an organization. CMS also publishes a public subset of PECOS enrollment data; its enrollment data fact sheet says the files are sourced directly from PECOS.
Use PECOS public data to check whether similar names refer to the same Medicare provider or supplier, or to see associations with a group or organization. Enrollment information is a connective layer, not exhaustive ownership disclosure for every healthcare business.
Rank #3
The NPPES download page provides National Provider Identifier registry files and reference files, including additional names and non-primary practice locations for individual and organization NPIs. CMS recommends Version 2 files for current downloads; the page listed a Version 2 dissemination update on September 14, 2026. CMS also cautions that receiving an NPI does not validate licensure or credentialing. Use NPIs to disambiguate names and connect locations across records, not as proof of ownership or current practice at an address.
For nonprofit hospitals, read the IRS filings in context
The IRS Tax Exempt Organization Search provides tax-exempt status information and filings, including Form 990-series returns. Search by EIN when possible. The IRS notes that its records use official filed names, which may differ from a hospital’s familiar brand.
For a nonprofit hospital organization, inspect the relevant Form 990 and Schedule H. The Schedule H instructions cover reporting hospital facilities, including facility name, address, and state license number, as well as specified management companies, joint ventures, and certain ownership or profit-share interests involving the organization and insiders or physicians. These are disclosures required within the form’s scope, not a universal commercial ownership filing.

For a public-company parent, search SEC EDGAR
If a provider or an entity in its ownership chain is a public reporting company, search the company name or identifier in SEC EDGAR and review its filings. Look for descriptions of subsidiaries, business structure, acquisitions, and material transactions. Record the filing date and the period it covers.
EDGAR can add detail about a reporting company’s corporate relationships, but it is not a directory of all healthcare provider ownership. A private medical group or individual practice may not appear as a reporting company.
Use CMS directory data as an identity cross-check
The CMS Provider Data Catalog makes official data used by Medicare comparison websites available in open formats. Its resources include hospitals, clinicians, nursing homes, and home health agencies. Use these records to check a provider’s identity, location, or category—not as a replacement for owner disclosures.
CMS’s Physician Compare administrative fact sheet says clinician and group information came primarily from PECOS and describes group practice affiliations and legal business names. That information can help connect an individual clinician to a group, but affiliation alone does not establish that a parent company owns the group.
Quick Recap
Trace and describe the ownership chain carefully
- Identify the provider. Record the exact legal name, any DBA or consumer-facing name, street address, state, provider type, and NPI or CMS Certification Number (CCN), if available.
- Check the relevant CMS owner dataset. Capture the owner name and type, address, effective date, and release month or quarter.
- Match enrollment and identity records. Use PECOS public enrollment information and NPPES to check name variations, organization identifiers, and locations.
- Follow the applicable filing trail. For a nonprofit, search IRS records by EIN and review its Form 990 and Schedule H. If a public company appears in the chain, search its name in EDGAR and examine filings for subsidiaries or transactions.
- Keep periods separate. Compare the dates on each record. A current dataset release, an owner effective date, and an older tax-year filing are not one synchronized ownership snapshot.
- State exactly what the record shows. For example: “CMS lists X as an owner in its May 2026 self-reported dataset.” Claim ultimate ownership only when the records establish the intervening legal relationships.
