What Is CMS Care Compare?

CMS Care Compareis Medicare’s official tool for comparing the quality of certified healthcare facilities. It covers nursing homes, home health, hospice, dialysis, ambulatory surgical centers, and hospitals — 14,699 nursing homes alone — each with star ratings and inspection data drawn from CMS’s own records.

What Care Compare is

Care Compare is the consumer-facing front end for the regulatory data CMS already collects when it certifies and inspects healthcare facilities. Instead of leaving that data buried in agency files, CMS turns it into side-by-side comparisons: how a facility scores on inspections, how it staffs, and how its patient outcomes look against peers.

It replaced a set of older, separate “Compare” sites (Nursing Home Compare, Hospital Compare, and others), unifying them under one banner so the public has a single place to look up certified providers.

The facility types it covers

Nursing homes

14,699 certified facilities — ratings, staffing, inspections, ownership.

Home health agencies

12,392 certified agencies — quality of patient care and services offered.

Hospices

6,943 certified hospices — ownership and CAHPS quality measures.

Dialysis facilities

7,557 ESRD facilities — five-star ratings and chain ownership.

Ambulatory surgical centers

5,611 ASCs — the ASC quality measures for same-day surgery.

Hospitals & more

Hospitals, long-term acute care, and inpatient rehab — all under one comparison hub.

How the star ratings work

For several facility types, CMS rolls dozens of underlying measures into a single overall rating from one to five stars. For nursing homes, that blends health-inspection results, staffing, and quality measures; for dialysis and home health, it blends the relevant clinical outcomes. The star is a useful summary, but the underlying measures — inspection deficiencies, staffing hours, outcome rates — are what tell the real story, which is why Fonteum surfaces them, not just the headline number.

How Fonteum mirrors Care Compare

Fonteum builds on the same open CMS datasets but wraps every figure in provenance: the source dataset, the snapshot date, and a link back to the federal file. Facilities can be cross-referenced against the OIG exclusion list and the rest of the federal provider graph by NPI and CMS Certification Number. The result is a traceable, comparable view across facility types — each number you can follow to its origin.

Frequently asked questions

What is CMS Care Compare?
CMS Care Compare is the official tool the Centers for Medicare & Medicaid Services publishes so the public can compare the quality of Medicare-certified healthcare facilities and providers. It consolidates inspection results, star ratings, staffing, and outcome measures for each facility into a single comparison, drawn from CMS's own regulatory data.
What facility types does Care Compare cover?
Care Compare spans the main Medicare-certified facility types, including nursing homes (14,699), home health agencies (12,392), hospices (6,943), dialysis facilities (7,557), ambulatory surgical centers (5,611), and hospitals, plus long-term and inpatient-rehab facilities.
What is the CMS star rating?
For several facility types, CMS condenses many underlying measures into an overall star rating from one to five, where five is best. The rating blends inputs like health-inspection results, staffing, and quality measures so the public has a single, comparable summary — though the underlying measures matter more than the headline star.
Is Care Compare data free and public?
Yes. CMS publishes the underlying Care Compare datasets as open government data on source-specific schedules. That is why independent platforms can mirror and analyze them. Fonteum republishes loaded records and displays available CMS source and snapshot metadata on supported fields.
How often is Care Compare updated?
CMS publishes Care Compare datasets on source-specific schedules, often monthly or quarterly. A Fonteum page shows the loaded source or observation date when the record supplies it; that field can be absent. Publisher cadence does not prove Fonteum loaded a newer release.
How is Fonteum's Care Compare different from Medicare's?
Fonteum draws on the same CMS source data and displays available source, dataset, and snapshot metadata on supported figures. Facility records can also be cross-referenced against the OIG exclusion list and other loaded federal sources. The goal is a traceable, comparable view across supported facility types, not a marketing surface.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
