Hospitals registered with Medicare · the federal government’s own files, read as you ask

The hospitals near a ZIP,
as Medicare rates them.

The Centers for Medicare & Medicaid Services (CMS) publishes how the hospitals registered with Medicare did on the things it measures. Give this page a ZIP code, a city and state or a name, and it lists the hospitals nearest first, each with CMS’s overall star rating, whether it has an emergency department and how long patients typically spent in it, how its infections compare with the national benchmark, and what patients said in the national survey. The comparison is free to run, for any ZIP code you enter.

Nothing is restated. The stars, the categories and the footnotes are CMS’s own; a rating CMS did not give reads “Not available” with CMS’s reason, never an empty row of stars; and every figure carries the months it was measured over. Open a hospital for every measure, or put two or three side by side.

Not medical advice, and not a recommendation of any hospital. In an emergency, call 911.

The desk

A ZIP in. The hospitals near it, with Medicare’s figures, out.

A five-digit ZIP lists the nearest hospitals first. A city and state (Boston, MA) lists that city’s; anything else is looked for in hospitals’ names.

Hospitals

ready

Nothing has been read yet. A search reads CMS’s list of hospitals once, then, for the hospitals shown, three of its files.

The overall rating: one to five stars and the number, or “Not available” with CMS’s footnote.
The type and ownership CMS records, and whether it lists emergency services.
The median time patients spent in the emergency department, against CMS’s national and state medians.
Infections: six measures, counted in CMS’s own comparison with the national benchmark.
The patient survey summary stars.

Reading a result

What each line says, and what it does not.

Overall rating: CMS’s Overall Hospital Quality Star Rating: one to five stars that summarise a hospital’s results in five groups of measures — mortality, safety of care, readmission, patient experience, and timely and effective care. More stars mean better results on those measures. A hospital’s own view shows how many measures in each group it reported.
“Not available”: CMS gives many hospitals no star rating — most often because they report too few measures, and never for military hospitals. That is not a low score. The line under it is CMS’s own footnote, numbered as CMS numbers it.
Time in the emergency department: Measure OP-18b: the median number of minutes between arriving at the emergency department and leaving it, for patients who were sent home (not admitted, not transferred, not psychiatric patients). Half of the sampled visits were shorter and half longer. It is a figure for twelve past months — not the wait tonight. Beside it are the medians CMS publishes for the nation and the state, and for hospitals with a similar number of emergency visits.
Infections: For six infections a patient can get in hospital, CMS says whether the hospital is “Better than the National Benchmark”, “No Different than National Benchmark” or “Worse than the National Benchmark”. A list counts those words; a hospital’s own view shows each infection with its ratio, its interval and the counts behind it.
Patient survey: HCAHPS, the national survey of adults recently discharged from a hospital. The summary star rating combines the survey’s topics; the number of completed surveys is printed beside it, because a rating from few surveys says less.
Distance: A straight line, in miles, between two points the Census Bureau publishes: its point for the ZIP you typed and its point for the hospital’s ZIP, each inside its area, at or near the middle. It is not a driving distance and not measured from your address; within one ZIP it says only that.

Elsewhere in the Health room: RX lists doctors’ practices near you, Facilities lists the other kinds of Medicare-certified facility, and Trials finds clinical studies recruiting nearby.

Method

One live source. Here is all of it.

The source

Every figure on this page comes from the Provider Data Catalog of the Centers for Medicare & Medicaid Services (data.cms.gov/provider-data), the files behind Medicare’s own Care Compare. Six files about hospitals are read, by their catalog identifiers:

Hospital General Information (xubh-q36u): name, address, type, ownership, emergency services and the overall rating.
Timely and Effective Care (yv7e-xc69): the emergency-department measures and others.
Patient survey (HCAHPS) (dgck-syfz).
Healthcare Associated Infections (77hc-ibv8).
Complications and Deaths (ynj2-r877) and Unplanned Hospital Visits (632h-zaca), in a hospital’s own view.

Beside them: CMS’s national files for the same measures, its state file for the emergency-department measures, and its Footnote Crosswalk, which is where the words of every footnote come from.

How fresh it is

CMS republishes these files from time to time. When this page was built, on 7 October 2026, the catalog gave 13 August 2026 as the release date of the first four files and 30 September 2026 for the last two; under every result the page prints the release date the catalog gives at that moment. Each figure’s own measurement period is printed beside it — the periods differ from measure to measure and are a year or more old by design.

CMS does not let a web page read its catalog directly, so a small relay on this site asks for you. The relay keeps each answer for twelve hours. If CMS is slow, down or refusing, the page shows the copy the relay last read — up to thirty days old — marked “Not read just now” with its age and the reason; with no copy, it says what failed and shows nothing in its place.

Each measure, in a sentence

Overall rating. One to five stars summarising a hospital’s reported measures in five groups: mortality, safety of care, readmission, patient experience, timely and effective care.
OP-18b. Median minutes from emergency-department arrival to departure for patients discharged from the emergency department; lower is shorter.
OP-22. The percentage of patients who left the emergency department before being seen.
Emergency department volume. CMS’s own band for how many emergency visits a hospital has: low, medium, high or very high.
Infections (HAI-1 to HAI-6). Central-line bloodstream infections, catheter-associated urinary tract infections, surgical-site infections after colon surgery and after abdominal hysterectomy, MRSA bloodstream infections and C. difficile: each as a standardized infection ratio — infections observed divided by infections predicted — against a national benchmark of 1.
HCAHPS star ratings. One to five stars for each topic of the patient survey (nurses, doctors, medicines, discharge information, cleanliness, quiet, the overall rating patients gave, and whether they would recommend the hospital) and a summary of them.
Complications and deaths. Deaths within 30 days for heart attack, heart failure, pneumonia, COPD, stroke and bypass surgery; complications after hip or knee replacement; and patient-safety indicators — each with CMS’s comparison with the national rate where it makes one.
Unplanned hospital visits. Readmissions within 30 days, days spent back in hospital, and visits after outpatient procedures.

The distance

CMS’s list gives a hospital’s address but no coordinates. This page ships one table of its own: the U.S. Census Bureau’s 2026 Gazetteer file of ZIP Code Tabulation Areas — 33,791 areas, each with the point the Bureau publishes for it. A distance is the straight line between your ZIP’s point and the hospital’s ZIP’s point. On 7 October 2026, 136 of the 5,419 hospitals were listed under a ZIP that is not such an area (a PO-box or single-building ZIP). For those the street address CMS gives was put to the Census Geocoder: 109 were placed, and their distances say “to its street address”; the other 27 are listed without a distance, by name, when their ZIP begins with the same three digits as yours.

What the ratings do not measure, and what this page does not know

They rate hospitals, not doctors, departments or a particular treatment, and they do not say what will happen to you.
The emergency-department time is a median over twelve past months for patients sent home. It is not a live wait, and not the time to be seen.
Nothing here covers prices, insurance networks, visiting, or whether a hospital treats a given condition.
CMS gives no overall rating to a large share of hospitals — 2,245 of the 5,419 on its list on 7 October 2026 — among them most critical access hospitals and every psychiatric, children’s and Department of Defense hospital. A hospital without stars has not been rated low.
Veterans Health Administration and Department of Defense hospitals report differently; CMS’s footnotes say where their results are, or are not, part of a national figure.
The list is the hospitals registered with Medicare. A hospital that is not, or that opened or closed since CMS’s last release, is not shown correctly.
This page does not order hospitals by quality. A ZIP search is in order of distance; any other search is alphabetical.

Where a search goes

A ZIP, a city or a name you type is used in your browser only: the whole list of hospitals is read, and the search is made here. This site’s relay is asked for the files of the hospitals shown, by their CMS numbers, and for the medians of their states — which is as near as this site comes to learning what you searched for; CMS sees this site’s server, never you. Nothing is stored on your device. The address changes only when you open a hospital or a comparison (it then holds CMS’s hospital numbers); a search enters the address only if you copy its link, and the site’s analytics may record an address as it stands. More in the legal page.
