About this data

Every number on this site comes from public files published by the Centers for Medicare & Medicaid Services (CMS) in its Provider Data Catalog, the data behind Medicare's Care Compare. This page lists the files, what we do with them, and their limits.

The files

"National" files are held in full so state and U.S. averages can be calculated. The deficiency file is held for the pilot states only.

What we do with the data

• We show it as published. Ratings, counts and dates are copied from the CMS files. When CMS has no value, the page says "Not available" and shows the CMS footnote that explains why. We never estimate or fill in a missing value.
• Sentences are templates. The sentences on facility pages are fixed patterns filled in with CMS values, such as "CMS reported 4 of 8 mortality measures for this hospital; none were worse than the national rate."
• Averages. A state or U.S. average is the plain mean of the value across all facilities in the CMS file that have it. U.S. averages include territories. The number of facilities behind each average is shown next to it.
• Deficiencies. Nursing home pages list health deficiencies with an inspection date on or after Sep 30, 2023, three years before the deficiency file's release date.
• Names. CMS lists many hospital names in capital letters. We show them in ordinary capitalization and print the exact CMS spelling in the facility details.
• Cities. Cities come from facility addresses. Spellings that differ only in form (such as "Ft" and "Fort") are combined.
• Sorting. City lists are sorted by CMS overall star rating, then by name. We do not create our own scores or rankings.

Limits

• Measures cover past periods, often ending a year or more before release.
• A facility that closed or lost certification drops out of the files; we do not keep pages for facilities that are no longer listed.
• CMS data describe facilities, not individual doctors, units or services.
• The files can contain errors. If a facility's data look wrong, the facility can raise it with CMS; you can also tell us if our page does not match the CMS file.

*

For Maryland hospitals, no data are available to calculate a PSI 90 measure result; therefore, no performance decile or points are assigned for Domain 1 and the Total HAC score is dependent on the Domain 2 score.

1

The number of cases/patients is too few to report.

2

Data submitted were based on a sample of cases/patients.

3

Results are based on a shorter time period than required.

4

Data suppressed by CMS for one or more quarters.

5

Results are not available for this reporting period.

6

Fewer than 100 patients completed the CAHPS survey. Use these scores with caution, as the number of surveys may be too low to reliably assess facility performance.

7

No cases met the criteria for this measure.

8

The lower limit of the confidence interval cannot be calculated if the number of observed infections equals zero.

9

No data are available from the state/territory for this reporting period.

a

Maryland hospitals are waived from receiving payment adjustments under the Program.

**

This value was calculated using data reported by the hospital in compliance with the requirements outlined for this program and does not take into account information that became available at a later date.

10

Very few patients were eligible for the CAHPS survey. The scores shown reflect fewer than 50 completed surveys. Use these scores with caution, as the number of surveys may be too low to reliably assess facility performance.

11

There were discrepancies in the data collection process.

12

This measure does not apply to this hospital for this reporting period.

13

Results cannot be calculated for this reporting period.

14

The results for this state are combined with nearby states to protect confidentiality.

15

The number of cases/patients is too few to report a star rating.

16

There are too few measures or measure groups reported to calculate a star rating or measure group score.

17

This hospital's star rating only includes data reported on inpatient services.

18

This result is not based on performance data; the hospital did not submit data and did not submit an HAI exemption form.

19

Data are shown only for hospitals that participate in the Inpatient Quality Reporting (IQR) and Outpatient Quality Reporting (OQR) programs.

20

State and national averages do not include Veterans Health Administration (VHA) hospital data.

21

Patient survey results for Veterans Health Administration (VHA) hospitals do not represent official HCAHPS results and are not included in state and national averages.

22

Overall star ratings are not calculated for Department of Defense (DoD) hospitals.

23

The data are based on claims that the hospital or facility submitted to CMS. The hospital or facility has reported discrepancies in their claims data.

24

Results for this Veterans Health Administration (VHA) hospital are combined with those from the VHA administrative parent hospital that manages all points of service.

25

State and national averages include Veterans Health Administration (VHA) hospital data.

26

State and national averages include Department of Defense (DoD) hospital data.

27

Retired

28

The results are based on the hospital or facility's data submissions. CMS approved the hospital or facility's Extraordinary Circumstances Exception request suggesting that results may be impacted.

29

This measure was calculated using partial performance period data due to a CMS-approved exception.

Nursing home footnote codes

From the CMS Nursing Home Data Dictionary, Table 15 (updated September 2026).

1

Newly certified nursing home with less than 12-15 months of data available or the nursing home opened less than 6 months ago, and there were no data to submit or claims for this measure.

2

Not enough data available to calculate a star rating.

6

This facility submitted data that did not meet the criteria required to calculate a staffing measure.

7

CMS determined that the percentage was not accurate, or data suppressed by CMS for one or more quarters.

9

The number of residents or resident stays is too small to report. Call the facility to discuss this quality measure.

10

The data for this measure is missing or was not submitted. Call the facility to discuss this quality measure.

13

Results are based on a shorter time period than required.

14

This nursing home is not required to submit data for the Skilled Nursing Facility Quality Reporting Program.

18

This facility is not rated due to a history of serious quality issues and is included in the special focus facility program.

20

The accuracy of the data for this rating could not be validated by CMS.

21

The accuracy of the data for this measure could not be validated by CMS.

22

The street address for this facility could not be matched to latitude/longitude coordinates. Therefore, the latitude/longitude coordinates are based on the facility's zip code.

23

This facility did not submit staffing data.

24

This facility reported a high number of days without a registered nurse onsite.

25

The accuracy of the staffing data for this measure could not be validated by CMS.

26

This facility did not submit staffing data or submitted staffing data that is considered to be invalid for the purpose of calculating turnover. This measure will receive the minimum points for calculating the overall staffing score and rating.

27

This facility submitted staffing data that did not meet the criteria required to calculate a turnover measure. This measure will be excluded from the staffing rating and the staffing score will be rescaled.

28

This is an annual measure. Data for individual quarters is not available.

29

This was a Risk-Based Survey. Unlike a standard inspection, a Risk-Based inspection involves a shorter visit with a smaller inspection team and is only given to higher performing facilities.
