Records desk / how to read a star

What a Medicare star rating does and does not measure

A Medicare home health star is a real number, computed by the federal government, published in a public file, and copied onto this desk without adjustment. It is also a narrow number. Families treat it as a verdict on a company. The file it comes from does not support that reading. This page sets out what the quality of patient care star measures, what the survey star beside it measures, and what neither one can tell you about the household you are trying to arrange care for.

Which star you are looking at

There are two stars on this desk, from two files, joined on CMS Certification Number and never blended. The quality of patient care star comes from Home Health Care Agencies 6jpm-sxkc. CMS publishes it as a single value from 1.0 to 5.0 in half-star steps, computed from a set of quality measures drawn from agency assessment and claims data. The patient survey star comes from Home Health Care Patient Survey (HHCAHPS) ccn4-8vby. It is a whole star from 1 to 5, computed by CMS from the Home Health Care CAHPS survey returned by an agency's patients. The survey period on the current record is 2025 Q1 to 2025 Q4.

This desk's star ratings file sorts on the quality star. The survey stars file sorts on the survey star and uses the quality star only as a tie-break. If you average them, you have left the record.

What the quality star does measure

The quality star is a summary of clinical process and outcome measures across an agency's Medicare home health patients in a reporting period. It is about skilled care delivered at home under a clinician's plan of treatment: nursing, therapy, and the related measures CMS scores. The official public tool with the same underlying data plus measure-level detail is Medicare Care Compare. Anything on this desk should match it. If it does not, the source is right and this desk is stale.

In the July 2026 release, pulled 2026-09-10, 50 Medicare-certified home health agencies have a street address inside the fifteen county St. Louis metro. 47 of them carry a quality star. The 3 that do not are left out of the sorted table rather than printed as zero, usually a volume question rather than a quality one. Agencies with too few cases in a measure are not scored on that measure. A missing star is not a hidden 1.0.

What it does not measure, even for a certified agency

A star covers only the agency's Medicare patients, not everyone it serves. An agency can do other work, including non-medical hours billed to a family, that never enters the quality file. Medicare covers home health services when a beneficiary meets its conditions. It does not pay for long-term personal care or homemaking on their own. A high quality star on the certified side does not travel with a companion sitting in the living room in the evening.

The reporting period sits behind the publication date. CMS refreshes these files quarterly. The star you are reading describes a window that has already closed. A recent change in staffing, ownership, or local management will not show until a later release. Check Care Compare before you act on a copied number.

The star is an agency-level average. It cannot tell you which clinician will be assigned, how the agency covers a sick day, or whether the person who did well with the last patient will do well with yours. Those questions have no row in 6jpm-sxkc. Ask them directly.

The other star is not a second vote on the same thing

The quality star and the survey star measure different things and often disagree, which is informative rather than contradictory. An agency can run a tight clinical operation that people find impersonal, or the reverse. In the current metro extract, 38 of the 47 star-rated agencies carry a survey star. 14 of those 38 hold the top mark of 5. No metro agency in this release holds a survey star of 1. The 9 agencies with no survey star are named on the survey file rather than scored zero, because CMS publishes no survey star when too few completed surveys fall in the period. That rule is the programme's, set out on the HHCAHPS site.

Do not treat a high quality star and a missing survey star as a mixed review. One is a clinical summary. The other is the presence or absence of enough returned surveys. They are not two readings of the same thermometer.

The category line the star cannot cross

Every star on this site belongs to a home health agency: an organisation certified by Medicare to deliver skilled clinical care at home. Nothing on the star table is a provider of personal care, companionship, homemaking, transportation, or dementia support sold as non-medical care at home. Medicare does not certify that category and CMS has never scored it. A company in that category has no star, and that is not a low score. It is the absence of a scoring system. The two-categories file explains the licensing line on both sides of the river.

If you are holding a quote for help after a hospital stay, you may need both categories at once: a certified agency visiting under a plan of treatment, and a separate non-medical arrangement for the hours Medicare will not pay. The discharge week is walked through at After the Hospital STL. The star on the certified agency does not grade the companion. For hiring on the unlicensed side, use Hire Caregiver STL and the identity checks on the walkthrough.

How to use a star without over-reading it

Use it as a federal summary of one category of work, for one payer's patients, in a closed reporting window. Compare it against the survey star without averaging them. Confirm the agency reports serving the zip code of the house in the zip file. Then ask the questions the file is silent on: who comes, who covers, who employs, who insures, what it costs, and how the contract ends. A star is a starting document. It is not the decision.
