Before you start: what the public data can and cannot do
CMS — the federal agency that runs Medicare and Medicaid — publishes a large amount of data about every certified nursing home in the country: star ratings, inspection results, staffing levels, penalties, and ownership. That record is powerful for narrowing a list and spotting patterns, and it is the backbone of this workflow.
But it has limits, and knowing them up front keeps you from over-reading it. The data is a dated snapshot, not a live feed, so it can lag recent changes. Star ratings summarize past performance, not the care a specific resident will receive today. And a missing value usually means CMS did not report it — often because a facility was too small or too new for reliable measurement — not that the answer is bad. Treat the public record as the start of your research, not the end of it.
Step 1 — Identify the facility and confirm it is CMS-certified
Start by finding the exact facility. Search by name, city, county, state, ZIP, or CMS certification number (CCN) — the unique federal ID that follows a facility even if it is renamed or sold. Matching on the CCN is the surest way to know you are looking at the right building.
Confirming the facility appears in the CMS data at all is itself a check: a certified nursing home is one CMS inspects and holds to federal standards. A facility that is not Medicare/Medicaid-certified will not appear, and that is worth knowing before you go further.
Step 2 — Read all four CMS ratings together, not just the overall star
CMS assigns an overall one-to-five-star rating, but it is built from three separate component ratings: the health-inspection rating, the staffing rating, and the quality-measures rating. Read all four side by side.
This matters because of how CMS builds the number. It starts from the health-inspection rating and then adjusts it using staffing and quality measures, so a facility with a middling inspection record can be carried upward by strong staffing or quality-measure scores. A strong overall number is therefore not the same as a clean inspection history, and when two facilities show the same overall star, the components are usually where the real difference lives.
One structural point governs every comparison that follows: CMS grades the health-inspection rating relative to other facilities in the SAME state, and inspections are carried out by each state's own survey agency. Two facilities in different states holding the same star have been measured against different peer groups under different agencies. Compare within a state, not across state lines.
Step 3 — Look closely at staffing
Staffing is the input most consistently linked to day-to-day care, and CMS reports it in detail: registered-nurse hours, total nurse staffing, and staff turnover. The reported hours come from payroll-based data rather than facility self-report, and the staffing measures are case-mix adjusted — expressed against how much care that facility's residents actually need, so a facility serving higher-acuity residents is expected to staff accordingly. Turnover is reported separately and is not a case-mix-adjusted figure.
Pay attention to registered-nurse coverage specifically, and to weekend staffing where CMS reports it — thin weekend coverage is a common gap the single staffing star can obscure.
Steps 4–5 — Read the inspection citations and their severity
Every certified facility is surveyed on a roughly annual cycle, plus whenever a complaint triggers an investigation. CMS records each deficiency cited, along with its scope and severity and whether it came from a routine survey or a complaint.
Check the date of the most recent survey before you read the citations. A facility showing no recent findings may have had a strong survey — or may simply not have been surveyed lately, and the two records look alike until you check the dates. CMS also weights recent surveys more heavily than older ones when it calculates the inspection rating.
Do not just count citations — read their severity. A facility with several low-level, promptly-corrected paperwork deficiencies is a very different picture from one with a smaller number of high-severity citations that placed residents in jeopardy. Complaint-driven and infection-control citations are especially worth reading in full. Our guide on reading inspection citations explains the scope-and-severity grid.
Steps 6–7 — Review federal penalties and payment denials
When problems are serious or repeated, CMS can impose federal penalties: fines and denials of payment for new admissions. Both are recorded, with dates and amounts.
A single old fine is not necessarily alarming; a pattern of recent penalties, or a denial of payment for new admissions, is a stronger signal that CMS found significant problems. Read them chronologically to see whether issues are recent or historical.
Step 8 — Check for the CMS abuse icon
CMS flags a facility with a special abuse icon when recent inspections cited abuse, or the potential for abuse, that harmed or could have harmed a resident. It is less rare than people expect — roughly one facility in ten carries it nationally, and our report on the abuse icon measures the current share and how sharply it varies by state.
Read presence and absence differently. When the icon is present, something specific and documented sits behind it, and you should read the underlying citations before anything else. Its absence is the ordinary case rather than a distinction, and says nothing about the rest of a facility's record — a facility can carry serious inspection findings, federal penalties, or thin staffing while carrying no icon.
Step 9 — Research ownership
CMS reports the ownership behind each facility, and grouping facilities by owner can be revealing: it shows what else an operator runs, in how many states, and how their other facilities score. Ownership is a structural fact, not a quality signal on its own — but if an operator's portfolio shows consistent patterns, that context is useful. Use the ownership pages to see the whole footprint.
Step 10 — Add the state survey record
CMS data is national, but nursing homes are also overseen by a state survey agency, which often publishes its own inspection detail and complaint records. After the federal record, checking your state agency can add local context CMS does not surface — recent complaints, licensure actions, or narrative inspection reports.
Steps 11–13 — Visit, ask structured questions, and record what you see
The data narrows your list; a visit decides it. Go at different times, including a weekend or an evening, when staffing is often thinnest. Notice the things data cannot capture: whether call lights are answered, whether residents are up and engaged, whether the building smells clean, how staff speak to residents.
Bring a consistent set of questions to every facility so you can compare answers, not impressions: current registered-nurse-to-resident ratios, staff turnover, how care plans are set and reviewed, how concerns and complaints are handled, and what has changed since the last inspection. Write down what you observe at each place the same day — memory blurs quickly across multiple tours.
Step 14 — Compare your finalists on the same fields
Finally, put two or three finalists side by side on identical criteria — the four CMS ratings, staffing, recent inspection severity and its date, penalties, and your own visit notes. Comparing like-for-like keeps a single strong number from dominating the decision. Our comparison tool lets you line facilities up on the CMS fields; add your visit notes alongside.
Keep the comparison inside one state wherever the choice allows it. Because the inspection rating is graded against other facilities in the same state, a cross-state comparison mixes real differences in care with differences in state survey practice that the public data cannot separate.
A printable research checklist
Use this as a one-page checklist per facility: (1) Confirmed CMS certification and matched the CCN. (2) Recorded all four CMS ratings — overall, health inspection, staffing, quality measures. (3) Noted registered-nurse and weekend staffing. (4) Checked the date of the most recent survey, then read the citations and their severity, not just the count. (5) Checked federal penalties and their dates. (6) Checked for payment denials. (7) Checked for the CMS abuse icon. (8) Reviewed ownership and the operator's other facilities. (9) Checked the state survey agency. (10) Visited at least once, ideally off-hours. (11) Asked the same structured questions everywhere. (12) Wrote observations the same day. (13) Compared finalists on identical fields. (14) Verified current details on CMS Care Compare before deciding.
A worked example
Suppose two facilities both show a four-star overall rating. Facility A's components are 3-star health inspection, 5-star staffing, 4-star quality measures; Facility B's are 4/4/4 with a federal fine two years ago and none since. On the overall star alone they look identical. Reading deeper, A leans on strong staffing to offset a weaker inspection history, while B is more balanced with an old, resolved penalty. Neither is 'better' in the abstract — but now your visit has a focus: probe A's inspection history and current staffing stability, and ask B what changed after the penalty. That is what the workflow is for: turning a single number into specific questions.
