Federal penalties

The wording in the third column is CMS’s own plain-language summary of the federal rule that was cited, not a description of what happened. This table shows every one of the 4 citations at actual-harm level or above, plus the 6 most recent of the rest. The other 30 are in the CMS file linked below.
How to read scope and severity
Every citation gets a letter from A to L. The letter carries two things at once: how serious the problem was, and how many residents it reached.
| Severity | Isolated | Pattern | Widespread |
|---|---|---|---|
| Immediate jeopardy to resident health or safety | J | K | L |
| Actual harm | G | H | I |
| No actual harm, potential for more than minimal harm | D | E | F |
| No actual harm, potential for minimal harm | A | B | C |
“Immediate jeopardy” is CMS’s term for a situation that has caused, or is likely to cause, serious injury, harm, impairment or death. It requires the home to act at once.
What this page does not tell you
- A citation is an inspector’s finding against a federal rule. It is not a court judgment, and the facility may be disputing it. Citations marked “under dispute” above are in CMS’s formal review process.
- Citation counts partly reflect how often a home was inspected and how many complaints were filed about it. A home with more citations has not automatically given worse care than one with fewer.
- Bigger homes have more residents, more staff and more inspections, so they tend to accumulate more citations.
- None of this says anything about the care any one resident received. A home with a clean record can still fail somebody, and a home with a bad record can be caring for your mother well.
- This is a snapshot. CMS updates these files monthly, and the figures here are from the file dated August 1, 2026.
