The rules applied, and where they come from

Every rule is transcribed from its official source: the excerpt is verbatim, with the date it was read and a fingerprint of the page. When a page changes, the rule is read again.

What the agency says it enforces

An enforcement notice is not a rule: it says how the agency applies the rule today. The service reports it separately, with its source and the date it was read.

CMS data dictionary of the Revalidation Due Date List

The due date column is the previously assigned revalidation due date, blank when none was assigned. A past date in the list therefore does not show whether the provider has revalidated: the service returns date_passed, never a late status.

CMS data dictionary of the Revalidation Due Date List

The adjusted column is the next revalidation due date, blank when not yet assigned. When both dates are published, the service returns the earlier one as due_date and the other as later_due_date.
