Flags in public data over time
California providers with any flag and with high-severity flags, from saved refresh snapshots. Each provider is counted once per series. Lead, not proof.
Only saved dates are shown; missing weeks are not counted as zero. Changes can reflect source coverage or rule updates, not changes in wrongdoing.
How to report to OIG
Check the source records and document supported concerns before reporting to the HHS Office of Inspector General. A flag alone is not evidence of wrongdoing. Lead, not proof.
