Reported by CALIFORNIA AG filing
Sonoma Valley Hospital disclosed a data breach involving the accidental public posting of patient surgical service records (names, dates of service, procedures, surgeons, charges, insurance) on its website from Feb 14, 2013, to April 17, 2013. The hospital took the site down, completed an investigation, and notified affected patients under California SB 541. No SSNs or driver's licenses were exposed.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
