Reported by CALIFORNIA AG filing
Children's Hospital Los Angeles inadvertently transmitted confidential health information, including names, addresses, medical record numbers, dates of birth, and service descriptions, to the wrong insurance payor on November 29, 2017. The hospital contacted the payor, confirmed deletion of the data, updated records, and reinforced staff education. No evidence of misuse was found.
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.
