Bishop Eye Center reported to HHS on 2022-04-07 a hacking/IT incident affecting 2,292 individuals. The breach resulted from a cyber-attack and compromised protected health information (PHI) from a network server, including names, dates of birth, addresses, Social Security numbers, and treatment information. In response, the center notified affected individuals, provided complimentary credit monitoring, implemented additional technical safeguards, and revised its policies.
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.
