Reported by CALIFORNIA AG filing
Eureka Internal Medicine (CA) reported to HHS OCR on 2014-03-04 an Improper Disposal breach affecting 3,534 individuals. Breached information was located on Paper/Films. No business associate was involved. No further detail is available from the HHS web description.
Affected (this filing): 3,534
Eureka Internal Medicine experienced a data breach between September 25 and October 9, 2013, when a janitorial service mixed patient paper recycling containing PII and PHI with regular trash instead of using a locked shredding bin. The breach involved names, SSNs, insurance info, and medical records. No specific count of affected individuals was disclosed, though the firm assessed the likelihood of unauthorized access as very low.
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.
