Section F.2 / In context
Where this filing sits in California and in 2013
OCR classifies the incident as theft, with the breached information held in a laptop. Theft is the type recorded on 172 of the 776 California filings (22%) and on 48% of all filings submitted in 2013. Laptop appears on 9% of California filings.
No business associate is recorded on the filing; 33% of California filings do involve one. At 56,500 individuals the breach is 16 times the California median filing of 3,553 and 14 times the national median of 4,000 across all 7,884 filings. It sits in the 10,000 to 99,999 band, which holds 1,938 filings.
As of 28 August 2026 the case is listed in the HHS OCR breach portal archive. OCR's closing summary of the case is reproduced in full below.
California's breach notification statute (Cal. Civ. Code 1798.82) requires notice to affected residents within 30 calendar days of discovery (effective 1 January 2026, SB 446). Its attorney general threshold: more than 500 California residents. The HIPAA Breach Notification Rule ran alongside it: notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery, which is the clock that put this filing on the portal.
Multiplying 56,500 individuals by IBM's $160 customer-PII cost per record (Cost of a Data Breach 2025, the figure the site's calculator uses) gives a modelled $9.04M; the 2026 edition's $192 gives $10.8M. Both are modelled estimates with the method shown, not costs disclosed by Stanford School of Medicine & LP Children Hosp, Privacy Manager Breach. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 1.6 times the sector average.
Section F.3 / OCR closing summary
The portal's archived description, in full
Written by the Office for Civil Rights when the case was closed and reproduced verbatim from the HHS export.
The covered entity (CE), Stanford School of Medicine (SOM) and Stanford Children's Hospital (SCH)(formerly Lucile Packard Children's Hospital), reported that on January 9, 2013, a SOM workforce member's password-protected laptop was stolen from the workforce member's vehicle. The CE reported that the electronic protected health information (ePHI) stored on the laptop was unencrypted. The ePHI of approximately 56,500 individuals may have been affected by this incident. The ePHI included demographic and clinical information related to SCH patient care and SOM research. Following this incident, the CE contacted law enforcement, notified the affected individuals, offered identity protection services to the affected individuals, established a call center to assist affected individuals with questions or concerns, and submitted notification to the media and HHS. The CE reported that there was no evidence of unauthorized access to the ePHI stored on the laptop. As a result of the breach and OCR's corresponding investigation, the CE sanctioned the workforce member for violating HIPAA policies, and retrained workforce members on data security policies. SCH implemented enhanced administrative and technical safeguards to ensure secure email communications; and. The CE also initiated plans to implement an improved risk management process.

Method: individuals affected, as reported by Stanford School of Medicine & LP Children Hosp, Privacy Manager Breach to HHS, multiplied by IBM's customer-PII cost per record (Cost of a Data Breach 2025 Figure 6 and the 2026 edition). No cost has been disclosed by the entity for this filing; the figure is a planning estimate, not a fact about the breach. IBM's per-record figures come from mid-volume breaches and IBM cautions against applying them to breaches involving millions of records; the site's per-record page explains where the multiplication holds and where it breaks down.
Context: IBM's average cost of a healthcare breach is $6.64M in the 2026 report ($7.42M in 2025); the global average across all sectors was $4.44M in 2025.

Portal: ocrportal.hhs.gov breach report. Statutory basis: HITECH Act section 13402(e)(4): the Secretary must post a list of breaches of unsecured protected health information affecting 500 or more individuals. Breaches affecting fewer than 500 individuals are reported to OCR annually and are not posted, so they are not on this register. Status wording follows the portal's two tabs ("Cases Currently Under Investigation" and "Archive") as of 28 August 2026; a filing moves to the archive when OCR closes the case. Modelled costs on this site are a method applied to the reported count, using IBM Cost of a Data Breach per-record figures, and are never a cost disclosed by the entity.
