Section F.2 / In context
Where this filing sits in California and in 2020
OCR classifies the incident as a hacking or IT incident, with the breached information held in email. Hacking/IT Incident is the type recorded on 398 of the 776 California filings (51%) and on 69% of all filings submitted in 2020. Email appears on 20% of California filings.
No business associate is recorded on the filing; 33% of California filings do involve one. At 199,548 individuals the breach is 56 times the California median filing of 3,553 and 50 times the national median of 4,000 across all 7,884 filings. It is one of 801 filings of 100,000 or more individuals.
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 199,548 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 $31.9M; the 2026 edition's $192 gives $38.3M. Both are modelled estimates with the method shown, not costs disclosed by PIH Health. Because the filing is above the roughly 100,000-record range in which the per-record figure is reliable, the result is an upper bound, not an estimate: fixed costs are spread across far more records at this scale.
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.
Today, the U.S. Department of Health and Human Services (HHS), Office for Civil Rights (OCR) announced a settlement with PIH Health, Inc. (PIH), a California health care network, over potential violations of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). The violations stem from a phishing attack that exposed unsecured electronic protected health information (ePHI), prompting concerns related to the Privacy, Security, and Breach Notification Rules under HIPAA.
OCR enforces the HIPAA Privacy, Security, and Breach Notification Rules (HIPAA Rules), which set forth the requirements that covered entities (health plans, health care clearinghouses, and most health care providers), and business associates must follow to protect the privacy and security of Americans' protected health information (PHI).
"Hacking is one of the most common types of large breaches reported to OCR every year," said OCR Acting Director Anthony Archeval. "HIPAA-regulated entities need to be proactive and remedy the deficiencies in their HIPAA compliance programs before those deficiencies result in the impermissible disclosure of patients' protected health information."
The settlement resolves an investigation that OCR conducted after receiving a breach report from PIH in January 2020. The breach report stated that in June 2019, a phishing attack compromised forty-five of its employees' email accounts, resulting in the breach of 189,763 individuals' unsecured ePHI. PIH reported that the ePHI disclosed in the phishing attack included affected individuals' names, addresses, dates of birth, driver's license numbers, Social Security numbers, diagnoses, lab results, medications, treatment and claims information, and financial information.
OCR's investigation found multiple potential violations of the HIPAA Rules, including:
• Failure to use or disclose protected health information only as permitted or required by the HIPAA Privacy Rule.
• Failure to conduct an accurate and thorough risk analysis of the potential risks and vulnerabilities to the confidentiality, integrity, and availability of ePHI held by PIH.
• Failure to notify affected individuals, the HHS Secretary, and the media of a breach of unsecured protected health information within 60 days of its discovery.
Under the terms of the resolution agreement, PIH has agreed to implement a corrective action plan that will be monitored by OCR for two years and paid a $600,000 settlement to OCR. Under the corrective action plan, PIH is obligated to take definitive steps toward resolving potential violations of the HIPAA Rules, including:
• Conducting an accurate and thorough risk analysis of the potential risks and vulnerabilities to the confidentiality, integrity, and availability of its ePHI.
• Developing and implementing a risk management plan to address and mitigate security risks and vulnerabilities identified in its risk analysis.
• Developing, maintaining, and revising, as necessary, its written policies and procedures to comply with the HIPAA Rules.
• Training its workforce members who have access to PHI on its HIPAA policies and procedures.

199,548 x $192
Method: individuals affected, as reported by PIH Health 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.

Section F.6 / Notification clock
California statute and the HIPAA rule
State notification statute
California: Cal. Civ. Code 1798.82
- Notice to individuals
- Within 30 calendar days of discovery (effective 1 January 2026, SB 446)
- Attorney general threshold
- More than 500 California residents (Within 15 calendar days after notifying affected consumers)
- Private right of action
- Yes: Under CCPA Civ. Code 1798.150 for breaches from failure to maintain reasonable security; $107-$799 per consumer per incident (CPI-adjusted from $100-$750, effective Jan 2025)
- Penalty
- CCPA civil penalties of $2,663 per violation, $7,988 per intentional violation (CPI-adjusted, effective Jan 2025); CCPA private right of action for security-failure breaches
The HIPAA Breach Notification Rule runs alongside the state statute: notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery.

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.
