Section F.2 / In context

Where this filing sits in California and in 2015

OCR classifies the incident as theft, with the breached information held in a desktop computer. Theft is the type recorded on 172 of the 776 California filings (22%) and on 30% of all filings submitted in 2015. Desktop Computer appears on 8% of California filings.

A business associate is recorded as present on the filing, as it is on 33% of California filings. At 54,203 individuals the breach is 15 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 54,203 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 $8.67M; the 2026 edition's $192 gives $10.4M. Both are modelled estimates with the method shown, not costs disclosed by Molina Healthcare. 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.

A former employee of the covered entity's (CE) business associate (BA), CVS Health, impermissibly exfiltrated the CE's member information from its systems and saved the protected health information (PHI) onto his personal computer. The PHI involved in the breach included full names, member identification numbers, health card numbers, plan codes and states, and start and end dates. The breach affected approximately 54,203 individuals. The CE provided breach notification to HHS, affected individuals, and the media, and also provided substitute notification. The CE also offered individuals one year of free identity theft protection membership. As a result of this incident, the CE required the BA to improve safeguards by enhancing security for the BA's fraud management tool and databases containing PHI, and updating its security procedures. OCR reviewed the CE's policies, procedures, and/or documentation related to impermissible disclosures, safeguards, business associates, and breach notification and obtained assurances that the BA implemented the corrective actions listed above.

IBM 2026 customer PII, $192 per record

54,203 x $192

Method: individuals affected, as reported by Molina Healthcare 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)

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.
