Section F.2 / In context

Where this filing sits in California and in 2026

OCR classifies the incident as improper disposal, with the breached information held in paper records or films. Improper Disposal is the type recorded on 8 of the 777 California filings (1%) and on 0% of all filings submitted in 2026. Paper/Films appears on 15% of California filings.

A business associate is recorded as present on the filing, as it is on 33% of California filings. At 16,545 individuals the breach is 4.7 times the California median filing of 3,553 and 4.1 times the national median of 4,000 across all 7,927 filings. It sits in the 10,000 to 99,999 band, which holds 1,950 filings.

As of 10 September 2026 the case is listed by HHS OCR under Cases Currently Under Investigation. OCR has not published a closing summary, so this page is limited to the fields on the filing itself; the archive entry that follows a closed investigation usually adds a short account of what was exposed and what the entity did afterwards.

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 16,545 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 $2.65M; the 2026 edition's $192 gives $3.18M. Both are modelled estimates with the method shown, not costs disclosed by Regional Center of Orange County. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.5 times the sector average.

16,545 x $192

Method: individuals affected, as reported by Regional Center of Orange County 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.

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 10 September 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.
