Section F.2 / In context
Where this filing sits in Oklahoma and in 2011
OCR classifies the incident as theft, with the breached information held in a laptop and paper records or films. Theft is the type recorded on 12 of the 80 Oklahoma filings (15%) and on 62% of all filings submitted in 2011. Laptop appears on 9% of Oklahoma filings.
No business associate is recorded on the filing; 33% of Oklahoma filings do involve one. At 132,940 individuals the breach is 35 times the Oklahoma median filing of 3,849 and 33 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.
Oklahoma's breach notification statute (Okla. Stat. tit. 24, 161 et seq.) requires notice to affected residents without unreasonable delay. Its attorney general threshold: 500 or more Oklahoma 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 132,940 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 $21.3M; the 2026 edition's $192 gives $25.5M. Both are modelled estimates with the method shown, not costs disclosed by Oklaholma State Dept. of 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.

Method: individuals affected, as reported by Oklaholma State Dept. of 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
Oklahoma statute and the HIPAA rule
State notification statute
Oklahoma: Okla. Stat. tit. 24, 161 et seq.
amended by SB 626 (effective 1 January 2026)
- Notice to individuals
- Without unreasonable delay
- Attorney general threshold
- 500 or more Oklahoma residents (No later than 60 days after providing notice to residents)
- Private right of action
- No: No PROA; enforcement is exclusive to the Oklahoma Attorney General
- Penalty
- Up to $150,000 per breach; reduced or waived where reasonable safeguards are demonstrated
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.
