Section F.2 / In context
Where this filing sits in Hawaii and in 2018
OCR classifies the incident as a hacking or IT incident, with the breached information held in a network server. Hacking/IT Incident is the type recorded on 13 of the 22 Hawaii filings (59%) and on 45% of all filings submitted in 2018. Network Server appears on 45% of Hawaii filings.
No business associate is recorded on the filing; 27% of Hawaii filings do involve one. At 40,800 individuals the breach is 2.8 times the Hawaii median filing of 14,369 and 10 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.
Hawaii's breach notification statute (HRS Ch. 487N) requires notice to affected residents without unreasonable delay. Its attorney general threshold: 1,000 or more Hawaii residents (written notice to the Office of Consumer Protection). 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 40,800 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 $6.53M; the 2026 edition's $192 gives $7.83M. Both are modelled estimates with the method shown, not costs disclosed by Greigh I. Hirata M.D. Inc, dba. Fetal Diagnostic Institute of the Pacific. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 1.2 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.
On August 30, 2018, the covered entity (CE), Fetal Diagnostic Institute of the Pacific, in Honolulu, Hawaii, reported that two of the computer servers on its system were affected by a ransomware attack, affecting 40,800 individuals. The types of protected health information (PHI) involved in the breach included demographic and clinical information. The CE found no evidence that patients' PHI was impermissibly disclosed or accessed. The CE provided breach notification to HHS, affected individuals, and the media. In response to the breach, the CE implemented new technical safeguards, including firewall and related protection services, antivirus and online threat active monitoring, and a tool for remote management of security patches and updates. The CE also retrained its workforce and implemented risk analysis and risk management plans as recommended by its security company. OCR obtained documentation including the CE's revised policies and procedures and its new employee orientation packet relevant to this breach investigation and obtained assurances that the CE implemented the corrective actions listed above.

Method: individuals affected, as reported by Greigh I. Hirata M.D. Inc, dba. Fetal Diagnostic Institute of the Pacific 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.
