Hood River Dental: 16,609 individuals, Oct 2026.

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 65 of the 123 Oregon filings (53%) and on 86% of all filings submitted in 2026. Network Server appears on 34% of Oregon filings.

No business associate is recorded on the filing; 23% of Oregon filings do involve one. At 16,609 individuals the breach is 6.8 times the Oregon median filing of 2,459 and 4.1 times the national median of 4,013 across all 8,092 filings. It sits in the 10,000 to 99,999 band, which holds 1,996 filings.

As of 12 November 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.

Oregon's breach notification statute (ORS 646A.600 et seq.) requires notice to affected residents as soon as practicable but no later than 45 days after discovery. Its attorney general threshold: 250 or more Oregon 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 16,609 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 $2.66M; the 2026 edition's $192 gives $3.19M. Both are modelled estimates with the method shown, not costs disclosed by Hood River Dental. 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.
