Community Health Center, Inc.: 1,060,936 individuals, Jan 2025.

OCR classifies the incident as a hacking or IT incident, with the breached information held in an electronic medical record system and a network server. Hacking/IT Incident is the type recorded on 91 of the 144 Connecticut filings (63%) and on 81% of all filings submitted in 2025. Electronic Medical Record appears on 6% of Connecticut filings.

No business associate is recorded on the filing; 35% of Connecticut filings do involve one. At 1,060,936 individuals the breach is 212 times the Connecticut median filing of 5,000 and 265 times the national median of 4,000 across all 7,884 filings. It is one of 149 filings on the register of one million or more individuals.

As of 28 August 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.

Connecticut's breach notification statute (Conn. Gen. Stat. 36a-701b) requires notice to affected residents without unreasonable delay, no later than 60 days after discovery. Its attorney general threshold: all breaches (no minimum resident threshold). 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 1,060,936 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 $170M; the 2026 edition's $192 gives $204M. Both are modelled estimates with the method shown, not costs disclosed by Community Health Center, Inc.. 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.
