Section F.2 / In context
Where this filing sits in Connecticut and in 2022
OCR classifies the incident as unauthorized access or disclosure, with the breached information held in a network server. Unauthorized Access/Disclosure is the type recorded on 34 of the 144 Connecticut filings (24%) and on 16% of all filings submitted in 2022. Network Server appears on 44% of Connecticut filings.
No business associate is recorded on the filing; 35% of Connecticut filings do involve one. At 19,496 individuals the breach is 3.9 times the Connecticut median filing of 5,000 and 4.9 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.
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 19,496 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 $3.12M; the 2026 edition's $192 gives $3.74M. Both are modelled estimates with the method shown, not costs disclosed by Yale New Haven Hospital. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.6 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.
The covered entity (CE), Yale New Haven Hospital, reported that a file containing the protected health information (PHI) of 19,496 individuals was inadvertently uploaded to a public facing website. The PHI involved included names, telephone numbers, email addresses, diagnoses, and other treatment information. The CE notified HHS, affected individuals, the media, and provided substitute notice. In response to the breach, the CE implemented additional administrative, technical, and security safeguards, and retrained workforce members to better protect its PHI.

Method: individuals affected, as reported by Yale New Haven Hospital 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
Connecticut statute and the HIPAA rule
State notification statute
Connecticut: Conn. Gen. Stat. 36a-701b
- Notice to individuals
- Without unreasonable delay, no later than 60 days after discovery
- Attorney general threshold
- All breaches (no minimum resident threshold) (No later than the time notice is provided to affected residents)
- Private right of action
- No: Non-compliance is an unfair trade practice; only the AG enforces
- Penalty
- Up to $5,000 per willful violation under CUTPA, plus injunctive relief and restitution
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.
