Section F.2 / In context
Where this filing sits in Illinois and in 2015
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 201 of the 358 Illinois filings (56%) and on 21% of all filings submitted in 2015. Network Server appears on 43% of Illinois filings.
No business associate is recorded on the filing; 34% of Illinois filings do involve one. At 10,000 individuals the breach is 2.9 times the Illinois median filing of 3,403 and 2.5 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.
Illinois's breach notification statute (815 ILCS 530) requires notice to affected residents in the most expedient time possible and without unreasonable delay. Its attorney general threshold: more than 500 Illinois residents (private collectors); 250 for state agencies. 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 10,000 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 $1.60M; the 2026 edition's $192 gives $1.92M. Both are modelled estimates with the method shown, not costs disclosed by Pediatric Group LLC. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.3 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 21, 2015, an unknown entity hacked into the covered entity's (CE) electronic database utilizing a Crypto Locker computer virus, and the virus attached to some of the CE's Portable Document Format (PDF) files which contained patients' names, dates of birth, clinical information, and other personal identifiers. The virus then blocked the CE's access to the aforementioned PDF files and the CE received an email message demanding a $500.00 ransom in order to gain access to the locked PDF files. Approximately 10,000 individuals were affected by the breach. Upon discovering the breach, the CE conducted a breach risk assessment which indicated that there was a low overall probability that protected health information (PHI) was compromised, and therefore, breach notification to individuals and the media was not required. The CE reported the breach incident to the Internet Crime Complaint Center, a division of the Federal Bureau of Investigations. To prevent similar breaches from happening in the future, the CE retained a computer forensic firm to assist with the analysis of the ransomware incident, and installed anti-malware products on all its computers. The CE trained staff on its policies and procedures regarding Cyber Security Awareness. OCR obtained documented assurances that the CE implemented the corrective actions noted above.

Method: individuals affected, as reported by Pediatric Group LLC 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
Illinois statute and the HIPAA rule
State notification statute
Illinois: 815 ILCS 530
Personal Information Protection Act (PIPA)
- Notice to individuals
- In the most expedient time possible and without unreasonable delay
- Attorney general threshold
- More than 500 Illinois residents (private collectors); 250 for state agencies (Within 45 days of discovery or at the time of consumer notice, whichever is sooner)
- Private right of action
- No: No direct PROA under PIPA; claims may run through the Consumer Fraud Act, and BIPA covers biometric data separately
- Penalty
- Up to $50,000 per violation under the Consumer Fraud Act; restitution prioritized over penalties
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.
