Section F.2 / In context
Where this filing sits in Indiana and in 2023
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 119 of the 200 Indiana filings (60%) and on 82% of all filings submitted in 2023. Network Server appears on 42% of Indiana filings.
No business associate is recorded on the filing; 31% of Indiana filings do involve one. At 154,285 individuals the breach is 43 times the Indiana median filing of 3,600 and 39 times the national median of 4,000 across all 7,884 filings. It is one of 801 filings of 100,000 or more individuals.
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.
Indiana's breach notification statute (Ind. Code 24-4.9) requires notice to affected residents without unreasonable delay, no more than 45 days after discovery. Its attorney general threshold: all qualifying breaches. 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 154,285 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 $24.7M; the 2026 edition's $192 gives $29.6M. Both are modelled estimates with the method shown, not costs disclosed by Cummins Behavioral Health Systems. 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.
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), Cummins Behavioral Health Systems, reported that it experienced a ransomware attack the affected the protected health information (PHI) of 154,285 individuals. The PHI involved included names, addresses, dates of birth, Social Security numbers, diagnoses/conditions, medications, and other treatment information. In response to the breach, the CE implemented additional administrative and technical safeguards. OCR provided the CE with technical assistance.

Method: individuals affected, as reported by Cummins Behavioral Health Systems 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.
