Section F.2 / In context
Where this filing sits in Minnesota 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 114 of the 189 Minnesota filings (60%) and on 21% of all filings submitted in 2015. Network Server appears on 43% of Minnesota filings.
A business associate is recorded as present on the filing, as it is on 35% of Minnesota filings. At 10,946 individuals the breach is 3.5 times the Minnesota median filing of 3,159 and 2.7 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.
Minnesota's breach notification statute (Minn. Stat. 325E.61) requires notice to affected residents in the most expedient time possible and without unreasonable delay. Its attorney general threshold: no general AG requirement (reporting agencies at 500+ residents within 48 hours). 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 10,946 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 $1.75M; the 2026 edition's $192 gives $2.10M. Both are modelled estimates with the method shown, not costs disclosed by SUPERVALU Group Health Plan. 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.
Blue Cross and Blue Shield of Minnesota, a business associate (BA) of Supervalu Group Health Plan, the covered entity (CE), stored the CE's electronic protected health information (ePHI) on computer servers belonging to its parent corporation, Anthem, Inc. Anthem experienced a series of cyberattacks which exposed the electronic protected health information (ePHI) of almost 79 million people, affecting 10,946 individuals who received health insurance from the CE. The ePHI involved in the breach included names, social security numbers, medical identification numbers, addresses, dates of birth, email addresses, and employment information. OCR reviewed the BA agreement and determined that it appeared to comply with the requirements of the HIPAA Privacy and Security Rules. OCR opened a separate review of Anthem, which resulted in Anthem agreeing to pay a monetary settlement and undertaking a robust corrective action plan to comply with the HIPAA Rules.

Method: individuals affected, as reported by SUPERVALU Group Health Plan 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.
