Section F.2 / In context

Where this filing sits in Missouri 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 100 of the 164 Missouri filings (61%) and on 21% of all filings submitted in 2015. Network Server appears on 38% of Missouri filings.

No business associate is recorded on the filing; 23% of Missouri filings do involve one. At 12,500 individuals the breach is 2.6 times the Missouri median filing of 4,800 and 3.1 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.

Missouri's breach notification statute (Mo. Rev. Stat. 407.1500) requires notice to affected residents without unreasonable delay. Its attorney general threshold: more than 1,000 Missouri consumers. 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 12,500 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 $2.00M; the 2026 edition's $192 gives $2.40M. Both are modelled estimates with the method shown, not costs disclosed by Concordia Plan Services on behalf of the Concordia Health Plan. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.4 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 Concordia Plan Services on behalf of the Concordia 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 12,500 individuals who received health insurance from the CE. The ePHI involved 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.

Section F.5 / Modelled cost

Modelled cost / method shown, not a disclosed cost

Modelled

IBM 2025 customer PII, $160 per record

$2.00M

12,500 x $160

IBM 2026 customer PII, $192 per record

$2.40M

12,500 x $192

Method: individuals affected, as reported by Concordia Plan Services on behalf of the Concordia 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.
