Section F.2 / In context
Where this filing sits in Arizona and in 2020
OCR classifies the incident as a hacking or IT incident, with the breached information held in email and a network server. Hacking/IT Incident is the type recorded on 94 of the 164 Arizona filings (57%) and on 69% of all filings submitted in 2020. Email appears on 26% of Arizona filings.
A business associate is recorded as present on the filing, as it is on 21% of Arizona filings. At 314,704 individuals the breach is 100 times the Arizona median filing of 3,146 and 79 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.
Arizona's breach notification statute (A.R.S. 18-551, 18-552) requires notice to affected residents within 45 days after determining a breach occurred. Its attorney general threshold: more than 1,000 Arizona residents (AG and Dept. of Homeland Security). 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 314,704 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 $50.4M; the 2026 edition's $192 gives $60.4M. Both are modelled estimates with the method shown, not costs disclosed by Magellan Rx Management. 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.
Magellan Rx Management, the covered entity (CE), reported that its business associate (BA) experienced a ransomware attack. This case is duplicative of an investigation being conducted into the BA that affected multiple CEs. Therefore, this case is closed and consolidated into an existing investigation.

Method: individuals affected, as reported by Magellan Rx Management 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
Arizona statute and the HIPAA rule
State notification statute
Arizona: A.R.S. 18-551, 18-552
- Notice to individuals
- Within 45 days after determining a breach occurred
- Attorney general threshold
- More than 1,000 Arizona residents (AG and Dept. of Homeland Security) (Within the same 45-day window)
- Private right of action
- No: Only the Arizona Attorney General may enforce
- Penalty
- Up to $10,000 per affected individual, capped at $500,000 per breach, under the Consumer Fraud Act
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.
