Section F.2 / In context
Where this filing sits in Arizona and in 2025
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 94 of the 164 Arizona filings (57%) and on 81% of all filings submitted in 2025. Network Server appears on 43% of Arizona filings.
A business associate is recorded as present on the filing, as it is on 21% of Arizona filings. At 10,673 individuals the breach is 3.4 times the Arizona median filing of 3,146 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. The archive entry carries no closing summary.
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 10,673 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 $1.71M; the 2026 edition's $192 gives $2.05M. Both are modelled estimates with the method shown, not costs disclosed by U.S. HEALTHWORKS-SMMPP, L.C.. 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.

Method: individuals affected, as reported by U.S. HEALTHWORKS-SMMPP, L.C. 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.
