Section F.2 / In context

Where this filing sits in Arkansas and in 2016

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 50 of the 92 Arkansas filings (54%) and on 35% of all filings submitted in 2016. Network Server appears on 49% of Arkansas filings.

No business associate is recorded on the filing; 28% of Arkansas filings do involve one. At 16,200 individuals the breach is 3.4 times the Arkansas median filing of 4,800 and 4.0 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.

Arkansas's breach notification statute (Ark. Code Ann. 4-110-101 et seq.) requires notice to affected residents in the most expedient time and manner possible and without unreasonable delay. Its attorney general threshold: more than 1,000 Arkansas residents. 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 16,200 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 $2.59M; the 2026 edition's $192 gives $3.11M. Both are modelled estimates with the method shown, not costs disclosed by ENT and Allergy Center. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.5 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.

One or more hackers attacked the data servers of Bizmatics, a business associate (BA) for the covered entity (CE), ENT & Allergy Center, which resulted in unauthorized access to Bizmatics' customer records including those of the CE. Approximately 16,200 patient's electronic medical records were compromised. The types of protected health information involved in the breach included demographic and clinical information. OCR opened an investigation of the CE to determine if the CE complied with the HIPAA Privacy and Security Rules with respect to business associate contracts. OCR reviewed the business associate agreement between the CE and BA and determined that it appears to be consistent with the requirements of the Privacy and Security Rules. OCR initiated a separate investigation of Bizmatics.

Section F.5 / Modelled cost

Modelled cost / method shown, not a disclosed cost

$2.59M

16,200 x $160

IBM 2026 customer PII, $192 per record

$3.11M

16,200 x $192

Method: individuals affected, as reported by ENT and Allergy Center 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.
