Section F.2 / In context
Where this filing sits in Nevada and in 2024
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 31 of the 55 Nevada filings (56%) and on 83% of all filings submitted in 2024. Network Server is the most common location in the state, appearing on 55% of Nevada filings.
No business associate is recorded on the filing; 25% of Nevada filings do involve one. At 11,321 individuals the breach is 2.9 times the Nevada median filing of 3,898 and 2.8 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.
Nevada's breach notification statute (Nev. Rev. Stat. 603A.010 et seq.) requires notice to affected residents in the most expedient time possible and without unreasonable delay. Its attorney general threshold: no AG notification requirement. 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 11,321 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 $1.81M; the 2026 edition's $192 gives $2.17M. Both are modelled estimates with the method shown, not costs disclosed by Somerset Dental. 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.
The covered entity (CE), Somerset Dental, reported that it was the subject of a cyber-attack that affected the protected health information (PHI) of 11,321 individuals. The PHI involved included names, dates of birth, addresses, drivers' license and Social Security numbers, diagnoses, and claims and other treatment information. The CE notified HHS, affected individuals, the media, and provided substitute notice. In response to the breach, the CE provided complimentary credit monitoring services and implemented additional administrative, technical, and security safeguards.

Method: individuals affected, as reported by Somerset Dental 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.
