Section F.2 / In context

Where this filing sits in Oklahoma and in 2022

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 58 of the 80 Oklahoma filings (73%) and on 79% of all filings submitted in 2022. Network Server is the most common location in the state, appearing on 51% of Oklahoma filings.

No business associate is recorded on the filing; 33% of Oklahoma filings do involve one. At 14,273 individuals the breach is 3.7 times the Oklahoma median filing of 3,849 and 3.6 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.

Oklahoma's breach notification statute (Okla. Stat. tit. 24, 161 et seq.) requires notice to affected residents without unreasonable delay. Its attorney general threshold: 500 or more Oklahoma 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 14,273 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 $2.28M; the 2026 edition's $192 gives $2.74M. Both are modelled estimates with the method shown, not costs disclosed by Bryan County Ambulance Authority. 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.

Today, the U.S. Department of Health and Human Services (HHS), Office for Civil Rights (OCR) announced a settlement with Bryan County Ambulance Authority (BCAA), a provider of emergency medical services in Oklahoma for a potential violation of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Security Rule. The settlement resolves an investigation concerning a ransomware attack on BCAA's information systems. Ransomware and hacking are the primary cyberthreats in health care. Since 2018, there has been a 264% increase in large breaches reported to OCR involving ransomware attacks. The settlement also marks the first enforcement action in OCR's Risk Analysis Initiative. This enforcement initiative was created to focus select investigations on compliance with the HIPAA Security Rule Risk Analysis provision, a key Security Rule requirement, and the foundation for effective cybersecurity and the protection of electronic protected health information (ePHI).

OCR enforces the HIPAA Privacy, Security, and Breach Notification Rules, which set forth the requirements that covered entities (health plans, health care clearinghouses, and most health care providers) and business associates must follow to protect the privacy and security of protected health information. The HIPAA Security Rule establishes national standards to protect individuals' ePHI that is created, received, used, or maintained by a covered entity or business associate. It also requires appropriate administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and security of ePHI. The settlement resolves OCR's investigation concerning BCAA and this ransomware attack.

In May 2022, OCR received a breach report concerning a ransomware incident that encrypted files on BCAA's network. BCAA determined that the encrypted files affected the protected health information of 14,273 patients. OCR's investigation determined that BCAA had failed to conduct a compliant risk analysis to determine the potential risks and vulnerabilities to ePHI in BCAA's systems.

Under the terms of the resolution agreement, BCAA agreed to pay $90,000 and to implement a corrective action plan that will be monitored by OCR for three years. Under the corrective action plan, BCAA will take a number of steps to ensure compliance with the HIPAA Security Rule and protect the security of ePHI, including:

Conducting an accurate and thorough risk analysis to determine the potential risks and vulnerabilities to the confidentiality, integrity, and availability of its ePHI;

Implementing a risk management plan to address and mitigate security risks and vulnerabilities identified in their risk analysis;

Developing, maintaining, and revising, as necessary, its written policies and procedures to comply with the HIPAA Rules; and

Training its workforce on its HIPAA policies and procedures.

Section F.5 / Modelled cost

14,273 individuals through IBM's per-record figures

Modelled cost / method shown, not a disclosed cost

Modelled

IBM 2025 customer PII, $160 per record

$2.28M

14,273 x $160

IBM 2026 customer PII, $192 per record

$2.74M

14,273 x $192

Method: individuals affected, as reported by Bryan County Ambulance Authority 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.
