Section F.2 / In context

Where this filing sits in Michigan and in 2023

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 148 of the 238 Michigan filings (62%) and on 82% of all filings submitted in 2023. Network Server appears on 45% of Michigan filings.

No business associate is recorded on the filing; 30% of Michigan filings do involve one. At 15,298 individuals the breach is 4.1 times the Michigan median filing of 3,754 and 3.8 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.

Michigan's breach notification statute (MCL 445.72) requires notice to affected residents without unreasonable delay. Its attorney general threshold: not currently required (pending SB 360 would require it at 100+ 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 15,298 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 $2.45M; the 2026 edition's $192 gives $2.94M. Both are modelled estimates with the method shown, not costs disclosed by Northeast Surgical Group, PC. 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 Northeast Surgical Group, P.C. (NESG), a provider of surgical services in Michigan, for a potential violation under the Health Insurance Portability and Accountability Act of 1996 (HIPAA) Security Rule. 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 (PHI). The HIPAA Security Rule establishes national standards to protect and secure our health care system by requiring administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and security of electronic PHI. The settlement resolves an investigation concerning a ransomware attack on NESG's information system.

"One of the first steps in implementing effective cybersecurity in health care is assessing the potential risks and vulnerabilities to electronic protected health information," said OCR Director Melanie Fontes Rainer. "A failure to conduct a HIPAA risk analysis will leave a health care entity vulnerable to cyberattacks, such as hacking and ransomware-which is bad for our health care system and bad for patients. We can and must do better."

Ransomware and hacking are the primary cyberthreats in health care. Ransomware is a type of malware (malicious software) designed to deny access to a user's data, usually by encrypting the data with a key known only to the hacker who deployed the malware, until a ransom is paid. Since 2018, there has been a 264% increase in large breaches reported to OCR involving ransomware attacks. The settlement also marks the fourth 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 ePHI; to increase the number of completed investigations; and to highlight the need for more attention and better compliance with this Security Rule requirement.

In March 2023, OCR received a breach report concerning a ransomware incident that had affected NESG's information system. NESG concluded that the protected health information of 15,298 patients had been encrypted and exfiltrated from its network. OCR's investigation determined that NESG had failed to conduct a compliant risk analysis to determine the potential risks and vulnerabilities to ePHI in NESG's systems.

Under the terms of the resolution agreement, NESG agreed to implement a corrective action plan that OCR will monitor for two years and paid $10,000 to OCR. Under the corrective action plan, NESG will take 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

15,298 individuals through IBM's per-record figures

Modelled cost / method shown, not a disclosed cost

Modelled

IBM 2025 customer PII, $160 per record

$2.45M

15,298 x $160

IBM 2026 customer PII, $192 per record

$2.94M

15,298 x $192

Method: individuals affected, as reported by Northeast Surgical Group, PC 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.
