On July 23, 2026, the HIPAA Journal reported on a data breach at Unlimited Technology Systems, a Montgomery, Ohio-based provider of revenue cycle management services. At the time, the scale of the data breach had yet to be made public, but it has recently been confirmed to be the largest healthcare data breach of the year to date, ahead of the 3.4 million-record data breach at Trizetto Provider Solutions.

According to the breach summary on the HHS’ Office for Civil Rights data breach portal, the Unlimited Technology Systems data breach involved the protected health information of 3,803,750 individuals. While the incident was confirmed in July, it was first identified in October 2025. The threat actor had access to its network between October 5 and October 10, 2025, and potentially exfiltrated files containing patient data (as detailed below). No threat group appears to have claimed responsibility for the cyberattack.

Business associates of healthcare organizations are attractive targets for cybercriminals. If their systems are compromised, hackers can gain access to highly sensitive patient data from many different healthcare companies. Six of the top ten data breaches reported this year occurred at business associates, as did 50% of the largest healthcare data breaches of all time. The proposed update to the HIPAA Security Rule includes several measures to tighten security at business associates and strengthen vendor oversight by HIPAA-covered entities. While planned for a mid-2026 release, the final rule has been delayed, with OCR now expecting to release the final rule by July 2027.

July 23, 2026: Patient Data Exposed in Cybersecurity Incident at Ohio Revenue Cycle Management Company

Unlimited Technology Systems LLC (UTS), a Montgomery, Ohio-based revenue cycle management company and practice management software provider, has identified unauthorized activity within a commercial data center that contained the personal and protected health information of patients of its healthcare provider clients.

According to its data breach notification letter, unauthorized activity was identified on October 19, 2025. Assisted by a third-party cybersecurity and digital forensics company, UTS determined that an unauthorized third party may have obtained a copy of files from that environment between October 5 and October 10, 2025.

The data review has recently been completed, and UTS has confirmed that the following types of information may have been involved: name, address, email address, phone number, date of birth, health insurance information, patient balance information, Social Security number, medical information including diagnosis, and scanned documents such as driver’s license or other government ID documents. UTS said full medical records, medical images, and financial information were not involved.

As a precaution against data misuse, the affected individuals have been offered complementary credit monitoring services for 24 months, and UTS has implemented enhanced security measures to prevent similar incidents in the future.  The incident is not yet shown on the HHS’ Office for Civil Rights breach portal, so it is unclear how many individuals have been affected.

According to the OCR breach report, the protected health information of 11,848 individuals was potentially compromised in the incident.

The security incident was first identified on April 16, 2026. The forensic investigation confirmed that an unauthorized third party gained limited access to parts of its network and downloaded files containing protected health information. Data compromised in the incident includes names, Department of Defense Benefits Numbers, beneficiaries’ ZIP codes, and health-related information. Only 5 individuals had their addresses, dates of birth, and Social Security numbers stolen.

At the time of issuing notification letters, some of which were sent on July 2, 2026, no misuse of the impacted information had been identified; however, as a precaution against data misuse, the affected individuals have been offered complimentary credit monitoring services for 24 months. Security controls have been enhanced, system monitoring tools have been strengthened, and additional security awareness training has been provided to its workforce.

Texas Medicaid and Healthcare Partnership

Texas Medicaid and Healthcare Partnership (TMHP), a state Medicaid contractor, has recently reported a data breach to the HHS’ Office for Civil Rights involving the protected health information of 2,045 individuals.  According to the TMHP substitute data breach notice, this was a fraud-related incident that involved unauthorized access to certain internal systems between February 5, 2026, and March 26, 2026.

When the unauthorized access was detected, immediate action was taken to contain the incident and secure its network, and additional security measures have been implemented to harden security. The forensic investigation determined on April 20, 2026, that personal and protected health information of 1,828 Medicaid clients and 217 healthcare providers had been exposed.

For Medicaid clients, the data compromised in the incident included full names, addresses, dates of birth, Social Security numbers, Medicaid numbers, Medicaid benefits information, Medicaid card information, and health information. Healthcare provider information included full names, addresses, emails, medical license information, financial information, driver’s license numbers, Social Security numbers, tax identification numbers, and other provider enrollment management system information.

Notification letters were mailed to the affected individuals on June 18, 2026, who have been offered complimentary identity theft protection and identity recovery services. TMHP said that at the time of issuing notifications, no information had been found to indicate any actual or attempted misuse of the impacted information.

Minnesota Health Insurance Network

Minnesota Health Insurance Network, a Burnsville, MN-based health insurance brokerage, has started notifying individuals about a recent security incident that exposed personal and protected health information. The security incident was identified on March 17, 2026, and its forensic investigation determined that there had been unauthorized access to parts of its network between March 16 and March 17, 2026, during which time files were exfiltrated from its network.

The affected data has been reviewed and found to include names, dates of birth, Social Security numbers, driver’s license/state ID numbers, other government-issued ID numbers, financial account numbers, credit/debit card information, diagnosis and treatment information, and health insurance information. Individuals whose Social Security numbers were involved have been offered complimentary credit monitoring services. While regulators have been notified, the incident is not currently listed on the HHS’ Office for Civil Rights website, so it is unclear how many individuals have been affected.

Secure Health Plans of Georgia

Secure Health Plans of Georgia (Secure Health), a provider of administrative services, care management, and healthy lifestyle programs to employers with self-funded health benefit plans, is reviewing files that were exposed in a recent cybersecurity incident. The incident was identified on February 12, 2026, and the forensic investigation confirmed unauthorized access to its systems on or before February 3, 2026, until February 12, 2026. During that time, files containing individuals’ protected health information may have been viewed or copied. Secure Health has not yet confirmed the exact types of information exposed in the incident, although protected health information was exposed.

The incident has been reported to the HHS’ Office for Civil Rights using a placeholder estimate of at least 501 individuals. The total will be updated when the data review is concluded, and notification letters will be mailed stating the types of data involved. Secure Health has taken steps to strengthen security to prevent similar incidents in the future.

Clover Health Investments has notified the U.S. Securities and Exchange Commission (SEC) about a cybersecurity incident first identified on July 4, 2026. Clover Health Investments is a publicly traded health insurer that provides Medicare Advantage plans, directly contracts with the U.S. government, and manages care for Medicare beneficiaries in 11 states. The company also provides technology and software tools to physicians.

Unusual login activity was identified, and its forensic investigation confirmed that a hacker had accessed three employee email accounts after the employees had been tricked by social engineering into disclosing their credentials. Clover Health activated its incident response plan to contain the incident and believes that unauthorized access has been terminated.

Clover Health said the compromised accounts belonged to non-managerial health plan employees who were responsible for handling member visit scheduling and broker-facing sales work. The accounts did not have permissions to access corporate financial or claims systems, but they could access some personal and protected health information.

The volume of exposed data has yet to be determined, and Clover Health has not publicly confirmed whether sensitive data was exfiltrated from its systems. Clover Health has reported the incident to law enforcement and is working with third-party cybersecurity experts to investigate the incident and review the information that was exposed, viewed, or exfiltrated.

Clover Health said it does not believe that the incident has had a material impact on business operations, its financial condition, or results of operations. Notifications will be mailed to the affected individuals if it is determined that HIPAA-protected data has been exposed or stolen, and Clover Health has confirmed that steps are being taken to strengthen security to prevent similar incidents in the future.
