Shields Health Care Group, Inc. (“Shields”) is providing notice of a data security event that may have involved individuals’ information. Shields provides management and imaging services on behalf of the health care facilities (“Facility Partners”) listed below. With the assistance of third-party forensic specialists, Shields took immediate steps to contain the incident and to investigate the nature and scope of the incident. Shields is issuing this notice on behalf of itself and the Facility Partners to communicate information about the incident, our response, and steps impacted individuals can take, if deemed appropriate.

What Happened? On March 28, 2022, Shields was alerted to suspicious activity that may have involved data compromise. Shields immediately launched an investigation into this issue and worked with subject matter specialists to determine the full nature and scope of the event.

This investigation determined that an unknown actor gained access to certain Shields systems from March 7, 2022 to March 21, 2022. Furthermore, the investigation revealed that certain data was acquired by the unknown actor within that time frame.

Shields worked with specialists to perform a comprehensive review of the potentially affected data to determine what individual personal information may have been involved, and began notifying individuals and regulators last year. Shields continued to review the potentially impacted information and recently completed this review.  Additional notices were mailed beginning April 19, 2023.

What Information Was Involved? The type of information that was or may have been impacted could include one or more of the following: full name, Social Security number, driver’s license number, date of birth, home address, provider information, diagnosis, billing information, insurance number and information, medical record number, patient ID, and other medical or treatment information.

What Are We Doing? Shields takes the confidentiality, privacy, and security of information in our care seriously. Upon discovery, we took steps to secure our systems, including rebuilding certain systems, and conducted a thorough investigation to confirm the nature and scope of the activity and to determine who may be affected. Additionally, while we have safeguards in place to protect data in our care, we continue to review and further enhance these protections as part of our ongoing commitment to data security.

We have notified federal law enforcement, and reported this incident to relevant state and federal regulators. Further, we directly notified impacted individuals where possible so that they may take further steps to help protect their information, should they feel it is appropriate to do so.

What Can Affected Individuals Do? We encourage impacted individuals to review Steps You Can Take to Help Protect Your Information, which is included below.

Steps You Can Take to Help Protect Your Information

Monitor Your Accounts

Under U.S. law, a consumer is entitled to one free credit report annually from each of the three major credit reporting bureaus, Equifax, Experian, and TransUnion. To order your free credit report, visit or call, toll-free, 1-877-322-8228. You may also directly contact the three major credit reporting bureaus listed below to request a free copy of your credit report.

Consumers have the right to place an initial or extended “fraud alert” on a credit file at no cost. An initial fraud alert is a 1-year alert that is placed on a consumer’s credit file. Upon seeing a fraud alert display on a consumer’s credit file, a business is required to take steps to verify the consumer’s identity before extending new credit. If you are a victim of identity theft, you are entitled to an extended fraud alert, which is a fraud alert lasting seven years. Should you wish to place a fraud alert, please contact any one of the three major credit reporting bureaus listed below.

As an alternative to a fraud alert, consumers have the right to place a “credit freeze” on a credit report, which will prohibit a credit bureau from releasing information in the credit report without the consumer’s express authorization. The credit freeze is designed to prevent credit, loans, and services from being approved in your name without your consent. However, you should be aware that using a credit freeze to take control over who gets access to the personal and financial information in your credit report may delay, interfere with, or prohibit the timely approval of any subsequent request or application you make regarding a new loan, credit, mortgage, or any other account involving the extension of credit. Pursuant to federal law, you cannot be charged to place or lift a credit/security freeze on your credit report. To request a security freeze, you may need to provide the following information, depending on whether you make the request online, by phone, or by mail:

  1. Full name (including middle initial as well as Jr., Sr., II, III, etc.);
  2. Social Security number;
  3. Date of birth;
  4. Addresses for the prior two to five years;
  5. Proof of current address, such as a current utility bill or telephone bill;
  6. Social Security Card, pay stub, or W2;
  7. A legible photocopy of a government-issued identification card (state driver’s license or ID card, etc.); and
  8. A copy of either the police report, investigative report, or complaint to a law enforcement agency concerning identity theft if you are a victim of identity theft.
