In May 2023, healthcare providers reported 36 breaches, business associates reported 25 breaches and health plans reported 14; nonetheless, those numbers do not exactly indicate where the data breaches happened.

Arizona, Arkansas, Kentucky, Kansas, Georgia, Michigan, Minnesota, New Mexico, New Hampshire, Oklahoma, South Dakota, Utah, Tennessee, Virginia, Washington, Wisconsin and West Virginia reported one each.

HIPAA Enforcement Activity in May 2023

After two months without HIPAA enforcement actions, May had many enforcement activities in May associated with HIPAA compliance failures. OCR issued two financial penalties to settle HIPAA violations. State attorneys general announced two enforcement actions, and the Federal Trade Commission (FTC) reported one enforcement action involving a non-HIPAA-regulated entity for impermissibly disclosing consumer health data.

In May, OCR issued its 44th financial penalty in relation to its HIPAA Right of Access enforcement initiative. Counselor David Mente, MA, LPC in Pittsburgh was to pay $15,000 for not giving a father the health records of his young children, in spite of the father submitting two requests to get a copy of the records and OCR giving technical support after getting the first complaint.

The New York Attorney General consented to a settlement agreement to resolve HIPAA violations and state legislation violations that were confirmed in the course of an investigation of Professional Business Systems Inc, also known as PBS Medcode Corp, and Practicefirst Medical Management Solutions. The healthcare management firm was investigated after submitting a ransomware attack and data breach report involving 1.2 million people. The hackers acquired access to its system by taking advantage of a vulnerability that hadn’t been patched, even though there is a patch since 22 months ago. Practicefirst’s HIPAA and state regulations violations are due to failures in patch management, security testing inabilities, and not using encryption. The case was resolved for $550,000.
