PsychPlus Data Breach Exposes Sensitive Patient Information of Over 4,500 Texas Residents Psychiatry of Texas PLLC (operating as PsychPlus), a Houston-based psychiatric practice, disclosed a data breach affecting at least 4,565 Texas residents after detecting unauthorized access to its systems on March 31, 2026. The incident, confirmed through an internal investigation with cybersecurity specialists, involved the exposure of protected health information (PHI) belonging to patients including those treated by affiliated healthcare providers. The compromised data varied by individual but potentially included names, Social Security numbers, dates of birth, medical diagnoses, health insurance details, account numbers, usernames, email addresses, passwords, and parental premarital surnames. PsychPlus first reported the breach to the Texas Attorney General on September 1, 2026, and began notifying affected individuals on August 27, 2026, via a public press release. In response, the company is offering complimentary credit monitoring and identity protection services through HaystackID and has established a dedicated assistance line (855-205-9558) for impacted individuals. The breach underscores the growing risks to sensitive healthcare data in the psychiatric and broader medical sectors.
