About Nabi Health, Inc.
Nabi Health, Inc. is a fully virtual outpatient nutrition therapy practice based in San Francisco, California. Founded in 2023, the company employs a team of Registered Dietitians who specialize in eating disorder treatment and recovery, and also treat disordered eating, digestive health concerns, hormonal conditions, and chronic disease. Nabi Health serves patients ages six and older across most U.S. states and accepts major insurance plans. Because the company collects patient intake information through its website portal, even limited intake data can be sensitive for individuals seeking treatment for eating disorders or related conditions.
What Happened?
Nabi Health, Inc. was listed in an HHS Office for Civil Rights breach portal report submitted on October 6th, 2026. The incident was classified as an unauthorized access/disclosure affecting information stored on a network server and another location. A total of 783 individuals were affected.
On August 10th, 2026, Nabi Health discovered that a former vendor had maintained access to certain personal information after the vendor relationship ended. The exposed data was limited to patient intake information entered through the company’s website portal — specifically, individual names and stated reasons for visit. Nabi Health confirmed that patient medical records, Social Security numbers, and financial account information were not involved. The company completed its review and finalized the list of individuals to notify on September 24th, 2026, and filed a breach notification letter with Massachusetts regulators in October 2026. Notification letters were mailed through a return processing center operated by HaystackID, which also provided fraud assistance and credit monitoring services to affected individuals.
No class action lawsuit has been filed as of the research date, though Class Action U has published an investigatory page about the breach. No prior HHS breach filings were found for Nabi Health.

What Should You Do?
If you received a notice from Nabi Health, enroll in the credit monitoring and fraud assistance services offered through HaystackID before any enrollment deadline stated in your letter. Even though medical records and financial account information were not involved, the exposed data — your name and stated reason for visiting the Nabi Health portal — could be misused. Consider placing a fraud alert or credit freeze with the three major credit bureaus (Equifax, Experian, and TransUnion), and monitor your credit reports for unfamiliar accounts or activity. You can request free annual credit reports at AnnualCreditReport.com. If you suspect your information has been misused, visit IdentityTheft.gov for step-by-step guidance on responding to identity theft. Because this incident involved information connected to healthcare treatment, also review any Explanation of Benefits statements from your insurer and check that your medical records accurately reflect only the care you have actually received.
