Questions

How many health vendor data breaches were listed in the last 12 months?

116 notices from 87 organizations, listed from Nov 1, 2025 to Oct 25, 2026 by the California, Washington and Texas attorneys general and HHS. Only breaches above each list's filing threshold appear.

What data do health vendor breach notices list most often?

On the Texas and Washington notices that itemize it: Social Security number, name, health insurance ID. California's list doesn't say what was taken; the letter does.

I got a letter from a health vendor. What should I do first?

Check the company above, then check your free credit reports; read your explanation of benefits; freeze your credit at all three bureaus. Your letter is the proof of what was taken and lists any free monitoring offer and its deadline.

Industry comes from the regulator's category when it gives one; otherwise it is guessed from the organization's name. Sources: California, Washington and Texas attorneys general and the HHS Office for Civil Rights, as listed on Oct 25, 2026.
