I got a letter from a health plan. What should I do first?
Check the company above, then read your explanation of benefits; check your free credit reports. 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.
