Delta Dental of Washington provides insurance coverage to a large portion of the state’s population. Any breach involving internal files at such an organization typically includes documents that contain names, addresses, dates of birth, Social Security numbers, policy details, and medical claims information.
Why This Matters for You and Your Family
When a health insurer’s internal files are stolen, the consequences reach far beyond the company. Dental insurance records often link directly to your full name, address, phone number, email, date of birth, and policy numbers. In many cases they also contain Social Security numbers used for verification or tax purposes. Once that information leaves secure systems, it can be sold, traded, or used to file fraudulent claims, open accounts in your name, or strengthen identity theft attempts against you or your children.
