What happened

A ransomware attack on Change Healthcare, the UnitedHealth unit that processes insurance claims and payments for much of the US health system, stole data in February 2024 and disrupted pharmacies and providers for weeks. Stolen files included contact details, Social Security numbers, ID documents, diagnoses, test results, insurance and billing information. The company's count to federal regulators rose to about 192.7 million people, the largest US health data breach on record.

What should I do?

  1. Read every Explanation of Benefits from your health insurer and report any visit, test or prescription you never had.
  2. Freeze your credit for free at Equifax, Experian and TransUnion so no one can open new accounts in your name.
  3. Request an IRS Identity Protection PIN so nobody can file a tax return with your Social Security number.
  4. Sign up for the free credit or identity monitoring offered in the notice letter before its enrollment deadline.
