Change health care

I received a letter from Change Health care stating that on Feb 21 2024, CHC found activity in OUR computer system that happened w/o our permission, on feb 17 2024 and feb 20 2024.
Since I am insured in a state system, why did they not tell me?
They sent a link for you to sign up with a monitoring service, under qqq.changecybersupport.com, and i am very suspicious.

I believe that after the Change hack the agreement was that Change would do the notifications and provide the credit monitoring. Otherwise, given the number of client businesses affected, you would likely have received notifications from multiple companies.

is someone sharing my health info with a company called change? If a place called Change was hacked what was my united health plan doing at a place called change?

They are a payment processing company that handles billing and health insurance for a lot of healthcare entities. Similar to a pharmacy benefits manager for medical.

so your data can be compromised anywhere along a chain of handlers?

Pretty much so since they are an intermediary. This particular event occurred early this year. The company took their systems offline when it was discovered. You may remember when many pharmacies were having difficulty trying to fill prescriptions for a few weeks while they couldn’t communicate with the insurers. Medical offices also had issues.
