<prompt> Human: Since Blue Cross had the hack two years ago I have not given SSN to insurance. Do I need to? The letter I received from Anthem says its for the IRS to match people as part of ACA and that The IRS may impose penalties to individuals who have not provided... this info.If I received a penalty from the IRS, couldnt I respond TO THE IRS with my insuance documentation to avoid the penalty? I just cant see the value to me giving it to the insurance company over the risk of them having it and misusing it.Is my tinfoil hat just too tight?  <response>: How are you even able to obtain insurance for your kids without providing their SSNs?
