Looks like a phishing call. Called themselve "Swedish Medical Billing." Immediately asked for personal information... unverifyable number. I'd call Swedish directly.
If they want me to pay my bill, they shouldn't ask questions that they should know the answers to & act as though they are HIPAA related. I know HIPAA & they are hiding behind it...
Call from Swedish Medical Billing. They want to clear up their previous year accounts. Informed me that, if I payed it off by December 1st this year, they'd cut my bill by 45%. It is a good deal for me!
