I´ve posted here about an ER visit in the US back in February. The bill, for a mere ultrasound that took 10 minutes, came to nearly $3,000 USD. My Argentine insurer paid all but a $200 bill which was mistakenly sent to my mother´s address in the US. At least the hospital SAID that they sent the $200 bill to her address. Recently I returned for a short visit to the US and by coincidence I was there when a collection agency bill came for the $200. Maybe the original bill went astray. Who knows? The Argentine health insurer agree to pay the bill but they insist on an itemization. The US collection agency will NOT cooperate. They say that they will send a fax of the bill but they don´t do it. They are rude and aggrssive on the phone. I have called numerous times but I get nowhere. Seems they want me to pay with a credit card and ask the Argentine insurar for reimbursement. I refuse. I really don´t know how to handle this. To be honest, their attitude and dishonest behavior is worse than I have encountered in Argentina. ANY SUGGESTIONS?
