Can someone be charged a yearly deductible twice? Or be charged more than what your yearly deductible is supposed to be? My father's yearly deductible is $147, he saw the gastroenterologist on 1/29/13 and was charged that deductible when to went to the doc's office. He had to pay that full amount upfront. Okay that's fine since I know he is supposed to pay that every year before medicare helps pay the 80%, but what has me confused is that he saw his primary doctor first on 1/10/13, and when I look up his medicare claims it shows that medicare had already applied $115.84 towards his deductible(although my father wasn't charged that by his primary doc when he went to the office). Then my father had a procedure done on 1/14/13 with an anesthesiologist and it shows on his medicare claims page that $31.16 was applied towards his deductible (my father hasn't been billed that yet either) So how is it that he saw two doctors first before the gastroenterologist, but none of the two charged a deductible first? Yet the third doctor was fast to charge the deductible? Also why does the medicare claims page show that he was applied a deductible from the first two docs yet he hasn't payed anything when he has stepped foot in their offices? What happens if the two first doctors decided to charge him what was applied towards his deductible? Does he have to pay another deductible? I mean he already payed the 3rd doctor the full deductible amount of $147. I have attached a word file below so that you can hopefully get a clearer picture of what I am talking about. Someone please help, I am so confused about this, thank you a bunch!
