In general, doctors want their co-pays up front. This has been going on for some time now. People wait to be billed and then don't pay their co-pay. Or take months to pay their co-pay. I don't blame doctors one iota for that. Invoicing over and over again over months and months in order to get a patient to pay a $30 bill is inefficient and means that doctors are turning over these unpaid co-pays to collection agencies. This is nothing new.
If you'll notice in the first quote you picked up, the up-front amounts are based on an estimated cost of service. Not that one will have to pay their entire deductible up front.
This is another one of those half-truths being bandied about to scare the livin' bejesus out of people.
