Insurance carriers won't (not supposed to) tell you how much a patient has to go to satisfy the deductible, they can only tell you the deductible amount and yes or no it's been satisfied.
I never knew this, because whether I verify insurance through a website, or by speaking to a person at the insurance company, they always tell me(even when I don't ask) how much of the deductible has been met for the year, down to the penny.
