不用理他们。 诊所胡搅蛮缠。可能刚开业， 不懂什么叫contract.

any in-network Dr. can only get contracted price no matter how much he/she bills.

They can charge whatever amount they want, actually not, they have to disclose the charge master they use (some kind of billing software), but only get reimbursed at contracted fee schedule amount.
