Please be advised that a billing mistake was made in processing payment for the enclosed bill from my physician, . You have paid him as an out-of-network provider, but he is a member of the network of physicians in my plan. He practices with the medical group at the address on the enclosed bill.
Please review the payment of this claim. I should not have any liability for payment, except for the $ co-payment I already made. You should have paid at % reimbursement instead of the % rate.
Thank you for your prompt attention to this matter.
Very truly yours,
[First Name][Last Name]
