We take assignment on some Medicare orders, depending on the products. (Please inquire if you need to know for certain prior to submitting your order.) We do take assignment on BlueCross BlueShield orders, but in many cases there is a CO-PAY due. Until we know if you have a CO-PAY and what the percentage is, we automatically charge a 20% CO-PAY. If your CO-PAY is less than 20% you will receive a check from us from St. Louis Medical Supply for the difference. If your CO-PAY is more, you will receive a bill. If you have anymore insurance related questions feel free to email our insurance billing department.
