Bilateral Procedure Question

I have a quick question..... I have been billing my bilateral procedure codes (I'm in a ASC, so many different codes) as one line item with a LT and RT modifier - with the understanding that the insurance should pay at 150%.

I'm now being told by another employee (who is not a coder) that this is wrong and I have to bill 2 line items for all bilateral procedures and calculate for double payment.

Can anyone shed some light on this for me?

Thanks

Angie
