Hi,

In my expereince, modifier -59 should always be listed in the last position. Modifiers that affect payment (adjustment to fee schedule amount) such as -26/-TC, -80, -62, -50... should be listed 1st and "informational" modifiers should be listed after these. Though -59 does affect payment in the sense that if you don't use it, the claim will deny, but it is not one the affects the fee schedule amount. Make sense?

As far as your second question, I do not know the answer to that. Sorry...

Hope that helps,
:) Erica
