Hi,
I bill for PA's as assistant surgeons and I use the Modifier AS, Not 80... And some claims do get paid and some do not. I do not have a sample letter for as each case is different.
Using the Fee Schedule on Trailblazerhealth.com there is determination area for the need of assistant surgeons.
A lot of appeals are done fighting for their payment, even with the documentation some payers will not pay.Best of luck.
Have a Super Weekend!
