I'm having an issue with a local Medicare carrier, and I'm looking for some documentation, one way or the other.
We have some claims that keep denying for an FNP, who's performing burn debridements on her own. We're billing 16030, with no modifiers, under the FNP's own provider numbers. We keep getting denied by one particular insurer (on Medicare Advantage plan), saying that a modifier is required because the performing provider is not an MD.
They want an AS modifier. I have explained that my understanding of the AS modifier, is that it's for use:
1. When the provider is assisting at surgery, and not performing services independently, and
2. When the services are being billed under the supervising physician on behalf of the NPP.
The response I got from their auditor, was that we need to add the AS modifier so that they can tell that the provider is not an MD (despite the fact that we're billing with FNP provider type 50, and she's credentialed as an FNP), and that if she performed the services independently, and not as an assistant at surgery, we'd have to submit records to prove it.
Has anyone else ever run into this? I didn't think that it would be assumed that the provider was an assistant at surgery, just because they weren't an MD (and that I'd have to prove otherwise), and I've never had any other payor tell me that we need to append an AS modifier, simply to show that the provider's not an MD, when we're not billing under an MD's credentials. I've asked them to show me where they're getting their info, but they've kind of been dodging my questions. The only info I can find that supports my explanation of using the AS modifier on claims billed under the supervising MD, is actually on BCBS's website, which does me no good, here. Does anyone know of a CMS/MAC policy that spells this out in black and white?
Any help is much appreciated, even if it turns out I'm wrong on this.
