I'm not sure what you are referring to with a PAS code. The only thing that I can think of that comes close is are Category and Pass through codes.

Im not sure what biller's roles are in APC's but I would think its similar to DRG's- they submit the codes, charges, rev codes, etc and the APC's are recalculated within Medicare's system.

Working with a surgeon, you don't need to worry about APC's as they are for hospital based surgery centers. What the surgeons (and other docs) need to know is to DOCUMENT.

I'll go through an APC basics in a bit.

PS- Don't worry, i did DRG Education for a while, it doesn't hurt to dig in the trenches of my brain to keep this stuff fresh!
