[Histonet] Billing IHC on MOHS

[Kim Donadio]

I'd be very careful with this. Histochemical even if it's on frozen section such as 88314 does not mean immunohistochemical which is 88342 to my understanding. To my understanding anytime you use a antibody it's a 88342 code. Now as far as being able to code for each margin say from 3-6 or 6-9 o'clock etc that seems like it would fall under the rules for each site to me kind of like we would charge a 88307 or 88309 for excision with margins instead of a 88305 which pays less. I personally recommend this not be left in the hands of google or even histonet. Good information comes from both but you might just want to put a call into American society of MOHs and ask. Because over billing is serious business and can get you in a lot of trouble. I only say this because usually in MOHs you'll get the whole specimen which your checking for margins. Then any piece after that would be a separate specimen example that would be part " B " which you could charge separate for.  And since different docs do this differently making a call couldn't hurt then you could come and share what they say with us :)
