[Histonet] Billing question

[imhyper13 <@t> aol.com]

I have a question about billing practices for special stains and IHC.  We have a single billing code for all of our group 1 special stains. (88312).  For example, if you order an AFB, GMS and PASF, it would bill as 88312 x 3.  How does everyone else bill in this scenario?  We are being told that EACH stain in the group 1 needs it's own billing code.  Does anyone else do this?
Thanks
