What CPT codes do you charge for a PEG XM assuming you do an IS phase, incubate but don't read at 37, then an AHG/CC phase?  Do you charge for the CPT codes for all 3 phases or only for those phases at which you read the test?

we treat PEG as another enhancement, so no difference in charges

Our PEG and LISS testing are built the same - with 3 charges - one per phase of testing.  We do observe for hemolysis with PEG testing after 37 incubation (do not spin) - so, no hemolysis is resulted in our LIS as negative.

We used to document no hemolysis at 37 on PEG testing but with EDTA samples preventing complement activation, that's sort of moot.  I guess maybe recording a result at 37 helps justify the charging for all 3 XM CPT codes.  Or maybe just the fact that we incubate it is enough to charge for that phase.  Our computer doesn't expect a result at 37, only IS, AHG & CC for PEG. The "incubation" CPT code description doesn't say it is read at that phase, I guess.  Maybe I am splitting hairs.
