Pt came in with a commercial payer as primary and Medicare as secondary. Provider billed 99213 and code 94664 for nebulizer demonstration (no treatment, just a demonstration). The commerical payer denied the 94664 as being non-covered. Now, one of the billers wants to bill this to Medicare with modifier GY attached. Is GY needed here? I'm not sure but I don't think that neb teaching is an excluded service by Medicare (unless billed in conjunction with a neb treatment then it is unless performed on separate encounters, then you use -59).
Would we use modifier GY for this?
Thanks.
