Wiki medicare 36415 and modifier 90

[Libby C]

I am looking for documentation that tells me whether Medicare requires a modifier 90 on a 36415 if an outside reference lab is used. Any help would be appreciated. Thanks

I use a 90 modifier on ll send out labs, regardless of the payor. I don't know if it is required, but I have never received a denial for using it.

For Medicare, this modifier is used by independent clinical laboratories when referring tests to a reference laboratory for analysis. In other words, a third party.
