Wiki GY modifier/ABN

[LJones9199]

If a Medicare patient comes in for an E/M visit with diagnosis and at that time the physician orders a urinalysis for screening purposes only, can you append modifier GY and not do an ABN?

Thanks for any help

Modifiers GA, GY, GX, GZ

I think their is NCD for Urinalysis. Therefore I believe you would append -GA if an ABN had been signed. In no ABN has been signed, then you would use modifier -GZ. If the claim is statutorily excluded, you should append modifier -GY. Modifier -GX is used when a voluntary ABN is issued, when it is not required.
