When billing with a GY modifier, is there an order in which the GY needs to be listed in when billing multiple modifiers?
When I need to use the GY modifier, I put it as the last one.
Example when I bill to medicare for non-covered services:
H2019 U1 HQ GY
They have been providing the correct Patient Responsibility COB information. If I do not provide that modifier, then I get a rejection with the amount listed as a contractual obligation. The secondary insurance then will not pay or pay correctly.
Hope this helps!
