HELP - what is the correct place of service for IDTF inside an ASC?

[Iconkelly]

I'm billing TC for diagnostic radiology services for a mobile IDTF, and most of our services are provided in an ASC. If I bill with a place of service 24, the claims get rejected by Medicare because diagnostic services aren't reimbursed in an ASC. So, question is, what POS do I use? Do I use POS 15 even though the services are performed in an ASC, or do I use POS 11, or POS 49? I don't know which to use and my Medicare contractor (Palmetto GBA) won't answer my question...

I believe you have to use the ASC POS, to do otherwise would be fraud
