Wiki HCPCS: G0481 vs G0659

[tralbrecht]

I need help. I am needing to know when G0481 can be billed vs G0659. I have a bill that isn't specific on the kind of test that was done, other than it was definitive. How do I know which one to use? I understand that G0659 is without Method or drug-specific calibration etc. but the bill doesn't state those specifics. I cannot find anything anywhere. Help please?!

Thank you in advance

This is a situation where I would contact the lab and find out what they did. G0481 covers 8-14 drugs and G0659 is per drug. 481 also requires more than one method and 659 does not.
