We have billed these codes to Medicare and Medicare has denied stating "provider not certified/eligible to be paid for this procedure/service on this date of service." Someone told us to file with modifier QW so we did but Medicare denied again stating "procedure code is inconsistent with the modifier used or required modifier is missing?" We are not familiar with "lab" codes or the "QW" modifier. If anybody knows anything about this please help...any suggestions or comments would be very helpful.
Thanks,
Kim
