Billing out 80100

For our substance use clients at our clinic we collect and handle the 80100 and transport to a outside lab tha performs the test. The lab bills us by invoice and not the insurance company. So we bill it out to the insurances. Does anyone know if we can only bill out 99000 and not the 80100 since we aren't performing the test?

re: Billing out 80100

Coverage of any service is determined by a member’s eligibility, benefit limits for the service or services rendered and the application of the Plan’s Medical Policy. For Medicare patient's you cannot bill a test that is not performed in the office. The lab performing the test must bill the service (Medicare).
For non-Medicare patient's check with payer regarding use of modifier -90.

re: Billing out 80100

We don't bill Medicare or any Medicaid's as well for the UA's, I adjust off the 80100. We get invoiced by the lab for our commercial and full fee clients. Therefore I always bill it out to those payors, however now I'm being advised that we can not bill it out and can only bill 99000 due to we don't have a CLIA certification on site. But if I'm correct here, the laboratory performing the test is who needs to be CLIA certified, not us for billing it. Am I correct or am I way off here? Thanks for your help.

re: Billing out 80100

CPT® code 80100 is used by a moderately or highly complex laboratory to bill for a single drug test that detects the presence or absence of multiple drug classes. For example, if a single test were able to detect the presence of ten different drug classes, the laboratory would bill a single unit of CPT® code 80100. 80100 is a non-waived test. The best way to do this is to bill handling charge and have lab bill test to insurance.
