Wiki Screen/Confirmation

[robertjsenese]

Good morning,
The clinical laboratory process is: when they receive a UDT,

1.) run it through an analyzer for a +/- result on 13 drugs (and validity)
2.) take the specimen and then run it through a Mass Spec for definitive result on drugs that are abused but not recognized on the analyzer (i.e. synthetic cannaboids, alcohol metabolites, etc.)

My question then is, is it acceptable to bill for the presumptive/qualatitive screen,
with G0431/80301
and then bill for the definitive profile from the confirmation test.

or should be only be billing for the confirmation.

thank you.

"A presumptive test may be followed by a definitive test in order to specifically identify drugs or metabolites."
AMA, CPT 2015, page 467

Okay, so i answered my own question,
it is acceptable using modifier 59.

However, to be reimbursed on both services, can they be on the same day?
or should the presumptive test be done on day 1, and the definitive test be done on day 2?

thank you

Date of service for lab tests should be the date the sample was collected from the patient, not the date the tests were actually performed.
