CompuNet Clinical Laboratories offers a wide variety of molecular diagnostic testing to our patients. When billing claims for molecular testing to insurance carriers, your office may be required by the payer to provide a Z code on the insurance claim. Z codes are test-specific and supplemental but do not replace the AMA CPT® code provided on the claim.
