    Default Clia - mod qw question

    AAPC: Back to School
    There are 4 types of CLIA Certificates.

    1. A certificate of waiver allows a laboratory to perform only tests categorized as waived.

    2. A certificate of PPM allows a laboratory to perform tests categorized as provider perform microscopy procedures and, if desired, waived tests.

    3. A certificate of compliance allows a laboratory to perform tests categorized as waived, PPM, moderate or high complexity.

    4. A certificate of accreditation allows a laboratory to perform tests categorized as waived, PPM, moderate or high complexity.

    When a lab with certificate of waiver performs a waived test they are required to use modifier QW.

    When a lab has a ceritificate of PPM they are allowed to perform waived test, but CAN THEY BILL THE WAIVED TSET WITHOUT MOD QW?
