To report a Molecular Diagnostic Test (MDT) service, submit the appropriate CPT code, include the appropriate DEX Z-Code identifier adjacent to the CPT code in the claim comment/narrative field, and enter 1 unit of service (UOS).
A molecular or genomic test may be covered when it provides new clinical diagnostic information that cannot be obtained from any other test or combination of tests and is reasonable and necessary for management of the Medicare beneficiary.
A molecular panel is coverable when the medical record documents that the entire panel is reasonable and necessary for the beneficiary’s specific medical problem and will be used in patient management.
Individual gene tests billed separately are coverable when the medical record documents that each individual gene test is reasonable and necessary for the beneficiary’s management.
When using next generation sequencing (NGS), genes assayed in parallel for the same indication on the same date of service are considered a single panel and may be billed as such when reasonable and necessary.
