Billing and Coding: MolDX: Molecular Testing for Risk Stratification of Thyroid Nodules

Molecular testing for risk stratification of thyroid nodules is covered per MolDX LCD L39720, generally limited to a single test per patient lifetime. A second test for a separate, unrelated indeterminate thyroid nodule may be considered with supporting documentation; specific claim submission requirements include reporting the appropriate CPT and ICD-10-CM codes, entering 1 unit of service, and placing the DEX Z-Code adjacent to the CPT code in the designated claim fields (with no extra characters on SV101-7).

"Molecular testing for risk stratification of thyroid nodules is covered consistent with MolDX Local Coverage Determination L39720."
