Prior Authorization

No Prior Auth Required

Code is covered without prior authorization (high confidence)

Documentation Required

For services requiring a referring/ordering physician, the claim must report the referring/ordering physician's name and NPI.
Claims must include a valid ICD-10-CM diagnosis code that best describes the patient's condition for which the genomic sequencing service was performed.
Documentation should support that the panel's biomarkers meet Medicare coverage criteria (for example, NCCN Biomarkers Compendium Evidence Category I or 2A) and demonstrate associated clinical utility.
Laboratories and clinicians including non‑NCCN genes in panels are advised to adhere to regulatory and institutional oversight mechanisms to document clinical validity and utility.

Key Coverage Criteria

Targeted genomic sequence analysis panels for hematolymphoid neoplasms (including acute myelogenous leukemia, myelodysplastic syndromes, and myeloproliferative neoplasms) are covered when the panel contains at least 5 gene tests for molecular biomarkers that meet Medicare coverage criteria (for example, NCCN Biomarkers Compendium Evidence Category I or 2A) and are consistent with NCCN recommendations.
Targeted genomic sequence analysis panels with 5–50 genes (CPT 81450 or 81451) or 51 or more genes (CPT 81455 or 81456) are represented by these CPT codes and may be used when the panel meets the minimum 5-gene and evidence requirements above.
Minimal residual disease (MRD) testing in myelodysplastic syndromes (MDS) for single-gene tests may be covered when the test is medically reasonable and necessary for the individual patient's care.
CPT codes 64400-64530 for peripheral nerve blocks may be reported on the date of surgery when performed for postoperative pain management only if the operative anesthesia is general anesthesia, subarachnoid injection, or epidural injection and the adequacy of intraoperative anesthesia is not dependent on the peripheral nerve block.
Peripheral nerve block services that are separate, medically necessary services which cannot be rendered by the surgeon may be reported if the surgeon documents the reason for referral and the additional services are justified in the medical record.
