MolDX: MGMT Promoter Methylation Analysis
L36113
Effective: August 7, 2025
Updated: December 31, 2025
Policy Summary
MGMT promoter methylation analysis is covered for adult patients (age >=18) with high-grade malignant glioma (e.g., glioblastoma multiforme, anaplastic astrocytoma) when the patient can tolerate temozolomide or radiation and the treating physician will use results to guide first-line adjuvant therapy choices. Coverage is conditional on the expectation that adjuvant therapy is potentially beneficial; the policy does not list specific claim forms or frequency limits and excludes testing for non-high-grade glioma and pediatric patients.
