Highmark Commercial Medical Policy - Pennsylvania
Medical Policy: L-190-004
Topic: MGMT Testing for Malignant Glioma Alkylating Agent Response
Section: Laboratory
Effective Date: November 13, 2017
Issue Date: November 13, 2017
Last Reviewed: June 2017

MGMT is the O6-methylguanine- DNA methyltransferase gene, which encodes an essential DNA repair enzyme. MGMT expression in tumors causes resistance to DNA-alkylating drugs. MGMT repairs the damage produced by these DNA cross linking agents.

MGMT promoter methylation testing is performed on paraffin embedded tumor tissue. Quantitative methylation-sensitive PCR is used to determine MGMT gene promoter methylation levels.

This policy is designed to address medical guidelines that are appropriate for the majority of individuals with a particular disease, illness, or condition. Each person's unique clinical circumstances may warrant individual consideration, based on review of applicable medical records.

Policy Position Coverage is subject to the specific terms of the member’s benefit plan.

MGMT Testing for Malignant Glioma Alkylating Agent Response may be considered medically necessary when the following criteria are met:

Procedure Codes

Professional Statements and Societal Positions

The National Comprehensive Cancer Network (NCCN, 2016 stated that:

  • MGMT promoter methylation is particularly useful in treatment decisions for elderly patients with high grade gliomas (grades III-IV).”
  • “Patients with glioblastoma that are not MGMT promoter methylated derive less benefit from treatment with temozolomide compared to those whose tumors are methylated.”

Place of Service: Outpatient

MGMT testing for malignant glioma alkylating agent response is typically an outpatient procedure which is only eligible for coverage as an inpatient procedure in special circumstances, including, but not limited to, the presence of a co-morbid condition that would require monitoring in a more controlled environment such as the inpatient setting.


The policy position applies to all commercial lines of business


Denial Statements

A network provider cannot bill the member for the denied service unless: (a) the provider has given advance written notice, informing the member that the service may be deemed not medically necessary; (b) the member is provided with an estimate of the cost; and (c) the member agrees in writing to assume financial responsibility in advance of receiving the service.
