How to use the comparison

Start from the state where the service is furnished and open that contractor's version; its billing and coding article carries the diagnosis codes the claims system will test. For a group that bills in several jurisdictions, the version with the smallest covered list is the safe common denominator for pre-service review, and the version with the largest list shows what documentation can support an appeal elsewhere. The L37001 version is the one most searched for this title; the LCD lookup guide explains how jurisdictions are assigned, and the LCD hub lists every topic that more than one contractor has written.

Frequently asked questions

Why are there 4 LCDs called "MolDX: MGMT Promoter Methylation Analysis"?

Each Medicare Administrative Contractor writes its own Local Coverage Determination for its jurisdiction. 4 contractors publish a policy with this title covering 53 states; they often start from one contractor's text and then revise separately, so dates, criteria and diagnosis lists differ by jurisdiction.

Which "MolDX: MGMT Promoter Methylation Analysis" LCD applies to my claim?

The one written by the contractor that processes the claim: the A/B MAC for the state where the service is furnished, or the DME MAC region for equipment. The table lists each policy's states; open the policy for that jurisdiction and its billing and coding article.

How different are the diagnosis lists?

Among the 4 versions with a billing and coding article, the covered ICD-10-CM list ranges from 9 to 9 codes. A diagnosis accepted under one contractor can deny under another, which is the most common cause of coverage denials for multi-state groups.

When were these policies last revised?

Revision effective dates run from 2021-10-14 to 2026-07-09. A claim is judged against the version in force on the date of service.
