The Centers for Medicare & Medicaid Services (CMS) released a revised Workers’ Compensation Medicare Set-Aside Arrangement (WCMSA) Reference Guide (“Reference Guide”) Version 4.0 on April 1, 2024. This Reference Guide replaces Version 3.9 which was released on May 15, 2023. There are a few notable changes when comparing the two Reference Guides.   

Changes in This Version 4.0 of this Guide Include the Following Changes:

  • Instruction specific to beneficiaries has been added to encourage them to use their access to the portal for the most efficient method of submitting attestations (Sections 11.1.1 and 17.5). This user-friendly mechanism which allows CMS to gain potentially more MSA spending information than it has received via traditional mailing, may lead to CMS denying more future medical claims or potentially considering whether recovery of future medical payments that slipped through the cracks is viable. 
  • The CDC Life Table link was updated (10.3) – available to view here.


To download the new WCMSA Reference Guide v4.0 click hereThis guide reflects information compiled from all WCMSA Regional Office (RO) Memoranda issued by CMS, from information provided on the CMS website, from information provided by the Workers Compensation Review Contractor (WCRC), and from the CMS WCMSA Operating Rules. The intent of this reference guide is to consolidate and supplant all historical memoranda in a single point of reference. Please discontinue the reference of prior documents.
