Guidance for CMS Research, Statistics, Data & Systems regarding Electronic Submission of Medical Documentation (esMD) for Review Contractors.

Issued by: Centers for Medicare & Medicaid Services (CMS)

Issue Date: September 23, 2020

The Electronic Submission of Medical Documentation (esMD) system allows Medicare providers and suppliers to exchange medical documentation and responses with Medicare review contractors (RCs). esMD enables the electronic submission of information, replacing paper documents where possible and reducing the burden on providers and suppliers.

If you are a review contractor interested in accepting or requesting documents electronically through esMD:

  1. Review the Introducing esMD to New Providers, Review Contractors, and Health Information Handlers (PDF) for details on requests and responses supported by esMD.
  2. Complete the following:
    1. Submit the esMD RC Onboarding Request Form (PDF).
    2. Follow the IDM Instructions.
    3. Follow the esMD Steps for Onboarding an RC to esMD (PDF).

Once the required credentials are approved and the infrastructure related activities are complete, the RC Client needs to be installed after reviewing the RC Client Java User Guide and Installation Handbook (PDF) or the RC Client Microsoft .NET User Guide and Installation Handbook (PDF).

Contact the esMD Help Desk for additional assistance.
