Authentication To ensure we protect our Medicare beneficiaries’ protected health information (PHI):
  • Some functions require you to input certain required elements before releasing results.
  • The information you enter must match the provider, beneficiary, or claim information on file.
Note: CGS can’t release the required elements via portal, website, or phone. Please make sure you have the correct information available. If not, please check your files, contact the patient or representative, or use another eligibility system to verify.
