About the Customer Support Department

When you call Customer Support at 866-590-672, you'll first speak with a Tier 1 customer support representative (CSR). Tier 1 CSRs can handle most supplier inquiries. In some cases, Tier 1 CSRs may need to transfer the call to a Tier 2 CSR. If a callback is needed, a Tier 2 CSR will call you back within 10 business days.

If your question is more complex than what a Tier 1 or Tier 2 Customer Support Representative can handle, we'll send it to our third level of Customer Support, the Provider Relations Research Specialist (PRRS) team. The PRRS will research the inquiry and get back to you by phone or by mail within 45 business days.

  • Giving general information about what Medicare covers.
  • Explain terminology and information found in the Supplier Manual.
  • Help with other complex issues.
