Which Resource Should You Use?

The fastest way to check claim status and beneficiary eligibility is through the CSI/BE system. If you are not currently signed up for CSI/BE, you can find instructions for signing up, as well as a user guide for CSI/BE, on our CSI/BE page.

If you are not signed up for CSI/BE, you may check claim status and beneficiary eligibility using the IVR. The IVR is also available to provide additional information that is not available through CSI/BE. Below is a list of the information which you can find on the IVR:

  • Claim status
  • Beneficiary eligibility, which includes Part A and B entitlement dates, Medicare Advantage Plan enrollment, Home Health and Medicare Secondary Payer information
  • Beneficiary deductible
  • Total number of claims in process
  • Payment floor amounts
  • Allowable amounts
  • Outstanding check information
  • Offset information
  • Duplicate Medicare Remittance Notices (MRNs)
  • Status of a redetermination case
  • Beneficiary CMN history

For instructions on using the IVR, please consult the IVR User Guide. For an abbreviated version, consult the IVR Flow Chart.

For information which cannot be found on the IVR or through the CSI/BE system, suppliers may contact our Customer Service hotline.

Three Levels of Customer Service

When calling Customer Service, you will initially speak to a Tier 1 CSR. Tier 1 CSRs are capable of handling most supplier inquiries. In some cases, Tier 1 CSRs may need to transfer the call to a Tier 2 CSR (also known as the Help Desk). If a callback is required, a Tier 2 CSR will return your call within 10 business days.

If you have a complex inquiry that goes above and beyond the normal scope of a Tier 1 or Tier 2 CSR, the inquiry will be forwarded to the third level of Customer Service, the Provider Relations Research Specialist (PRRS) team. The PRRS will research the inquiry and respond either by phone or by mail within 45 business days.
