How We Assist You

When calling Customer Service, you will initially speak to a Tier 1 Customer Service Representative. Tier 1 representatives can handle most supplier inquiries. In some cases, Tier 1 representatives may need to transfer the call to a Tier 2 representative (also known as the Help Desk). If a callback is required, a Tier 2 representative 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, 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.

Medicare beneficiaries and their representatives should contact 1.800.MEDICARE (1.800.633.4227) for all of their questions about Medicare. 1.800.MEDICARE is available to assist beneficiaries 24 hours a day, 7 days a week. For questions specific to DME MAC, beneficiaries should ask for "Medical Supplies" or visit the Medicare.govExternal Website website.
