We're here to help! Our team is committed to providing exceptional customer service—whether you need quick answers or personalized support.

Before calling, please try these self‑service tools for the fastest results:

• Eligibility & Claim Status - Start with the Noridian Medicare Portal (NMP)
• Enrollment Status
• Portal Password Reset

CMS requires the use of self-service tools when available. Our Customer Service Representatives may direct you back to these options when appropriate.

Most contact center services require authentication. Please have the following information ready:

• National Provider Identifier (NPI)
• Provider Transaction Access Number (PTAN)
• Taxpayer Identification Number (TIN)

If the IVR has trouble recognizing your information, here's how to reach a live agent:

1. After selecting from the main menu, enter your NPI.
2. If the system doesn't accept it, say "operator" or "agent," or press 0 during live‑support hours to reach a representative.
3. Then say "Part A" or "Part B" to connect with the right team.

Customer Service Representatives can assist with three inquiries per call for each NPI/PTAN.

Beneficiaries should contact 1‑800‑MEDICARE (1‑800‑633‑4227).
