Medicare Part B Mailing Addresses for Mental Health Claims: A State-by-State Guide

Submitting Medicare Part B claims for mental health services can be overwhelming—especially when you're unsure where to send them. Using the wrong address can delay payments, cause denials, or even lead to compliance headaches.

That’s why we’ve created this comprehensive, state-by-state mailing address guide to help you streamline the process and reduce administrative burden.

Why the Right Mailing Address Matters

While most Medicare claims are filed electronically, many mental health providers still need to send paper claims, appeals, attachments, or documentation through the mail.

To avoid rejections or delays:

• Always mail claims to the correct Medicare Administrative Contractor (MAC) for your state.

• Keep this list handy for reference or compliance documentation.

• Recheck MAC websites annually, as mailing addresses can change.
