TL;DR: use your own login, and give your biller their own

Use your own NH MMIS login. Your Organization Administrator creates a separate login for your biller and assigns Provider – Billing Staff; checking eligibility or payments may need other staff roles. Provider enrollment is a separate process. Official portal guidance.

Who needs their own NH MMIS Health Enterprise login

The Organization Administrator manages individual user accounts and their roles. A biller working on claims needs the Provider – Billing Staff role, while Provider – Eligibility Staff and Provider – Financial Staff cover different tasks. Our recommendation: keep each login in the named user’s control, including recovery details and any MFA offered, and never share your password. Official portal guidance.

Before you create access

If your practice is already registered, ask its Organization Administrator to create your account. If the enrolled provider has no web access, have the Title XIX provider ID and the matching SSN or FEIN ready for provider registration. The public registration instructions say credentials are mailed to the address on file. Official portal guidance.

Account setup steps

Already enrolled: open the portal’s Register Here route and follow the provider web-registration instructions. Use the provider information from the enrollment record. Staff joining an existing organization should go through its administrator instead of registering a duplicate organization. NH MMIS web-registration instructions.
