Provider registration is an online process. The application form must be completed and submitted in one session; you will not be able to save and complete the application at a later time.
Once your email account has been verified, you will receive a follow up email confirming your registration with the Commission. Please retain the confirmation email for your records. It contains the Username you created during registration, which you will need to log into the Provider registry (OneStop Portal), as well as your MMCC Provider ID Number.
Once your registration has been confirmed, you can log into the Provider registry (OneStop Portal) to access your account and issue written certifications to patients registered with MMCC.
Your initial registration is valid for two years or until your Maryland Board license expires, whichever comes first. Prior to that expiration, you will be notified via email by MMCC that your expiration date is approaching. You will need to renew your Maryland Board license first, then subsequently log into the Physician registry (OneStop Portal) to renew your MMCC registration. Renewal registrations are valid for two years and the expiration will coincide with your Maryland Board license expiration date.
