Register as a MassHealth provider on the Provider Online Service Center (POSC)

Download the Provider Enrollment Data Collection Form and Registration Instructions PDF | Word

Please note: Enrolled dental providers who need to access the POSC must also register by completing this form.

• Submit this form to MassHealth to identify a primary user (account administrator) for your organization. The primary user creates and inactivates users’ accounts and resets password.

Once the primary user is registered, they will need to:

• Create subordinate IDs for all other users within your organization
• Authorize access for additional users in your organization, as well as business partners such as billing agencies

Primary user account

The primary user is the person in your organization who is responsible for managing access to your organization’s data on the POSC. You can set up a primary user account to:

• Serve as the administrator of the account
• Provide access to more users by setting up subordinate IDs
• Link subordinate users in the POSC so they can view and submit transactions

Providers should audit their primary user assignment(s) to be certain they are up-to-date. Providers cannot continue using the primary user ID of anyone who is no longer employed or no longer represents your organization.

If a primary user has left that role, the provider must assign a new primary user and remove the previous user's access. The organization must then submit an Existing Provider Modification Data Collection Form (POSC-DC-PM) PDF | Word to let us know that the facility is changing its primary user.

Subordinate Access
 

• You must maintain subordinate access
• There is no limit to the number of subordinates assigned to an account
• Providers should audit their subordinate(s) to be certain they are up-to-date
