Primary use account
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
Subordinate Access
- You must maintain subordinate access, and notify MassHealth of any change in information
- There is no limit to the number of subordinates assigned to an account
- If a primary user no longer has that role, the provider must assign a new primary user and remove the previous user's access
- The new primary user must then submit a Data Collection Form (DCF) along with a cover letter to let us know that the facility is changing primary user
- Providers cannot continue using the primary user ID of someone who is no longer employed
- Providers should audit their primary user(s) and subordinate(s) to be certain they are up-to-date
