After receiving the user ID and password, the primary user must take the following steps.
• Change the password. Once the primary user has registered, he/she must go to the Virtual Gateway at
https://gateway.hhs.state.ma.us/authn/index.jsp to change the password. A series of “I forgot my password”
questions under the “Manage My Profile—Authentication Questions” tab must be answered before the password
can be changed.
• Assign and link subordinate IDs. Once registered, the primary user must create a user account for each individual
user in the organization needing access to the POSC, and give permission to share data with other entities who
conduct business on their behalf. The primary user can also link an individual user who already has a user ID to a
new provider by selecting the “Administer Account” link.
• Assign an alternate primary user. It is suggested that the primary user assign a backup primary user with all of the
privileges of the primary user to perform the above steps in the primary user’s absence. MassHealth recommends
that primary users assign users only the access they need and not grant every user full access.
• Primary user changes. Providers must notify MassHealth of any changes to the primary user.
• Changing a Primary User. By checking the Change Primary User box, the prior primary user will be removed and the
person noted above will be assigned as the new primary user.
Your user ID and password will give you access to the POSC. You will also need these credentials to access the AVR system
to verify member eligibility.
When using the POSC, you will need your provider ID and service location number (PID/SL) to view reports, remittance
advices, letters, direct data entry (DDE), and Health Insurance Portability and Accountability Act (HIPAA) transactions.
MassHealth will mail the PID/SL to you separately.
Please remember that you must submit your national provider identifier (NPI) on the HIPAA batch transactions. If you are
an atypical provider (that is, not required to have an NPI), please include your PID/SL on your batch transactions.
