From the Billing Group drop-down, you can create a new billing group, or select an existing billing group to apply to the Master Plan Instance. Each Master Plan Instance must be associated with a billing group. Refer to the below screenshot and corresponding descriptions when creating a new billing group on this screen.

To add a Supplemental Plan to the Master Plan Instance, click the Add Supplemental Plan button.

Billing Responsibility
For a child account, select from the following options for Master Plan Instances from the Billing Responsibility drop-down:
- Self Pay
- Parent Pay with Child Usage Rules
- Parent Pay with parent Usage Rules
If you selected a parent pay billing responsibility, then you will need to select a Master Plan Instance from the displayed list of self pay Master Plan Instance that will have payment responsibility for the child account.
For more information, please see the important notes about parent‐child accounts.
Note: When a Master Plan Instance on the child account is defined as either of the two parent pay options, the Master Plan Instance on the child account must be mapped to a Master Plan Instance on the parent account for the balance to transfer to the parent account.
