805 Mass. Reg. 5.03
Other than Municipal Employers, non-state funded employers whose employees, retirees, or survivors participate in Commission coverage as expressly mandated by state law shall directly reimburse the Commission for premium payments made on behalf of the employers' Insureds, together with a Commission fee. Reimbursing entities shall pay the Commission no later than 30 days from the date of the Commission's invoice. The Commission may include in its Commission fee a charge determined by the State Comptroller for late payment. Such late charge shall be billed separately and identified on a subsequent Commission invoice. Monthly invoices are available through the Commission's eligibility system, MAGIC, and invoices must be reconciled to the payment submitted to the Commission. If the entity does not pay the invoice in full, the Commission will bill the entity for outstanding balances until full payment is made or discrepancies are reported and reconciled. Failure to remit full payment may result in cancellation of coverage for that entity's enrollees.
