A filing fee required by Insurance Code §843.154 (concerning Fees), as determined by §7.1301 of this title (relating to Regulatory Fees), must accompany an application for a certificate of authority, unless the filing is made electronically through the NAIC's System for Electronic Rate and Form Filing, in which case the fees may not be attached to the filing. For filings made electronically, the department will send an invoice for the fees, and the HMO must pay, as provided in §7.1302 of this title (relating to Billing System). The fee is nonrefundable.
