Health carriers must pay clean claims within 14 calendar days for electronic submissions or 30 calendar days for other submissions

Claims automatically become "clean claims" if the carrier fails to notify providers of deficiencies within 10 days (electronic) or 15 days (non-electronic) of receipt

Late payments require interest at the 3-month treasury rate plus 0.1%, and interest costs cannot count toward the carrier's medical loss ratio

Civil penalties include up to $25,000 per noncompliance determination plus up to $10,000 per week the violation continues

Aggrieved parties may bring private civil actions after providing 90-day written notice to the Insurance Commissioner if violations are not corrected
