Dental insurers must file annual dental loss ratio reports by March 1 with the Commissioner of Securities and Insurance, including data on enrollees, cost-sharing amounts, deductibles, annual maximum coverage limits, and enrollees who exceed those limits

The commissioner will calculate average dental loss ratios by market segment using 3-year aggregate data and identify insurers falling more than 1 standard deviation below the average as outliers

Insurers identified as outliers for 2 consecutive years become subject to a minimum dental loss ratio requirement, effective no sooner than 42 months after being designated an outlier

Insurers required to provide rebates must do so by August 1 of the fiscal year following the calculation year, with premium reductions allowed as an alternative to direct rebates

Effective June 1, 2025, with requirements applying to dental insurance policies issued or renewed on or after January 1, 2026; excludes health plans with embedded dental benefits subject to ACA requirements and Medicaid/Healthy Montana Kids coverage
