SB 335 Montana Senate · 2025 Regular Session

Generally revise laws related to dental insurance

Senate Bill 335, known as the "Montana Dental Insurance Transparency and Accountability Act," establishes new regulations for dental insurance companies in Montana. It requires dental insurers to annually report their "dental loss ratio" (DLR), which measures the percentage of premium dollars spent on patient care, to the state's commissioner of securities and insurance. This reported DLR information, along with other plan details, will be made publicly available online for consumers to compare plans. The bill also mandates consumer rebates from dental insurers if their aggregated dental loss ratio falls below a certain threshold over a three-year period. This act applies to individual and group dental insurance plans, but excludes health plans with embedded dental benefits already subject to federal medical loss ratio requirements, as well as Medicaid and Healthy Montana Kids plans.

MODERATE
The bill was amended to streamline its title and clarify the definition of the 'medical loss ratio' by removing a specific requirement for rebates. New provisions were added to identify and report 'outlier' dental plans that deviate significantly from the average loss ratio, while also setting a safety threshold to prevent plans within 3 percentage points of the average from being flagged. Minor formatting adjustments were made to the page headers and section numbering.
Scope change
The bill's scope was slightly narrowed by removing a specific rebate mandate in the definitions section, but expanded regarding oversight through the addition of outlier identification and reporting requirements.
DEFINITION

Removed the specific instruction that excess funds must be refunded as a rebate from the 'medical loss ratio' definition.

REQUIREMENT

Added a requirement to calculate the average dental loss ratio and identify 'outlier' plans that fall outside one standard deviation of that average.

Established a protection clause stating plans within 3 percentage points of the average loss ratio cannot be considered outliers.

TECHNICAL

Adjusted the bill title to remove redundant words and fixed formatting inconsistencies in section headers and page numbers.
