This bill amends Chapter 27-20.1 of the General Laws entitled "Nonprofit Dental Service Corporations" to require carriers offering dental benefit plans to submit information on their medical loss ratio. The information must include current and projected medical loss ratios for in-state claims, total claims for their plans, and the components of projected administrative expenses and financial information. The bill also specifies that certain expenses, such as marketing and sales expenses, claims operations expenses, and payroll expenses, are considered administrative costs for the purposes of calculating and reporting the medical loss ratio. If the medical loss ratio is less than 85%, the carrier must refund the excess premium to covered individuals and groups. The bill takes effect on January 1, 2024.
