The Premium Transparency Act seeks to increase accountability and transparency within the health insurance industry by requiring detailed public disclosure of financial information from health insurers and Medicare Advantage plans. Starting January 1, 2027, health insurance issuers offering group or individual coverage must submit and publish on their websites the percentage of total premium revenue spent on claims, quality improvement, and administrative costs, along with the percentage of revenue they retain. Similarly, Medicare Advantage organizations will be required to disclose their total revenue, the amounts and percentages spent on incurred claims and non-claims costs, and the difference between their Medical Loss Ratio (MLR) numerator and denominator. This bill also mandates that health insurance Exchanges incorporate this newly required financial data into their comparative information for qualified health plans, starting with plan years beginning on or after January 1, 2029. This aims to provide consumers with more comprehensive data when selecting health plans. Furthermore, the Secretary of Health and Human Services is directed to issue guidance by January 1, 2028, for group health plans, health insurers, and Medicare Advantage organizations. This guidance will standardize the provision of information on plan benefits and coverage in a plain English format . Key aspects to be covered include monthly premiums, annual deductibles, out-of-pocket maximums, provider network types, the plan's share of total allowed costs, and standard cost-sharing amounts for various types of care such as primary, specialist, and emergency services. Additional features like wellness programs and eligibility for health savings accounts will also be included, ensuring consumers receive clear and comparable information.
