SECTION 1. Sections 131 and 226 of chapter 139 of the acts of 2012 are hereby repealed.

SECTION 2. Chapter 176O of the General Laws is hereby amended by adding the following section:-

Section 30.  (a) For the purposes of this section, “estimated rebate” shall mean (1) negotiated price concessions including, but not limited to, base rebates and reasonable estimates of any price protection rebates and performance-based rebates that may accrue, directly or indirectly, to a carrier during the plan year from a pharmaceutical manufacturer, dispensing pharmacy, or other party to the transaction based on the amounts the carrier receives in the prior quarter or reasonably expects to receive in the current quarter; and (2) reasonable estimates of any fees and other administrative costs that are passed through to the carrier and serve to reduce the carrier's prescription drug liabilities for the plan year based on the amounts the carrier received in the prior quarter or reasonably expects to receive in the current quarter.

(b) A carrier shall annually certify to the commissioner that, during the prior plan year, the carrier made available to the insured at least 80 percent of the estimated rebates received by such carrier by reducing the amount of cost sharing that it would otherwise charge at the point of sale except that the reduction amount shall not result in a credit at the point of sale.  Neither the insured nor the carrier is responsible for any difference between the estimated rebate amount and the actual rebate amount the carrier receives provided that such estimates were calculated in good faith.

(c) Beginning April 1, 2024 and annually thereafter, a carrier shall file with the division a report in the manner and form determined by the commissioner demonstrating the manner in which the carrier has complied with this section.  If the commissioner determines that a carrier has not complied with one or more requirements of this section, the commissioner shall notify the carrier of such noncompliance and a date by which the carrier must demonstrate compliance. If the carrier does not come into compliance by such date, the division shall impose a fine not to exceed $5,000 for each day during which such noncompliance continues.

(d) In making the disclosures required under this section, a carrier shall not publish or otherwise reveal information regarding the amount of rebates it receives, including, but not limited to, information regarding the amount of rebates it receives on a product-, manufacturer-, or pharmacy-specific basis. Such information shall be considered to be a trade secret and confidential commercial information, and shall not be a public record and shall be exempt from disclosure under clause Twenty-sixth of section 7 of chapter 4 or section 10 of chapter 66.  A carrier shall impose the confidentiality provision of this subsection on any vendor or third party that performs any services on behalf of the carrier and that may receive or have access to rebate or estimated rebate information.

(e) The commissioner shall adopt any written policies, procedures or regulations the commissioner determines necessary to implement this section.
