The "Sunshine in Savings Act" aims to enhance transparency in the 340B Drug Pricing Program by establishing new reporting requirements for the Department of Health and Human Services, hospitals, and other entities involved in the program. Key provisions include the requirement for 340B covered entities to submit annual reports detailing the number of patients receiving covered drugs, total acquisition costs, reimbursements, net revenues, and costs associated with charity care. Additionally, hospitals must provide a rural patient benefit plan if they report over $2,000,000 in net 340B savings, and they are mandated to post a plain-language 340B patient notice and charity-care policy on their websites.

The bill also introduces claim-level 340B identifiers for fee-for-service and managed care organization claims to prevent duplicate discounts, in line with GAO/CMS guidance. Reports generated under this act will be based on aggregated data to maintain confidentiality, and the Department of Health and Human Services is authorized to adopt rules for compliance and enforcement. The act is set to take effect on January 1, 2027, and includes provisions for severability to ensure that if any part of the law is deemed invalid, the remaining sections will still be enforceable.
