The committee print with the manager's amendment of H.R. 3076 would require all USPS workers, annuitants, and dependents to enroll in the new Postal Service Health Benefits program. Certain USPS annuitants and their dependents who are eligible to enroll in Medicare Part B would be required to do so. On net, CBO estimates that enacting the legislation would reduce direct spending, primarily because spending on prescription drugs for USPS annuitants would be covered under Part D, where manufacturers pay statutory discounts. The mechanisms in this version of H.R. 3076 are similar to a version of the bill that CBO analyzed in July 2021. Relative to that version of H.R. 3076, this legislation would require more USPS annuitants to enroll in Part D, which would require manufacturers to pay more discounts.
