Title 42 › Chapter CHAPTER 7— - SOCIAL SECURITY › Subchapter SUBCHAPTER XVIII— - HEALTH INSURANCE FOR AGED AND DISABLED › Part Part D— - Voluntary Prescription Drug Benefit Program › Subpart subpart 2— - prescription drug plans; pdp sponsors; financing › § 1395w–112
Require companies that run standalone Medicare drug plans (PDP sponsors) to be state-licensed health insurers where they sell plans, take financial responsibility for the benefits they offer, and may buy insurance to cover some of that risk. If a sponsor can’t get a state license, the Medicare official (the Secretary) can waive the rule if certain conditions are met, but then the sponsor must meet federal solvency and capital rules the Secretary must publish by January 1, 2005 (with some special timing rules tied to January 1, 2008). The Secretary must have a contract with a sponsor before people can enroll and before the sponsor gets Medicare payments. Some rules that apply to Medicare Advantage contracts also apply here. A sponsor that runs a “fallback” plan is limited in offering regular PDP plans in the same area. Require timely pharmacy payments and other protections. Pharmacies must be paid for “clean” claims within 14 days for electronic claims and 30 days for paper claims. A clean claim is one that has no missing information; sponsors must tell a pharmacy within 10 days for electronic claims or 15 days for paper claims if something is missing. If payment is late, the sponsor must pay interest equal to the weighted average interest on 3‑month Treasury bills plus 0.1 percentage point, unless there is an emergency like a natural disaster. Long‑term care pharmacies get 30–90 days to submit claims. If a sponsor uses cost‑based pharmacy payment rules, it must update those prices at least once every 7 days starting January 1 each year. Starting for plan years on or after January 1, 2028, pharmacy benefit managers (PBMs) working for PDP sponsors must have written agreements that forbid hidden or tied payments except for flat, fair market value “bona fide service fees,” require detailed annual reports to sponsors and the Secretary (first due July 1, 2028) with drug use, prices, rebates, fees, and related data, let sponsors audit the PBM at least once a year, return money that violates the rules, and reimburse sponsors for penalties caused by PBM failures. Sponsors must pass certain recovered amounts to the government by plan years beginning January 1, 2029. Confidential data can only be shared for government oversight (for example with the Comptroller General, CBO, OIG, or the Attorney General) and must not identify specific companies or contract prices when publicly reported. Key terms defined include affiliate (related entities), bona fide service fee (flat fee for real services at fair value), and pharmacy benefit manager (anyone who negotiates prices or runs drug benefits).
