Title 42 › Chapter 7— SOCIAL SECURITY › Subchapter XVIII— HEALTH INSURANCE FOR AGED AND DISABLED › Part D— Voluntary Prescription Drug Benefit Program › Subpart 2— prescription drug plans; pdp sponsors; financing › § 1395w–111
Sets rules for how Medicare prescription drug plans pick their service areas, send in bids, and get approved. The federal official in charge must make regional areas for plans and usually make them match Medicare Advantage regions. Plans can cover one or many regions. Plan sponsors must send detailed bid materials for each plan, including what drugs and cost-sharing they cover, the plan’s actuarial value, how the bid breaks down (basic vs. supplemental costs, reinsurance amounts, and admin costs), the service area, and any request to change how financial risk is shared. The agency will give rules for how to calculate actuarial values, and plans must use accepted actuarial methods; sponsors can hire independent actuaries. The agency reviews and can negotiate bids. A plan is approved only if it follows the rules, its actuarial numbers are supported, the basic and supplemental parts of the bid are justified, and the plan design is not likely to unfairly discourage some people from enrolling. If needed to meet local access rules, the agency can approve a limited risk plan (one that asks for special risk-sharing) but only the fewest needed and only if the plan takes real financial risk. Full risk plans (those without special risk-sharing) can be approved without a set limit. For areas that still would lack coverage, the agency will run a separate process to pick an eligible fallback entity to offer a fallback plan that only provides standard coverage. Only one fallback plan per region is allowed. Fallback contracts pay actual drug costs plus performance-based management fees, last 3 years, and must charge a uniform monthly premium equal to 25.5% (or the percent set for 2030 and later) of the estimated average monthly per-person cost. The agency must report yearly on limited risk and fallback plans. The agency cannot interfere with drug-maker or pharmacy negotiations, force a specific formulary (except in narrow cases), or set drug price rules beyond certain laws. Plan sponsors must let State Pharmaceutical Assistance Programs coordinate benefits and may not charge unrelated fees.
