Title 42 › Chapter CHAPTER 7— - SOCIAL SECURITY › Subchapter SUBCHAPTER XVIII— - HEALTH INSURANCE FOR AGED AND DISABLED › Part Part C— - Medicare+Choice Program › § 1395w–27a
Sets rules for Medicare Advantage (MA) regional plans. The Secretary must create MA regions by January 1, 2005, and can change them after studying insurance markets. There must be at least 10 and no more than 50 regions. Regions should help make regional plans available to all eligible people, including those in rural areas. A regional plan’s service area is the whole MA region, and a plan can be offered in more than one region. Regional plans must use a single deductible for traditional Medicare benefits (the plan can treat in-network and preventive services differently) and must include catastrophic out‑of‑pocket limits for in‑network benefits and for all traditional Medicare benefits. Plans offered in 2006 or 2007 must report yearly cost totals to the Secretary for traditional Medicare benefits and certain rebate-connected supplemental benefits, excluding administrative costs to get “allowable costs.” If allowable costs are 97%–103% of the plan’s “target amount,” there is no payment change. If allowable costs are >103%–108%, monthly payments rise by 50% of the amount over 103%; if >108%, payments rise by 2.5% of the target plus 80% of the amount over 108%. If allowable costs are 92%–<97% of target, payments are cut by 50% of the shortfall from 97%; if <92%, payments are cut by 2.5% of the target plus 80% of the shortfall below 92%. Contracts must let the Secretary get needed information and audit records. The law also sets how regional payment benchmarks are calculated from local benchmarks, plan bids, and a national market‑share percentage; lets an organization pick one local coverage decision to apply across a region; and allows special payments to certain essential hospitals when plans cannot reach a contract, with $25,000,000 available in 2006 and that amount rising each year by the market‑basket percentage. Definitions in one line each: MA region = geographic area set by the Secretary; allowable costs = plan costs for the listed benefits minus admin costs; rebatable integrated benefits = certain non‑drug supplemental benefits tied to rebates; target amount = sum of FFS payments, beneficiary premiums, and applicable rebates minus admin assumed in the bid; statutory national market share percentage = share of Medicare‑eligible people nationally not enrolled in MA in the reference month; reference month = the most recent month in the prior year with available data.
