Title 42 › CHAPTER 7 — SOCIAL SECURITY › SUBCHAPTER XVIII — HEALTH INSURANCE FOR AGED AND DISABLED › Part C — Medicare+Choice Program › § 1395w–27a
The Secretary must create Medicare Advantage (MA) regions across the 50 States and D.C. and publish them by January 1, 2005. There must be at least 10 and no more than 50 regions. The regions should help as many eligible people as possible get regional MA plans, especially people in rural areas. Before setting regions, the Secretary must study insurance markets. A regional plan can be sold in more than one region or nationwide. Regional plans must use one deductible for original Medicare benefits (not separate hospital and medical deductibles). That deductible can be different for in‑network care and can be waived for preventive services. Plans must also have a catastrophic out‑of‑pocket limit for in‑network benefits and a limit for total benefits. For plans offered in 2006 and 2007, the organization must report its allowable costs to the Secretary each year. “Allowable costs” are the plan’s cost for original Medicare benefits and certain integrated supplemental benefits, minus administrative expenses. The Secretary compares those costs to a target amount and adjusts monthly payments under set rules: no change if costs are 97%–103% of target; increases if costs exceed 103% (50% of the gap between 103% and 108%, and a larger formula above 108% including 2.5% of target plus 80% of the excess); reductions if costs are below 97% (50% of the shortfall down to 92%, and a larger reduction below 92% including 2.5% plus 80% of the deeper shortfall). Plans must give the Secretary cost data and allow audits. The Secretary and HHS staff may use the data only to run these rules. If an organization meets one State’s requirements in a region but not others, the Secretary can temporarily waive other States’ requirements while applications are processed. The Secretary computes a yearly region-specific non‑drug benchmark before each annual election period (starting 2006) from two parts: a statutory component and a plan-bid component using market shares and weighted plan bids. A plan sponsor can choose one local coverage decision to apply across the whole region. To keep networks adequate, the Secretary may pay an “essential hospital” when a plan cannot reach an agreement with the hospital, if the hospital shows costs exceed standard payments. Available funds for those payments were $25,000,000 in 2006 and then grow each year by the market basket percentage; payments come from the Federal Hospital Insurance Trust Fund.
