Whatever states do about health insurance prices for older and younger adults, one thing remains certain: it will be unlikely to please everyone.

Frederic Blavin and his colleagues at the Urban Institute in Washington, D.C., have published data on how efforts to keep or eliminate age-based pricing differences might affect U.S. residents. The researcher published their data, in Health Affairs, an academic journal that focuses on the finance and delivery of health care. The researchers discusse the choices states will have before them should the Patient Protection and Affordable Care Act of 2010 (PPACA) be implemented as written.

Mired in controversy, legal wrangling and political argument since its signing into law in 2010, PPACA faces a multiple-front effort to get the law repealed outright in Congress, as well as to have it overturned in the Supreme Court. Oral arguments before the Supreme Court over the constitutionality of PPACA's individual mandate begin in March.
