PPACA does specify ten (10) broad areas of coverage, but not a specific plan menu.
The IOM study was a disappointment to some because it did not specify benefits, as this would have been a good discussion starter and would have given DHHS some political cover. The IOM focused on an approach to making the decision, and it is to start with costs and then work into benefits.
IOM also suggested an annual review of the programs beginning in 2016, and some waiver flexibility for states to customize plans.
Not exciting, but very very important.
