The Department of Health and Human Services (HHS) has posted a notice correcting technical and typographical errors in its March 27, 2012 interim final rule implementing the new Affordable Insurance Exchanges under the ACA. The correction notice is effective May 29, 2012. HHS also has released an “Exchange Blueprint” for states to use to demonstrate how their Exchanges meet or will meet all legal and operational requirements associated with the state Exchange model (a state-based Exchange or a Partnership Exchange with HHS).
