Idaho's state Department of Insurance says no decision will come before December on whether Idaho will allow residents to keep existing insurance policies had initially been due for cancellation under President Obama's health care overhaul, the AP reports. Details on how health insurance companies would calculate rates for extended plans still aren't clear, the department said. Last Thursday, Obama said he'd allow insurance companies to keep selling these existing plans for another year, even if they do not meet certain Affordable Care Act criteria for coverage; the move followed criticism that he'd promised nobody would be forced out of their existing policy under the 2010 overhaul. But the decision requires state approval. Idaho is among numerous states still considering whether to follow Obama's lead.
