Despite assurances that those content with current insurance plans could keep them after Obamacare becomes law, an estimated 50 to 75 percent of those with individual health coverage will have to replace their polices—and the Obama administration has known for three years. Sources in the Affordable Care Act say many Americans will receive a "cancellation" notice due to their policies not meeting standards of the upcoming law. The original policy stipulated policies from March 23, 2010, and on would be honored, but tweaks by the Department of Health and Human Services amended it to mandate a cancellation if any part of the policy was significantly changed after that date.
