The train wreck continues.

WASHINGTON (Reuters) – President Barack Obama’s decision to delay implementation of part of his healthcare reform law will cost $12 billion and leave a million fewer Americans with employer-sponsored health insurance in 2014, congressional researchers said Tuesday.

The report by the non-partisan Congressional Budget Office is the first authoritative estimate of the human and fiscal cost from the administration’s unexpected one-year delay announced July 2 of the employer mandate – a requirement for larger businesses to provide health coverage for their workers or pay a penalty.

The analysts said the delay will add to the cost of “Obamacare’s” insurance-coverage provisions over the next 10 years. Penalties paid by employers would be lower and more individuals who otherwise might have had employer coverage will need federal insurance subsidies.
