“The annual Milliman Medical Index (MMI) measures the total cost of healthcare for a typical family of four covered by a preferred provider organization (PPO) plan. The 2012 MMI cost is $20,728, an increase of $1,335, or 6.9% over 2011. The rate of increase is not as high as in the past, but the total dollar increase was still a record. This is the first year the average cost of healthcare for the typical American family of four has surpassed $20,000.”
