This new study by Nachimson Advisors for the ICD-10 Coalition questions cost projections for the transition from ICD-9 coding to ICD-10 within the CMS proposed timeframe of October 1, 2011. The ICD-10 Coalition is seeking an extension of the timeframe due to the complexity of transition and cost estimates for implementation that are potentially higher than expected.
