In 2011, Cedars-Sinai Medical Center in Los Angeles did what many providers were hesitant to do: It decided to tackle ICD-10 as an inevitable change and began its work to transition to the new system.

By contrast, only about 20 percent of providers believe they will complete or expect to complete all ICD-10 business changes by the third quarter of 2014 - the quarter before ICD-10 goes live, according to a survey from the Workgroup for Electronic Data Interchange.
