I just got notification from AHIMA that CMS just posted new information on the update for the ICD-10 PCS format files. So all of you that are actively training and working with ICD-10 PCS this is a GREAT resource.
CMS has a PDF file out there that walks you through the entire PCS Processes... and best of all it's free!!! Here's the CMS link. On the CMS site, it also has the 2012 information for ICD-10 cm. I'm hoping the CM informational update for 2013 will be out soon too! Happy Coding! L : )
