How will OASIS-C1/ICD-10 differ from the data set iteration currently in use (i.e., OASIS-C1/ICD-9)?

Homecare Insider, April 6, 2015

To accommodate the extended effectiveness of ICD-9 after the Protecting Access to Medicare Act of 2014 delayed the implementation of ICD-10, CMS made temporary changes to five data items in OASIS-C1 (the data set version created primarily to enable diagnostic coding with ICD-10) that would have required codes from the stalled version of the classification system. The resulting interim data set, called OASIS-C1/ICD-9, was instated on January 1 and will remain effective until the implementation of ICD-10.
OASIS-C1/ICD-10 will replace the five items that were modified in the OASIS-C1/ICD-9 iteration, meaning the forthcoming data set will largely mirror OASIS-C1, barring the updated name, as well as a few technical and typographical corrections.
