Due to the delay in ICD-10 implementation, CMS has released a modified version of the OASIS C-1. The OASIS-C1 data item set was originally scheduled for implementation on October 1, 2014. But, five of the data items contained in OASIS-C1 require the use of ICD-10 codes. CMS has made interim changes to the OASIS-C1 data item set and process for reporting OASIS-C1 data.
