Oasis and ICD-9/10

A revised version of the OASIS-C1 data item set was approved by the Office of Management and Budget on February 6, 2014, and this version of OASIS was scheduled for implementation on October 1, 2014. However, five of the data items contained in OASIS-C1 require the use ICD-10 codes. Since ICD-10 has been delayed until at least October 1, 2015, the Centers for Medicare & Medicaid Services has made interim changes to the OASIS-C1 data item set and process for reporting OASIS-C1 data.

Visit the CMS website for more information and PDFs of the OASIS-C1/ICD-9 version data item set and a list of changes made to OASIS-C1 to create this new version.
