CMS is seeking the Office of Management and Budget’s (OMBs) approval for home health agencies to input ICD-10 codes into the OASIS-C1 data set.
 
In its supporting statement to the OMB, CMS says the OASIS-C1/ICD-10 form will enable the coding of ICD-10 codes when ICD-10 goes into effect Oct. 1 or thereafter.
 
OASIS-C1 had been slated for implementation on Oct. 1, 2014, but on April 1, 2014, Congress enacted legislation mandating ICD-10 not be implemented prior to Oct. 1, 2015.
 
The OASIS-C1/ICD-10 version retains all the updated clinical concepts, modified wording and improved clarity included currently in OASIS-C1/ICD-9, and reinstates codes from ICD-10, CMS says.
 
CMS is requesting the following changes be made to OASIS-C1/ICD-9:
 
OASIS-C1 change table from the ICD-9 to the ICD-10 version
 
OASIS-C1/ICD-9 item
