Despite the year-long ICD-10 delay, OASIS-C1 implementation will move forward but with a new start date of Jan. 1, 2015, and some interim changes to the five coding items that required the use of ICD-10 codes, CMS says in a May 20 release.
The new item set will be referred to as the "OASIS-C1/ICD-9 Version," says CMS, and will take effect Jan. 1, 2015, and remain in effect until ICD-10 is implemented "or until otherwise determined by CMS." The current OASIS-C will remain in effect through Dec. 31, 2014.
The modified OASIS-C1 will replace the five coding items that required ICD-10 codes with the current, corresponding ICD-9 items, which include M1010 (Inpatient diagnosis), M1016 (Diagnoses requiring medical or treatment regimen change within past 14 days), M1020 (Primary diagnosis), M1022 (Other diagnoses) and M1024 (Payment diagnoses).
The final form and guidance manual are in the clearance process now, and once finalized, will be posted here. Also CMS has tentatively rescheduled the OASIS-C1 webinar for Sept. 3, at 2 p.m. EST.
CMS will change OASIS submission process
Home health agencies will no longer submit OASIS assessment data to CMS via their state databases, CMS says.
OASIS submissions to the state system will discontinue starting 6 p.m. EST on Dec. 26, 2014. The home health agency state submission system will no longer be used for OASIS submissions. Instead, starting Jan. 1, 2015, OASIS assessment data will be submitted to CMS via the Assessment Submission and Processing (ASAP) system, says CMS.
Updates to the payment grouper
CMS will update the home health payment grouper on Oct. 1, 2014, to accommodate assessments submitted Oct. 1, 2014 and later using OASIS-C and ICD-9 codes.
Then, an updated grouper will be released Jan. 1, 2015 to accommodate assessments submitted Jan. 1, 2015 and later using OASIS-C1 and ICD-9 codes.
