Summary of OASIS Data Set Changes (Version 1.40) / SQLGOLD 205
The following items will be deleted from the OASIS instrument for all time points:
2. New OASIS Item (M0245)
There will be one new OASIS item added to the OASIS data set to facilitate compliance with the
Health Insurance Portability and Accountability Act (HIPAA). This item will be identified as
item M0245 and will be activated in October 2003. The new M0245 will allow HHAs to use V-
codes at the existing M0230/M0240 items as part of the assignment of the appropriate diagnosis
code using the ICD-9-CM coding process.
3. Patient Tracking Sheet
The following items will be removed from the OASIS instrument and placed on a Patient
Tracking Sheet. These items will be collected and submitted at the start of care assessment and
only updated when an item changes. This tracking sheet will be a part of the patient ’s clinical
Tracking Sheet – Complete at SOC..Update only as necessary.

6. Reduced OASIS Collection at Recertification/Follow-up
The OASIS data set used at Reason for Assessment (RFA)4 and RFA 5, i.e., follow-up and
other follow-up, has been substantially reduced.For RFA 4 or 5 assessment conducted on or
after December 16, 2002, HHAs will be required to collect only those 23 items currently used to
generate a payment group for a patient ’s subsequent episode of care plus the discipline of the
person completing the assessment (M0080)and the date the assessment was completed (M0090).
7. Language to be added to the Follow-up and Other Follow-up Assessments OnlyAs a result of the changes proposed to the OASIS data set, it is necessary to add some new
language to appropriately direct clinicians through certain skip patterns in order to complete all
the necessary items on the revised assessments.The following language will be added to the
revised OASIS data set:
M0460"Skip this item if patient has no pressure ulcers"
M0476"Skip this item if patient has no stasis ulcers"
M0488"Skip this item if patient has no surgical wounds"
M0530"Skip this item if patient has no urinary incontinence or urinary catheter presence"
