The Basics of OASIS

New to the home healthcare industry?  Are you hearing the term OASIS being used frequently?  If you answered “yes” to either one of these questions then you may want to continue reading to learn about this key document.

OASIS is the acronym for the Outcome Assessment Information Set, which is a document based on a group of standardized data points that have been developed, tested and refined over two decades.  OASIS data is collected for Medicare and Medicaid patients, 18 years and older, receiving skilled services, not personal care, homemaker or chore services.  These data points collected address socioeconomic, environmental, support system, health status, and functional status matters.  The OASIS data provides a comparative measurement of home health care patient outcomes at two different points in time.  These different points in time include:

  • The start of care
  • Resumption of care following an inpatient facility stay
  • Recertification within the last five days of each 60-day recertification period
  • Other follow-up during the home health care period
  • Transfer to an inpatient facility
  • Discharge from home health
  • Death at home

All of the assessments require the clinician to have an in-person home visit with the patient, except for the transfer to an inpatient facility and death at home instances.  Not every OASIS item is completed at every assessment time point.  Some items are completed only at start of care while others only are done at time of discharge.

This information is critical for agencies because it is a valuable resource regarding quality improvement.  Outcomes are posted externally online and compared with data gathered nationally; therefore, potential patients can be much more knowledgeable about providers before making a decision.  Using OASIS as the foundation for reimbursement, the Centers for Medicare and Medicaid Services (CMS) have determined the agency’s performance will be a determining factor in the CMS payment rate in the future.  Those unable to meet minimum quality standards will receive a lower percentage payment on Medicare reimbursement.  A 5 star rating process is used to determine agencies’ outcomes – a direct result of OASIS answers.

Effective January 1, 2015 CMS revised OASIS C to OASIS C1- ICD-9 in order to insure home health’s assessment tools were more in line with other entities’ tools.  On October 1, 2015 when ICD-10 went into effect then OASIS C1-ICD-10-CM also was implemented.  The advent of ICD-10 resulted in many modifications and updates for OASIS.

Our experienced 5 Star team would be happy to educate you further on OASIS and the changes that have been implemented recently thanks to ICD-10.  Feel free to contact us to learn about our webinar or onsite training and/or consulting options.
