In short

  • Answer every OASIS item from what you see and assess at the visit, using the current OASIS guidance.
  • Make sure your OASIS answers match the rest of your assessment and notes.
  • Only you, the assessing clinician, may change your answers, and only if your assessment supports it.
  • Give the patient the OASIS privacy notice at the first visit and record it.
  • Each OASIS must be sent to CMS within 30 days of the assessment. The Agency sends it much sooner.
  • Never share a patient’s OASIS data outside the care team.
