The 3 OASIS Manual Areas Surveyors Audit Most
These are the three sections auditors and surveyors cite the most when reviewing OASIS compliance.
1️⃣ Clinician Attestation & Legal Responsibility
From the OASIS-E2 Guidance Manual – Comprehensive Assessment section.
CMS states that the assessment is a legal document and that the clinician signing it attests that the OASIS responses reflect the patient’s condition. OASIS E2
Why agencies get cited
- OASIS responses not supported by documentation
- charting copied from prior visits
- inconsistent clinical narrative
2️⃣ Collaboration vs Direct Assessment
CMS allows collaboration with other staff, but the assessing clinician must determine the responses.
The manual states the clinician may gather input from other agency staff who had contact with the patient. OASIS E2
Common survey findings
- therapy determines functional scoring
- nurse copies therapy functional status
- no clinician verification
Surveyors expect the assessing clinician to confirm the status.
3️⃣ Supporting Documentation for OASIS Responses
CMS states responses must be supported in the patient’s clinical record.
Surveyors frequently review:
- functional scoring vs therapy notes
- fall history
- pressure injury staging
- cognitive status
- hospitalization risk factors
If documentation conflicts with the OASIS:
➡ The OASIS is considered inaccurate.
The Most Important Administrator Takeaway
When agencies fail OASIS audits, it is usually not the scoring rules.
It is:
• documentation inconsistency
• lack of clinician verification
• unsupported responses
