Sources and clinical references Previous Next 1.1 Why “WNL” alone fails A Medicare auditor reviewing a home-health visit note does not see the patient. They see only the words on the page. When a system is documented as “WNL” or “no change,” the auditor cannot tell whether an RN-level provider was needed for that observation — and the visit becomes vulnerable to denial.
The principle
“WNL” describes a finding. Skilled documentation describes a finding plus the reason an RN’s judgment was required to obtain it — written so that a nurse who has never met the patient can act on it.
