5-Day Assessment Window
The 5-day assessment window is the regulatory deadline for completing the start of care comprehensive assessment, including the OASIS: within 5 days after the start of care date, where the SOC date counts as day 0. A parallel 5-day window applies at recertification, when the assessment must be completed during the last 5 days of each 60-day certification period.
