Auditing OASIS assessments (SOC, ROC, Recert, Follow-up, Transfer, DC) for accuracy, internal consistency, and CMS compliance - not just checking boxes, but catching coding errors that affect case-mix and quality scores. We need someone who can independently score and defend OASIS-E/E1 assessments - GG and M-item coding, sequencing, and how accuracy drives PDGM case-mix and HHVBP outcomes.
