OASIS Coding & Review

Essential Home Health Care Solutions provides comprehensive OASIS coding and clinical review services designed to support accuracy, compliance, documentation integrity, and appropriate reimbursement. Our experienced clinical reviewers perform detailed reviews of OASIS assessments and supporting clinical documentation, helping agencies identify inconsistencies and documentation deficiencies prior to submission.

Our OASIS review services include:

• Start of Care (SOC), Resumption of Care (ROC), Recertification, Transfer, and Discharge reviews 
• ICD-10 diagnosis coding and sequencing review 
• OASIS item accuracy and clinical consistency review 
• Primary and secondary diagnosis documentation validation 
• Plan of Care and supporting clinical documentation review 
• Medication profile and order consistency 
• Therapy, MSW, HHA, and other discipline documentation review, as applicable 
• Review of supporting assistance, education, interventions, and measurable documentation 
• Vertical review within the current assessment and clinical record 
• Horizontal review across previous assessments and certification periods 
• Clinician corrections, feedback, and education when deficiencies are identified 

Our remote QA professionals monitor submitted documentation and work to provide timely OASIS review and feedback. Our goal is to complete reviews within 48 hours, allowing agencies to address identified issues promptly and keep documentation and billing processes moving efficiently.

Each assessment is evaluated both vertically, for consistency within the current assessment and supporting clinical record, and horizontally, for consistency with previous assessments and certification periods. Our reviewers evaluate whether OASIS responses and diagnosis coding are supported by the clinical documentation, including orders, medication profiles, therapy needs, assistance requirements, teaching and interventions, and other relevant clinical information.

Our goal extends beyond identifying errors. EHHCS works with agencies and clinicians to strengthen documentation practices, improve OASIS accuracy, support regulatory compliance, and reduce recurring documentation deficiencies through meaningful reviewer feedback and education.
