Effect of Proper OASIS-E1 Review and ICD-10 Coding on Utilization Management of Clinical Staff In Home Health

In home health, accurate documentation plays a key role in making sure patients receive the right care at the right time. When assessments and coding are done correctly, it helps avoid unnecessary treatments and ensures that clinicians can focus on what patients truly need.

Proper documentation and data collection can help home health agencies determine the services a patient needs and how to allocate resources effectively, also known as utilization management. It also establishes a solid foundation that enables clinicians to make informed decisions about utilization. 

At K&K Healthcare Solutions, we understand the importance of a thorough OASIS-E1 review and accurate ICD-10 coding in supporting strong utilization management. In this guide, we’ll explain how OASIS contributes to the assessment process, why proper coding matters, and how both elements work together to create an effective, patient-centered plan of care.

OASIS & Its Relation to the Comprehensive Assessment

The Outcome and Assessment Information Set (OASIS) is a standardized assessment tool required by Medicare for use in home health. It helps clinicians assess a patient’s condition and develop a personalized care plan. OASIS data also serves as an outcome measure, allowing providers to track a patient’s progress over time.

Medicaid home health providers in states that follow Medicare Conditions of Participation (CoPs) must complete a patient-specific, comprehensive assessment that includes the most current version of OASIS using the standardized language and groupings provided.

By integrating OASIS into the comprehensive assessment, clinicians can make more informed decisions, develop more effective care plans, and improve overall patient outcomes.

The Challenges of OASIS-E1 Data Collection

  • Adjustment to New Guidelines: Each iteration of OASIS requires an onboarding period. With OASIS-E1 updates, even experienced clinicians must learn new response formats and scoring methodologies, which increases the risk of error during transitions.
  • Overuse of Default Responses: It can be tempting for clinicians to reuse the same response options multiple times for a patient. However, this can skew the data and create an unclear picture of the patient’s condition, leading to underutilization or overutilization of services. 
  • Inconsistencies in Data Collection: Clinicians often collect data and interpret patient responses in different ways, which can affect the reliability of the OASIS data. These discrepancies make it harder to create a cohesive and actionable care plan.
  • Improper Training: Without practical education and real-world training, staff may struggle to understand the clinical intent behind OASIS questions or how to ask them accurately.

Unclear OASIS Questions: Not all of the questions in OASIS are cut and dry, and some can even stump the most seasoned clinicians.

Building Clinician Confidence with OASIS-E1 Data Collection

When it comes to the accuracy of OASIS data, a lack of clinician confidence indicates a need for improved education and training. When clinicians fully understand the structure and purpose of OASIS-E1, their assessments become more accurate, consistent, and clinically useful.

Our team at K&K Healthcare Solutions offers extensive OASIS education modules and training that dive into the specifics of data collection and how to improve your OASIS assessments. Our training equips teams to:

  • Navigate difficult assessment items with clarity
  • Standardize documentation practices
  • Increase inter-rater reliability
  • Improve patient-centered care planning

For agencies seeking additional support, our outsourced OASIS review services provide an extra layer of assurance. Each review includes a detailed audit, coding verification, and expert recommendations that help prevent costly errors and ensure regulatory compliance.

Why Proper ICD-10 Coding is So Important

ICD-10 coding is the clinical language of home health documentation. With over 70,000 diagnosis codes available, precision in code selection is essential—not only for billing but for driving accurate care plans and ensuring compliance with Centers for Medicare & Medicaid Services (CMS) guidelines.

The most recent update, which took effect on October 1, 2024, introduced new codes and updated guidance that reflect the evolving needs of patients and current care strategies. Incorrect or vague coding can lead to underpayment, denied claims, and even audits. More importantly, it can hinder the delivery of appropriate patient care.

How ICD-10 Coding and OASIS Work Together

ICD-10 coding and OASIS-E1 inform and support each other. Together, they serve as the foundation for:

  • Establishing medical necessity
  • Determining the case-mix grouping under PDGM
  • Guiding care planning and frequency of services
  • Evaluating clinical outcomes and agency performance

For example, a mismatched diagnosis code in the assessment may not support the interventions laid out in the care plan, triggering a red flag during audits or payment reviews.

Best Practices to Ensure Proper ICD-10 Coding

To ensure your agency’s coding remains accurate and compliant, we recommend following industry best practices:

  • Ensure High-Quality Medical Documentation: You can only code the data you have. Thorough, in-depth documentation provides certified coders with the necessary information to accurately record patient information and input the correct home health ICD-10 codes. 
  • Stay Up-To-Date: With the recent update to the ICD-10, coders need to keep up with the latest information. This way, their coding remains as accurate as possible. 
  • Consider Certifications: Professional home health coders often earn certifications, such as the Homecare Coding Specialist – Diagnosis (HCS-D), to verify their expertise and hone their skills.
  • Invest in Outsourced ICD-10 Coding: If your agency is struggling to keep up with ICD-10 coding demands, consider outsourcing to companies such as K&K Healthcare Solutions. Our team of certified coders will take care of the work for you, so your team can focus on providing high-quality patient care.

Creating An Optimal Plan of Care

These OASIS items, ICD-10 coding, and comprehensive assessment all come together to help clinicians create an extensive plan of care. This plan of care outlines the intended treatment interventions and the patient’s goals. 

Clinicians use all of this information to determine the patient’s needs and develop a plan to meet those needs. They require extensive data collection and accurate documentation to create an effective care plan tailored to the patient’s specific condition.

Proper Preparation Creates Optimal Utilization Management

With this plan of care in hand, here is where utilization management comes into play. Clinicians and home health agencies take a look at the plan of care and determine which services the patient needs and how often they’ll need them. From nursing to home aide, the goal is to find the right service for that specific patient. 

These plans are often set in 60-day episodes, during which clinicians determine the number of visits per week a patient needs during that period. If the patient requires treatment for longer than 60 days, clinicians will conduct another OASIS and assessment within the last 5 days of the 60 days. From there, they will reevaluate the patient’s condition and determine the next steps. 

OASIS data, ICD-10 coding, and comprehensive assessment accuracy are directly tied to patient care. Clinicians can’t properly manage service utilization without the right information, and making the right decision for the patient depends on high-quality data and documentation.

K&K Healthcare Solutions Help Ensure Your Medical Documentation is Properly Done

Proper OASIS data collection and ICD-10 coding, along with the comprehensive assessment, ensure accurate and consistent utilization management for a home health agency. Without the correct information, clinicians struggle to create an effective plan of care that takes into account the patient’s needs. 

From OASIS review to outsourcing coding, our team at K&K Healthcare Solutions has what your agency needs to maximize utilization management in healthcare. We’ll help your agency enhance data collection and coding processes to create in-depth care plans that facilitate patients’ recovery.
