Risk adjustment: How clinical guidelines and scoring systems are used with HCC coding

 

Milliman and InterQual are two prominent organizations that provide clinical guidelines and scoring systems in the healthcare industry. These scoring systems, particularly when used in conjunction with Hierarchical Condition Category (HCC) coding, play a crucial role in risk adjustment and reimbursement methodologies in healthcare.

 

1. InterQual Scoring:

   - Purpose: InterQual is a decision support solution that assists healthcare professionals in making evidence-based decisions regarding patient care, utilization, and level of service.

   - Scoring System: InterQual utilizes a scoring system to evaluate the medical necessity and appropriateness of healthcare services. This scoring helps determine the level of care needed for a patient.

 

2. Milliman Scoring:

   - Purpose: Milliman offers various solutions, including Milliman Care Guidelines (MCG), to assist in care management and utilization review.

   - Scoring System: Similar to InterQual, Milliman provides scoring systems within its guidelines to evaluate the necessity and appropriateness of healthcare services. The scoring aids in decision-making related to patient care.

 

3. HCC Coding:

   - Purpose: Hierarchical Condition Category (HCC) coding is a system used for risk adjustment in healthcare. It is primarily employed in the context of Medicare Advantage and other value-based payment models.

   - Coding System: HCC coding involves assigning specific codes to various medical conditions and diagnoses. These codes are then used to assess the health status of patients and predict their healthcare costs over time.

 

4. Relationship between Scoring Systems and HCC Coding:

   - Risk Adjustment: Both InterQual and Milliman scoring systems contribute to the risk adjustment process. They help assess the severity of illness, expected resource use, and appropriateness of care, which are factors considered in risk adjustment models.

   - Documentation and Coding Alignment: The scoring systems may guide healthcare providers in documenting the severity and complexity of a patient's condition. This documentation is crucial for accurate HCC coding, as the codes should reflect the true health status of the patient.

 

5. Impact on Reimbursement:

   - Reimbursement Models: HCC coding influences reimbursement models, especially in Medicare Advantage plans. Accurate documentation and coding of chronic conditions can result in higher risk scores, which may lead to increased reimbursement for the healthcare provider.

   - Scoring Systems as Support: The scoring systems provided by organizations like InterQual and Milliman can serve as supporting evidence in justifying the medical necessity and appropriateness of care, aligning with the requirements for reimbursement.

 

In summary, both InterQual and Milliman scoring systems, when integrated with HCC coding, contribute to a comprehensive approach in healthcare. They aid in decision-making, care management, and risk adjustment, ultimately impacting reimbursement in value-based payment models. Healthcare organizations often use these tools in tandem to ensure both the quality of care and accurate reimbursement for the services provided.
