What is a high case audit, and why is it important?

Created by Kelly Knudsen, Modified on Fri, 19 Jan at 10:04 PM by Kelly Knudsen

A high-case audit, also known as a catastrophic or large claim review, is an in-depth examination of individual insurance claims or benefit claims that exceed a certain predefined threshold. These claims are typically significantly larger or more complex than the average claims processed by an insurance company or benefit plan, and they may involve high-dollar amounts or severe medical conditions. High-case audits are conducted to ensure the accuracy, appropriateness, and compliance of these exceptional claims with the terms of the insurance policy or benefits plan.


The importance of high-case audits lies in several key factors:


  • Financial Impact: High-dollar claims can have a substantial financial impact on an insurance company or benefits plan. Auditing these claims helps identify errors, overpayments, or fraudulent activities that can result in cost savings and financial protection for the organization.
  • Accuracy and Compliance: Ensuring that high-value claims are processed accurately and in compliance with policy terms is essential. Errors or discrepancies in these claims can lead to legal disputes, reputational damage, and financial losses.
  • Fraud Detection: High-case audits are particularly crucial for detecting potential fraud or abuse. Large claims may be more attractive targets for fraudulent activities, such as exaggerating medical expenses or submitting false information. Identifying and preventing fraud is essential to protect the integrity of the insurance or benefit plan.
  • Risk Management: High-value claims can present unique risks and challenges. Audits help assess the validity of these claims and identify any issues that may require additional risk management strategies or preventive measures.
  • Provider Relationships: Auditing high-value claims can also involve reviewing the practices of healthcare providers involved in the treatment. This can help maintain strong provider relationships and ensure that providers adhere to contractual agreements and medical standards.
  • Compliance with Regulatory Standards: Insurance companies and benefit plans often need to comply with regulatory requirements related to large or catastrophic claims. High-case audits help ensure that these regulatory obligations are met.
  • Participant Confidence: When participants in an insurance plan or benefits program see that high-value claims are thoroughly reviewed and processed accurately, it can enhance their confidence in the plan's integrity and fairness.
  • Data and Insights: High-case audits generate valuable data and insights that can be used to improve claims processing procedures, inform future underwriting decisions, and enhance fraud detection methods.


In summary, high-case audits are a risk management and compliance tool that organizations use to carefully review and assess large or complex insurance or benefit claims. By conducting these audits, organizations can protect their financial interests, ensure compliance with policies and regulations, and maintain the trust of their participants or policyholders.
