Picture this: You receive a letter from your insurance carrier announcing an upcoming workers comp audit. Your stomach drops. You scramble through filing cabinets, wondering if you’ve kept the right records, classified employees correctly, or if your premium is about to skyrocket. Sound familiar?
You’re not alone. According to the National Council on Compensation Insurance (NCCI), approximately 75% of businesses have errors in their workers compensation classifications, potentially leading to significant premium miscalculations. Understanding the difference between a workers compensation audit and a workers comp review can save your business thousands of dollars and countless hours of stress.
In this comprehensive guide, we’ll break down everything you need to know about both processes, helping you navigate the complex world of insurance premium verification with confidence. Whether you’re preparing for your first audit or looking to streamline your compliance procedures, this information is essential for protecting your bottom line.
What Is a Workers Comp Audit? Understanding the Fundamentals
A workers compensation audit is a mandatory examination conducted by your insurance carrier to verify that your premium payments accurately reflect your actual business operations, payroll, and risk exposure during the policy period. Think of it as a financial reconciliation between what you estimated at the beginning of your policy and what actually occurred throughout the year.
When you purchase a workers compensation insurance policy, your premium is based on estimated payroll figures and employee classifications. However, businesses are dynamic—you might hire additional staff during busy seasons, expand into new service areas, or experience unexpected changes in your workforce composition. The insurance audit examination ensures your premium reflects these realities.
Types of Workers Compensation Audits
Insurance carriers typically conduct audits in one of three ways:
- Physical Audits: An auditor visits your business location to review workers compensation records, interview key personnel, and physically verify your operations.
- Telephone Audits: The auditor contacts you by phone and may request documents electronically.
- Mail Audits: You complete a questionnaire and submit documentation voluntarily.
When Does a Workplace Injury Audit Occur?
Audits typically occur within 60 days after your policy expires or is canceled. Interim audits may occur if:
- Your business experiences significant growth
- Multiple workplace injury claims occur
- Misclassification or underreporting is suspected
- Your policy requires periodic verification
What Is a Workers Comp Review?
A workers comp review is a proactive assessment designed to evaluate your workers compensation program before an official audit occurs. It focuses on identifying errors, inefficiencies, and cost-saving opportunities.
Unlike audits, reviews are advisory and help protect your interests as a policyholder.
Components of a Workers Comp Review
- Policy and coverage analysis
- Employee classification review
- Experience Modification Rate (EMR) analysis
- Safety program evaluation
- Claims handling review
