Experience Modification Rate (EMR) Audit

What Is an Experience Modification Rate and Why Does It Matter?

Your Experience Modification Rate (EMR, also called the “experience mod” or “mod factor”) is one of the most important numbers in your business's insurance cost structure. Calculated by the National Council on Compensation Insurance (NCCI), your EMR compares your actual workers' comp claims history against what is statistically expected for businesses of your size and industry classification.

The EMR is applied as a direct multiplier to your workers' compensation premium. A business with an EMR of 1.0 pays the standard rate. A business with an EMR of 1.5 pays 50% more than standard. A business with an EMR of 0.85 pays 15% less than standard.

For many New York businesses, the difference between an accurate EMR and an inflated one can be thousands or tens of thousands of dollars per year in unnecessary premium charges — charges that compound over time and are completely avoidable.

Common EMR Calculation Errors

EMR errors occur more frequently than most business owners realize. The NCCI calculates your EMR based on data reported by your insurance carrier, and errors in carrier reporting translate directly into errors in your mod:

• Incorrect claim values: Claims may be reported at values higher than actual paid amounts, especially if reserves were set high and not subsequently reduced.
• Subrogation recoveries not credited: When a third party is responsible for an injury and the insurer recovers money, that recovery must reduce the claim value in the EMR calculation.
• Medical-only claims improperly included: Small medical-only claims (under certain thresholds) receive a discount in EMR calculations. When incorrectly coded as lost-time claims, they inflate your mod.
• Claims from prior employer included: If you acquired a business, claims from the prior business should not be attributed to your EMR in most circumstances.
• Wrong classification codes: If employees are classified under the wrong NCCI code, the “expected” claims figure used in your mod calculation will be wrong.
• Data entry errors: Simple transcription errors in payroll figures or claim amounts are surprisingly common.
• Policy consolidation issues: Businesses with multiple policies may have claims incorrectly aggregated.

The EMR Audit Process

Our EMR audit is systematic and thorough:

1. Unit statistical report review: We obtain and analyze your unit statistical reports from NCCI, which contain the underlying claims data used to calculate your EMR.
2. Claims history comparison: We compare the reported claims to your actual claims data from your insurer, looking for discrepancies in values, types, and attribution.
3. Classification code verification: We verify that all employees are classified under the correct NCCI codes for their actual job duties.
4. Reserve analysis: We review open claim reserves to identify cases where inflated reserves are harming your current mod.
5. Correction filing: Where errors are identified, we file formal corrections with NCCI and your insurer and follow through to ensure they are processed.
6. Retroactive premium recovery: Confirmed errors entitle you to retroactive premium adjustments for prior policy years, and we pursue these recoveries aggressively.

EMR and WCB Penalties: The Connection

There is an important connection between EMR management and WCB penalties. Businesses facing WCB penalties for coverage lapses often also have elevated EMRs from the incidents that led to the penalty investigation. By addressing both issues simultaneously, we can often achieve more favorable outcomes on both fronts.

Additionally, businesses with high EMRs may find it difficult to obtain affordable workers' comp coverage — which can create a cycle where expensive or difficult-to-obtain coverage leads to lapses, which leads to WCB penalties. Correcting your EMR is often a prerequisite to obtaining favorable coverage going forward.

EMR Impact on Government Contracts

Many New York government contracts and project labor agreements have EMR thresholds — commonly requiring an EMR below 1.0 or 1.2 as a condition of bidding. If your EMR exceeds these thresholds due to calculation errors rather than actual claims experience, you may be losing contracts you should be winning. Correcting an inflated EMR can immediately restore your eligibility for lucrative government work.

Typical Results

Our EMR audits regularly produce significant savings:

• EMR reductions of 0.05–0.25 points are common
• Premium savings of $5,000–$50,000+ per year for mid-size businesses
• Retroactive refunds for 1–3 prior policy years
• Restored eligibility for government contract bidding
