Workers' Comp Codes and NCCI Classification

A class code is a three or four digit numerical code assigned by NCCI or a State Rating Bureau such as California's WCIRB. Class codes are assigned to differentiate between the various job duties or scope of work performed by employees. NCCI's classification system contains nearly 800 unique class codes and is the basis for both pricing and underwriting workers' compensation insurance rates. NCCI is the abbreviation for the National Council on Compensation Insurance. They provide statistical data to insurance companies and states.

Workers' Comp Codes Affect Rates and Pricing

One of the primary means of pricing workers' compensation insurance is classifying a risk, or workplace exposure, within the proper NCCI workers' compensation class code. Incorrect risk classifications by insurance agents or underwriters will result in an inaccurate premium. Payroll may be reclassified and moved to the correct class code at the time of audit. This could result in a policy credit or debit. A workers' compensation audit is the process to make sure payroll was appropriately estimated and employees were correctly classified.

What is NCCI?

In most states, the workers compensation classification system used is maintained by NCCI, the National Council on Compensation Insurance. NCCI is an independent advisory organization largely funded by the insurance companies. Both insurance companies and states utilize NCCI's statistical data for rating and pricing coverage. NCCI's function is to develop and provide the statistical data used to set manual rates for workers compensation insurance. This process is done, individually, for each state that utilizes NCCI. These manual rates are used for pricing and to assign each employers' annual Experience Modification Rate, These NCCI worksheets, or Experience Modification Ratings are developed based on a ratio of claims frequency and cost of premium paid.

NCCI was found in 1923. They help cultivate a healthy workers compensation system. Their objective data and trend analysis promotes competition between insurance companies. Their data is also used by states and insurance companies to set rates for each class code based on prior underwriting profitability or losses.

NCCI Scopes and Workers' Comp Classifications

Each classification code is comprised of a group of employers with a similar exposures, or types of hazards. A basic classification code denotes a particular type of job duty within a business. Therefore, a class code is the systematic arranging of properties, persons, or business operations into groups or categories according to certain criteria. This arrangement is done to create a basis for establishing statistical experience and determining workers compensation rates, and to avoid unfair discrimination by insurance companies. The essential concept of "fair discrimination" is that each risk should bear its fair share of the overall cost of expenses and losses in relationship to its own relevant expenses and hazards.

A Scopes class code is the identifying number for each occupational classification. It is the numeric code assigned to a specific occupation of workers. The class code is based on the nature of the work for the employer and employee. It is common for most employers to have two or more class codes on their policy.

For example: Class code 8810 is for a clerical exposure and class code 5645 is for a general residential construction exposure. A contractor might have laborers working under class code 5645 and an office person rated under the clerical class code.

Classification Codes and Statistical Codes for Workers Compensation and Employers Liability Insurance (Scopes Manual)

The Scopes Manual is the industry standard workers compensation class code book containing numerical classification codes and the classification phraseology for each code used in classifying workers' compensation risks, including state special codes. The NCCI Scopes Manual is available for purchase from NCCI.

Why You Want to Correctly Classify Employees for Workers Comp?

If your business has ever been through a worker comp audit, then you know that the auditor is trying to determine if all payroll is accounted for and if it was assigned to the proper workers' comp code or codes. If an auditor determines that employees were incorrectly classified, the insurance company can retroactively bill your business for up to 3 years of misclassified premium.

Incorrect workers' comp codes can also adversely affect a businesses experience modification factor over time. Claim frequency and loss ratios may be skewed from the industry norm and your business may end up with a higher experience modifier, or EMR rating. This ultimately increases the cost of workers comp insurance.

Some insurance companies may even cancel coverage when a business is found to have incorrect class codes. Anytime a carrier cancels coverage it gets reported to NCCI. Many carriers won't offer workers comp quotes to a business that has had a policy canceled by another carrier.

Which States Do Not Utilize NCCI Class Codes?

There are a few states that do not use the NCCI classification system. California, New Jersey, New York, Delaware, and Pennsylvania utilize their own classification systems. Many other states have some "state special" classifications that may vary significantly from NCCI standard definitions for certain workplace classification codes. To learn more about class codes under NCCI's jurisdiction visit our state workers compensation directory.

Assigning the Right Class Codes to Employee Job Duties

Our Workers Compensation Specialists take the time to review your current work comp class codes in order to make sure we quote your employees and policy correctly. We work directly with NCCI to validate your job classifications and have been successful in recovering past premium from insurance companies who have incorrectly classified your business. Most states allow us to recoup up to three years of premium.

As an employer, you have the right to appeal to NCCI for proper classification assignment. This process may include submitting all job duties to NCCI and paying for an NCCI auditor to come to your facility for an inspection and ruling. In most cases, our Specialists can work with NCCI representatives on your behalf to ensure your employees are properly classified with the classification codes that accurately reflect the scope of work performed and reduce your rates and premium.
