NCCI Class Codes & Rates

The National Council on Compensation Insurance (NCCI) provides class codes and rates to 38 states, including Iowa. NCCI reviews and updates the loss data collected each year and makes recommendations on class code and rate changes to the State of Iowa Insurance Commissioner. Once approved, IMWCA applies those class codes and rates effective the following January 1.

Work Codes & Rates

Each employee’s work may fall into one or more classification (class) codes, and the rate charged for each code is based on the past loss experience for that type of work. The codes and rates IMWCA uses are developed, maintained, and updated by the National Council on Compensation Insurance (NCCI) annually.
