Class Code aka Governing Class Code
The governing code, as defined in the National Council on Compensation Insurance (NCCI) Basic Manual for Workers Compensation and Employers Liability Insurance (Basic Manual) Rule 1-B-5, is the basic classification at a specific job or location (other than a standard exception code) that produces the greatest amount of payroll. If a change to a policyholder’s governing class code occurs (as documented on an NCCI Inspection & Classification Report), then the governing code is considered reclassified.
