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.
