The proposed rule amendment deletes discontinued class codes, adds new class codes and revises descriptions of class codes, as published in the Florida exception pages in the National Council on Compensation Insurance, Inc. (NCCI), Basic Manual (January 2010 edition). In addition, the amendment defines when an employer is engaged in the construction industry, for purposes of the rule. As class codes are revised, added or deleted in the Basic Manual, the rule must be amended to accurately reflect and incorporate such changes.
