Application of the KE and KY modifiers is dependent upon the bid status of the accessory and the base piece of equipment. Please note: This tool strictly provides information on whether the KE, KY, or KE and KY modifier combinations are required. Other modifiers may be required in addition to the KE and/or KY modifier.
