It is an unfair practice for an insurer, and a prohibited practice for a health care service contractor or a health maintenance organization, to fail to respond promptly to any inquiry from the insurance commissioner relative to the business of insurance. A lack of response within fifteen business days from receipt of an inquiry will be considered untimely. A response must be in writing, unless otherwise indicated in the inquiry.
