No long-term care insurance policy or certificate other than a policy or certificate thereunder issued to a group as defined in subdivision 58-17B-2(4)(a):
The director may extend the limitation periods set forth herein as to specific age group categories in specific policy forms upon findings that the extension is in the best interest of the public. The definition of "preexisting condition" does not prohibit an insurer from using an application form designed to elicit the complete health history of an applicant, and, on the basis of the answers on that application, from underwriting in accordance with that insurer's established underwriting standards. Unless otherwise provided in the policy or certificate, a preexisting condition, regardless of whether it is disclosed on the application, need not be covered until the waiting period described in subdivision (2) of this section expires. No long-term care insurance policy or certificates may exclude or use waivers or riders of any kind to exclude, limit or reduce coverage or benefits for specifically named or described preexisting diseases or physical conditions beyond the waiting period described in subdivision (2) of this section.
