Section 48.83.040 - Preexisting conditions(1) A long-term care insurance policy or certificate may not define "preexisting condition" more restrictively than as a condition for which medical advice or treatment was recommended by or received from a provider of health care services, within six months preceding the effective date of coverage of an insured person, unless the policy or certificate applies to group long-term care insurance under RCW 48.83.020(6) (a), (b), or (c).(2) A long-term care insurance policy or certificate may not exclude coverage for a loss or confinement that is the result of a preexisting condition unless the loss or confinement begins within six months following the effective date of coverage of an insured person, unless the policy or certificate applies to a group as defined in RCW 48.83.020(6)(a).(3) The commissioner may extend the limitation periods for specific age group categories in specific policy forms upon finding that the extension is in the best interest of the public.(4) An issuer may use an application form designed to elicit the complete health history of an applicant and underwrite in accordance with that issuer's established underwriting standards, based on the answers on that application. Unless otherwise provided in the policy or certificate and regardless of whether it is disclosed on the application, a preexisting condition need not be covered until the waiting period expires.(5) A long-term care insurance policy or certificate may not exclude or use waivers or riders to exclude, limit, or reduce coverage or benefits for specifically named or described preexisting diseases or physical conditions beyond the waiting period.
