(1) In the case of cost-of-illness insurance of an insured person entitled to a sickness allowance in accordance with the principles of the public service, the contracting parties may agree that the insurance will expire to the extent of the increase in the allowance assessment rate when the insured person retires.
(2) If, in the case of an insured person entitled to a sickness allowance in accordance with the principles of the public service, the allowance assessment rate changes, or the entitlement to a sickness allowance lapses, the policyholder is entitled to demand that the insurer adjust the insurance cover within the framework of the existing cost-of-illness insurance tariffs so as to balance out the amended allowance assessment rate, or the discontinued entitlement to allowance. If the application is made within six months after the change, the insurer grants the amended insurance cover without a risk assessment or qualifying periods.
(3) Subsection (2) does not apply to granting insurance at the basic tariff.
