8 V.S.A. § 4052
(a) Blanket health insurance is a form of health insurance that, to the extent permitted under federal law, is supplemental to major medical health insurance or provides coverage other than the payment of all or a portion of the cost of health care services or products, and that covers special groups of persons as follows:
(b) (1) No blanket health insurance policy shall contain any provision relating to notice of claim, proofs of loss, time of payment of claims, or time within which legal action must be brought upon the policy that, in the opinion of the Commissioner, is less favorable to the persons insured than would be permitted by the provisions set forth in section 4029 of this title.
