044-34 Wyo. Code R. § 2
No cancer policy filed with the Department of Insurance subsequent to the effective date of these rules, be it an expense reimbursement or stated benefit policy, shall be approved for use in the State of Wyoming unless proper and adequate certification is submitted along with the policy filed showing that benefits in relation to the premium charged are designed to produce a minimum loss ratio of not less than sixty (60) percent over a given year period of time. Such certifications shall be made annually thereafter in accordance with the provisions of Section 1 of this Part. If subsequent to the approval of a cancer policy, such certification shows in any year for which it was filed that the policy has produced or will produce less than a sixty (60) percent loss ratio over a five year period of time, it may be withdrawn and refiled in accordance with the provisions of Section 1 of this Part.
