Wis. Admin. Code § ETF 40.10
(1) An employee of an employer, other than the state, shall be eligible for health insurance under s. 40.51 (7), Stats., if requirements of ss. 40.02 (46) and 40.22, Stats., or of s. 40.19 (4) (a), Stats., are satisfied. An employee of an employer that is not a participating employer shall be eligible for health insurance under s. 40.51 (7), Stats., if the requirements set forth in s. 40.02 (28) are satisfied and the following requirements are met:
(2) As provided in a collective bargaining agreement under subch. IV of ch. 111, the employer, including an employer that is not a participating employer, shall pay an employer contribution toward the gross health insurance premium based on the lowest cost qualified plan in the service area of the employer, as follows:
(d) The 105%-of-cost limitation in par. (b) does not apply to an employer that establishes an arrangement for contributing towards the premiums for employee health insurance under s. 40.51 (7), Stats., under which all of the following apply:
4. The employer contribution towards the premium of each qualified plan in the service area of the employer shall be an amount at least equal to the applicable minimum contribution under par. (a), (b) or (c). The employer contribution is determined by subtracting the employee contribution amount for the plans in that tier from the total plan premium for the type of coverage.
Example. Assume there are only two qualified plans in the service area of the employer. One plan is a Tier 1 plan, the other is a Tier 2 plan, and the single and family premiums are shown in the following table:
Under the tiered arrangement, a full-time employee’s premium payment for Plan A (and all Tier 1 plans that might be available, but not qualified) may be between $0 and a maximum of $190 for single coverage, depending on whether the employer is contributing the minimum amount allowed, or more. The employer must contribute no less than $200 towards single coverage, but under these circumstances must contribute at least $210 towards single coverage premium for Tier 1 plans, because that is the lowest amount that is at least equal to one-half of the lowest cost plan and also sufficient to assure both 1) that the employee contribution for single coverage under the Tier 2 plan will be at least $20 higher than the Tier 1 amount and 2) that the remainder, paid by the employer, will be at least $200. The employer contribution towards family coverage must be at least $450. This is one-half of the lowest cost plan premium for family coverage and is also sufficient to assure that the difference between the employee premiums for the Tier 1 and Tier 2 coverage is at least $50.
(3) Except as provided under sub. (2), the employer shall pay an employer contribution toward the gross health insurance premium based on the average premium of qualified plans in the service area of the employer, as follows:
