(a) The monthly contribution of each eligible employee for health benefit plan coverage under this act shall be the total cost per month of the benefit coverage afforded under the plan or plans, for which the employee exercises the option, including the administrative expenses therefor less the portion thereof contributed by the employer. An employee may enroll in more than one option at a time so long as such options do not offer overlapping services.

(b) The employer contribution shall be the amount necessary to pay the cost of the health benefit plan covering the employer’s covered employees for which the employer does not require the employee to pay, including the administrative expenses therefor. An employer is not required to enroll an employee who is already enrolled in a health benefit plan other than the small employer health benefit plan.

(c) Payroll deductions for such costs payable by the employee shall be made by the employer upon receipt of a signed authorization from the employee indicating an election to participate in the small employer health benefit plan.
