Idaho Code § 32-1214D

The plan administrator or employer shall enroll the child unless the employer or insurer does not offer insurance, the obligor would not qualify for any plan, or the obligor has separated from employment. If insurance is not available because a probationary period exceeds ninety (90) days, the plan administrator or employer shall return the notice to the employer and the department without enrolling the child. If insurance is not available during a probationary period that is ninety (90) days or less, or if ninety (90) days or less remains from a longer waiting period, the plan administrator shall process the enrollment, and notify the employer, the department or other obligee, of the effective date of coverage.
