The only way students may opt-out of USF's plan is to prove "that they have coverage comparable (equal or better) to the University-sponsored plan". Otherwise, "Students automatically will be enrolled in, and have their accounts billed for, the University-sponsored Student Health Insurance Plan."
According to the plan brochure:
The University of San Francisco Student Health Insurance Plan has been developed especially for eligible University of San Francisco students and their eligible dependents. The Plan provides coverage for illnesses and Injuries that occur on and off campus, and includes special cost-saving features to keep coverage as affordable as possible. University of San Francisco is pleased to offer the Plan, as described in this Brochure, to students and their eligible dependents.
The specially developed plan, which is available as a pdf at both USF's and Aetna's website includes the following coverage under the heading of "Maternity Expenses":
"Voluntary Termination of Pregnancy - Covered Medical Expenses are payable as follows:
Preferred Care: 90% of the Negotiated Charge.
Non-Preferred Care: 70% of the Reasonable Charge."
Employers are not required to provide abortion coverage in California. Other Catholic institutions in San Francisco which offer health insurance, including the Archdiocese of San Francisco, do not provide abortion coverage.
Unless USF's website is grossly incorrect, it would seem that the institution "Educating Minds and Hearts to Change the World" forces those minds and hearts to fund "an unspeakable crime". (Gaudium et Spes)
