In this qualitative evaluation of 14 U.S. health insurers' coverage policies concerning mifepristone-induced medical abortion, the findings suggest that a significant proportion of health plans do not include evidence-based clinical information obtained from recent research, data, and practice. This omission may hinder the adoption of new, evidence-based protocols for medical abortion by physicians. A model coverage policy that contains comprehensive clinical information regarding appropriate clinical regimens for mifepristone is provided as an example for insurers and others in the field.
