Objective: To report on a one-year experience participating in a capitated healthcare plan for infertility. esign: Prospective study. Setting: University population. Patient(s): Reproductive-age women 15 to 50 years. Intervention(s): The first-generation Lewin infertility algorithm and CATHI software were used to negotiate infertility services under a capitated arrangement for $0.50 per member per month. The following reports our experience for the fiscal year 1997. Main Outcome Measure(s): Infertility services rendered, pregnancy rate, cost of services, collection rates. Result(s): Five thousand forty-six women representing 39,689 member months generated 39 new and 198 return visits. Thirty-two percent of the patients required three visits or less; six patients generated 22% of the visits. Fifty-one percent listed infertility as one of their chief complaints; 31% had mixed diagnoses. Eight (7.6%) patients required surgery, 11 (10.5%) patients underwent either IVF or GIFT cycles. Total charges submitted were $176,636; the amount assigned to specialty care was $135,277, and to IVF/GIFT, $33,433. Total capitated payments, including copayments, was $126,256 under the reproductive medicine agreement and $32,891 under the infertility rider. This resulted in a 71% gross collections rate. Conclusion(s): This study indicates that entering into a capitated health care plan to provide an infertility benefit can produce a successful result.
