Medicaid Cost Savings from Provision of Contraception to Beneficiaries in South Carolina, 2012-2018.

This study assesses cost savings associated with specific contraceptive methods provided to beneficiaries enrolled in South Carolina Medicaid between 2012 and 2018. Incremental cost-effectiveness ratios, defined as the additional cost of contraception provision per live birth averted, were estimated for 4 contraceptive methods (intrauterine devices [IUDs], implants, injectable contraceptives, and pills), relative to no prescription method provision, and savings per dollar spent on method provision were calculated. Costs associated with publicly funded live births were derived from published sources. The analysis was conducted for the entire Medicaid sample and separately for individuals enrolled under low-income families (LIFs), family planning, and partners for healthy children (PHC) eligibility programs. Sensitivity analysis was performed on contraceptive method costs. IUDs and implants were the most cost-effective with cost savings of up to $14.4 and $7.2 for every dollar spent in method provision, respectively. Injectable contraceptives and pills each yielded up to $4.8 per dollar spent. However, IUDs and implants were less cost-effective than injectable contraceptives and pills if the average length of use was less than 2 years. Medicaid's savings varied across Medicaid eligibility programs, with the highest and lowest savings from contraceptive provision to women in the LIFs and PHC eligibility programs, respectively. The results suggest the need to account for unique needs and preferences of beneficiaries in different Medicaid eligibility categories during contraception provision. The findings also inform program administration and provide evidence to justify legislative appropriations for Medicaid reproductive health care services.
