Objective: To compare patterns of routine postpartum health care utilization for women in Wisconsin with continuous Medicaid eligibility versus pregnancy-only Medicaid METHODS: This analysis used Medicaid records and linked infant birth certificates for Medicaid paid births in Wisconsin during 2011-2015 (n = 105,718). We determined if women had continuous or pregnancy-only eligibility from the Medicaid eligibility file. We used a standard list of billing codes to identify if women received routine postpartum care. We examined maternal characteristics and receipt of postpartum care overall and by Medicaid eligibility category. Finally, we used a binomial model to calculate the relationship between Medicaid eligibility category and receipt of postpartum care, adjusted for maternal characteristics.
Results: Women with continuous Medicaid had profiles more consistent with low postpartum visit attendance rates (e.g., younger, more likely to use tobacco) than women with pregnancy-only Medicaid. However, after adjusting for maternal characteristics, women with continuous Medicaid eligibility had a postpartum visit rate that was 6 percentage points higher than the rate for women with pregnancy-only Medicaid (RD: 6.27, 95% CI 5.72, 6.82).
Conclusions for practice: Women with pregnancy-only Medicaid were less likely to have received routine postpartum care than women with continuous Medicaid. Medicaid coverage beyond the current guaranteed 60 days postpartum could help provide more women access to postpartum care.
