Objective: To estimate the maternity-related cost of health care services in women with and without severe maternal morbidity (SMM). Methods: Women with a live inpatient birth in the calendar year 2013 were identified in the MarketScan® Commercial and Medicaid health insurance claims databases. Costs were defined as the amounts paid by insurers plus out-of-pocket and third-party payments. Costs were calculated as total maternity-related costs and categorized as prenatal, delivery, and postpartum costs. SMM was identified using the CDC algorithm of 25 ICD-9 diagnostic and procedural codes. Variables associated with higher delivery costs were determined by multivariable linear regression analysis. Results: A total of 750 women met the criteria for SMM in the Commercial population. The total, per-patient mean costs of care for women without and with SMM were $14,840 and $20,380, respectively. Delivery hospitalization costs were 76-77% of total mean costs for women without and with SMM. A total of 99 women met the criteria for SMM in the Medicaid population. The total, per-patient mean costs of care for women without and with SMM were $6894 and $10,134, respectively. Delivery costs were 71–72% of total costs. Variables independently predictive of increased delivery costs in both Commercial and Medicaid populations were delivery by cesarean section, multifetal gestation, gestational hypertension/preeclampsia, and obstetric infection. Conclusions: The occurrence of SMM was associated with an increase in maternity-related costs of 37% in the Commercial and 47% in the Medicaid population. Some of the factors associated with increased delivery hospitalization costs may be prevented.
