What are the essential billing rules for OB/GYN practices and global maternity care in Texas?
Obstetric billing in Texas is structured around global maternity package codes (CPT 59400 for vaginal delivery, CPT 59510 for cesarean delivery), which encompass routine antepartum care (typically 13 visits), delivery, and 6 to 8 weeks of standard postpartum care. If a patient changes insurance plans during pregnancy, moves away, or delivers with a different medical group, the global package must be split: antepartum care billed via itemized E/M codes or CPT 59425 (4-6 visits) / CPT 59426 (7+ visits), delivery only (59409/59514), and postpartum care only (59430). Texas officially expanded Medicaid postpartum coverage to a full 12 months after delivery under Texas House Bill 12, ensuring extended reimbursement for postpartum depression screenings and chronic condition management.
1. Navigating the Global Obstetric Package in Texas
The global maternity code assumes an uncomplicated pregnancy with longitudinal care provided by a single medical entity.
In metropolitan areas like Dallas and Houston, patients frequently change employer-sponsored insurance plans mid-pregnancy. Billing the global code when another payer was active during the first trimester results in immediate claim rejection and delayed cash flow.
2. The Impact of Texas House Bill 12 (12-Month Postpartum Medicaid)
Unlocking longitudinal postpartum care for Texas mothers
Previously, Texas pregnancy Medicaid coverage ended 60 days postpartum. Under HB 12 enacted by the Texas Legislature, postpartum mothers retain full Texas Medicaid healthcare benefits for 12 full months.
This historic reform allows OB/GYN clinics to provide comprehensive postpartum follow-up, cardiovascular risk assessments, contraceptive management, and mental health screenings without fear of uncompensated care.
