How is CPT Code 59400 Reimbursed in the USA?

CPT Code 59400 is reimbursed in the USA under maternity care guidelines, providing a bundled payment for routine antepartum care, vaginal delivery, and postpartum visits. Reimbursement rates vary, with Medicare averaging around $3,000–$3,400 per case, while commercial payers often pay 15–25% more based on contracts. Accurate billing under this code helps practices secure predictable revenue and reduce claim rework tied to maternity care.

• Average national Medicare reimbursement: ~$3,000–$3,400 per obstetric care episode
• Commercial payers often reimburse 15–25% higher depending on the plan and network agreements

   

• Medicaid reimbursement for 59400 varies by state, often ranging from $1,800–$2,400
• Under CMS guidelines, this code falls under maternity care policy, meaning:
• It covers routine care only, excluding high-risk or unrelated E/M services.
• Non-routine visits require separate billing with modifier 25 on E/M codes.
• The global period for maternity care typically includes the entire pregnancy through postpartum care (up to 6 weeks post-delivery).

How Does the Period Work for CPT 59400?

The global period for CPT 59400 typically includes the entire pregnancy through 42 days postpartum, covering all routine antepartum visits, vaginal delivery, and postpartum care in a single bundled payment. Under CMS guidelines, this means related services during this period are not billed separately unless unrelated to pregnancy and supported with documentation. Understanding this global period helps your practice prevent denials while ensuring compliant, complete reimbursement for maternity care. Under USA laws and CMS global maternity guidelines:

• Global period for maternity care: 42 days postpartum
• All routine care, delivery, and postpartum visits are bundled under 59400.
• Services outside routine care (e.g., chronic hypertension management, unrelated infections) can be billed separately with documentation and appropriate modifiers.

How Using 59400 CPT Code Correctly Can Reduce Denials

Using 59400 CPT code correctly can significantly reduce denials by ensuring you bill only when your practice provides all routine antepartum care, vaginal delivery, and postpartum visits as required. It prevents common errors like billing for incomplete care under global codes or missing necessary modifiers for unrelated services during the global period. Accurate use of 59400 supports clean claims, faster payments, and a stronger OB/GYN revenue cycle. Denials often occur when:

• Providers bill 59400 but the patient transfers care mid-pregnancy
• Documentation does not support the delivery performed by the billing provider
• Services unrelated to pregnancy are incorrectly bundled

To avoid denials:

• Verify payer guidelines for 59400 usage.
• Ensure accurate documentation of start and end dates of care.
• Use split billing codes if you did not provide full global care.
