Use CPT 59510 when the following criteria are met:

Included Services

• Routine antepartum care (typically 13 prenatal visits)

Billing Guidelines for CPT 59510

Global Billing Rules

• This is a global maternity care code. It should be billed once per pregnancy when full care is provided.
• Most payers consider the global period to span the entire pregnancy through postpartum.

Payer Considerations

• Verify payer-specific requirements, as some insurers carve out antepartum/postpartum care separately.
• Medicaid plans may have unique billing policies requiring separate codes for prenatal and postpartum services.

Modifier Use for CPT 59510

Modifiers help clarify services when the global package is not fully provided:

Documentation Tips for Accurate Claim Submission

To support CPT 59510, documentation should include:

• Complete prenatal care records (visit dates, assessments, labs, counseling, fetal monitoring)

• Delivery report including:

  • Indication for C-section

  • Procedure details

  • Complications (if any)

Postpartum visit notes

• Patient education and follow-up plan

• Care coordination notes, if transitional care occurred

Clear documentation helps justify global billing and supports payer audits.

Common Examples of CPT 59510 Use

Example 1: Planned C-Section with Full Care

A patient receives all prenatal visits, undergoes a scheduled C-section, and completes all postpartum visits with the same OB/GYN.
→ Bill CPT 59510

Example 2: Emergency C-Section with Global Care

Patient plans for vaginal birth but requires an emergency C-section. The same provider manages prenatal and postpartum care.
→ Bill CPT 59510

Example 3: Transfer of Care Mid-Pregnancy

Patient transfers at 32 weeks to a new provider for C-section and completes postpartum care.
→ The new provider cannot bill CPT 59510. They must bill partial maternity care codes.

Common Mistakes & Claim Denials (and How to Avoid Them)

Summary:

CPT code 59510 is a global maternity care code used when the same provider or practice delivers complete obstetric care for a patient who has a cesarean delivery. It covers routine antepartum care, the C-section procedure, and postpartum care for up to six weeks.

This code should only be billed when full maternity care is provided by one provider or group. If care is shared or transferred, separate maternity care codes must be used. Accurate documentation of prenatal visits, delivery details, and postpartum care is essential. Check payer policies and apply modifiers only when services fall outside the global package.
