Global Maternity Billing vs. Split Care: Key Differences for OB/GYN Practices

Maternity billing becomes more complicated when one OB/GYN practice does not provide every stage of pregnancy. Understanding global maternity billing and split care helps practices select appropriate codes, document services, and reduce claim problems.

For 2026 dates of service, legacy maternity codes remain relevant. The CPT maternity care structure changes January 1, 2027, when current global maternity codes are deleted and maternity care is reported in separate phases.

What Is Global Maternity Billing?

Global maternity billing generally applies when the same physician or group provides the routine antepartum care, delivery, and postpartum care covered by the applicable global maternity code.

For example, CPT 59400 represents routine obstetric care including antepartum care, vaginal delivery, and postpartum care. CPT 59510 represents routine obstetric care including antepartum care, cesarean delivery, and postpartum care.

Global billing is based on the care actually provided. A practice should not report a complete global maternity code when another provider handled part of the maternity episode.

Global billing can simplify reporting when one practice manages the full episode, but documentation remains important.

What Is Split Care?

Split care occurs when different physicians or groups provide different portions of maternity care. This can happen because of transfer, insurance change, relocation, referral, or provider availability.

For example, one OB/GYN may provide prenatal care until 34 weeks while another physician takes over delivery and postpartum care. Neither practice should automatically report the complete global package.

Each provider generally reports the portion of care actually delivered under applicable coding rules and payer requirements.

Global Maternity Billing vs. Split Care

To distinguish them, identify who provided each stage of pregnancy.

Global maternity billing

• One physician or group provides the complete routine maternity episode.

• Antepartum, delivery, and postpartum care are included in the applicable global code.

• The practice reports the appropriate global maternity CPT code when requirements are met.

Split care

• Two or more providers participate in different stages.

• Each provider reports the portion of care it actually delivered.

• Component or individual service codes may be appropriate.

• Documentation should establish the transfer point and services performed.

Selecting a global code when care was split can lead to claim edits or denials.

Common Maternity CPT Codes for 2026

For 2026 dates of service, several maternity codes are important.

CPT 59400 covers antepartum care, vaginal delivery, and postpartum care. CPT 59409 covers vaginal delivery only, while CPT 59410 covers vaginal delivery and postpartum care.

For antepartum-only care, CPT 59425 applies to four through six visits, and CPT 59426 applies to seven or more visits. CPT 59430 represents postpartum care only.

For cesarean maternity care, CPT 59510 represents routine obstetric care including antepartum care, cesarean delivery, and postpartum care.

Code selection depends on services provided, provider participation, transfer circumstances, documentation, and payer requirements.

How Transfer of Care Changes Billing

Transfer of care requires careful review. Determine when the original provider stopped managing the pregnancy and what the receiving provider performed.

Consider a patient who receives prenatal care from Practice A until 30 weeks and then transfers to Practice B. Practice A did not provide the complete maternity episode, so a full global code would generally not represent the care provided. Practice B must also determine which components it performed before selecting its codes.

Documentation should support:

• The date or stage of transfer.

• Number of antepartum visits provided.

• Whether delivery was performed.

• Whether postpartum care was provided.

• Any separately reportable services.

• Relevant payer instructions.

Review the medical record and payer requirements before finalizing the claim.

Insurance Changes and Split Maternity Care

A change in insurance during pregnancy can create another billing complication. The payer may have specific requirements before and after the coverage change.

Billing staff should verify eligibility and benefits, identify the applicable payer, and determine whether it recognizes global maternity billing.

This is especially important when a claim crosses coverage periods.

Documentation Requirements

Strong documentation is essential for global and split maternity billing. The record should identify what services were provided and by whom.

Documentation should support:

• Antepartum care and number of visits.

• Delivery type and provider involvement.

• Postpartum services.

• Transfer or termination of care, when applicable.

• Complications requiring additional management.

• Relevant gestational information.

• Services separately reported from routine maternity care.

Consistent documentation helps coders determine the appropriate reporting method.

Common Billing Mistakes

Common mistakes include:

• Billing a full global code after a transfer of care.

• Selecting an antepartum-only code without confirming visit count.

• Reporting delivery-only services when postpartum care was also provided.

• Using incomplete transfer documentation.

• Reporting incorrect dates of service.

• Assuming every pregnancy-related service is included in the global package.

• Applying modifiers without confirming that they are appropriate.

• Failing to review payer-specific maternity policies.

Review the complete maternity timeline before claim submission.

How Global Maternity Billing Services Can Support Accuracy

Global Maternity billing services can support a consistent review process for maternity claims, including coding, documentation, eligibility, payer requirements, and claim review.

A useful pre-billing checklist asks:

• Did our practice provide the complete maternity episode?

• Was care transferred?

• How many antepartum visits were provided?

• Who performed the delivery?

• Who provided postpartum care?

• Does the CPT code match those services?

• Are payer-specific requirements satisfied?

Preparing for 2027 Maternity Coding Changes

Practices should prepare for a major CPT change beginning January 1, 2027. The AMA has announced that current global maternity codes will be deleted and replaced with separate reporting for antepartum care, labor management, delivery, and postpartum care.

Under the new structure, antepartum and postpartum services will generally use appropriate E/M codes, while new codes address labor management and delivery.

Do not apply 2027 rules to 2026 claims. Practices can review EHR templates, payer policies, workflows, and staff education before the transition.

FAQs

Can an OB/GYN bill global maternity care after a transfer?

Generally, a complete global code should not be reported when the practice did not provide the full maternity episode. Reporting depends on services actually provided and payer rules.

What is the difference between 59409 and 59410?

For 2026, CPT 59409 represents vaginal delivery only, while CPT 59410 represents vaginal delivery with postpartum care. Always verify current CPT and payer guidance.

Can insurance changes affect global maternity billing?

Yes. A coverage change can affect how services are reported and submitted. Eligibility, benefits, payer policies, and dates of service should be reviewed before claims are finalized.

Conclusion

Global maternity billing and split care are not interchangeable. The correct approach depends on who provided antepartum, delivery, and postpartum services and applicable payer rules. Reviewing the maternity timeline and documentation can prevent many avoidable billing errors.

For 2026 claims, practices should continue following the applicable maternity coding structure. With CPT changes scheduled for 2027, practices should prepare their teams and workflows.
