2027 Maternity Billing Changes: New CPT Codes, Eliminated Global Codes & What Providers Need to Know

Effective January 1, 2027, maternity billing is undergoing one of its most significant transformations in decades. Is your practice prepared?

For years, OB/GYN practices, midwives, and maternity healthcare providers have relied on global maternity CPT codes such as 59400, 59510, and 59610 to bill for comprehensive maternity care.

Beginning January 1, 2027, that familiar billing structure is changing.

The American Medical Association (AMA) has officially announced a major restructuring of maternity care coding, replacing traditional global maternity packages with a more detailed approach that separates prenatal care, labor management, delivery, and postpartum services.

The changes affect 35 CPT codes: 17 deletions, 12 additions, and 6 revisions.

For maternity providers, this is much more than a routine annual CPT update. These changes may significantly affect documentation, reimbursement, claims processing, and overall revenue cycle management.

At Modern Medical Billing, we're helping healthcare providers understand what these changes mean and how to prepare before they take effect.

1. Goodbye Global Maternity Codes: What's Changing in 2027?

Under the traditional maternity billing structure, providers could report a single global CPT code covering multiple stages of pregnancy.

For example:

• 59400: Routine obstetric care, including prenatal care, vaginal delivery, and postpartum care.

• 59510: Routine obstetric care, including prenatal care, cesarean delivery, and postpartum care.

• 59610: Routine obstetric care, including prenatal care, vaginal delivery after a previous cesarean, and postpartum care.

  
  

Beginning in 2027, these codes will be eliminated.

Instead, maternity care will be divided into four separately reportable phases:

1. Antepartum care: Prenatal visits reported using appropriate evaluation and management (E/M) codes.

2. Labor management: New CPT codes distinguishing initial and subsequent days of labor and the complexity of management.

3. Delivery: New procedure-specific CPT codes for vaginal and cesarean deliveries.

4. Postpartum care: E/M reporting for qualifying inpatient and outpatient postpartum encounters.

This approach is intended to better represent the actual services provided throughout pregnancy, particularly when multiple physicians, midwives, or healthcare organizations participate in a patient's care.

However, separating maternity services into individual billing components introduces new administrative and documentation responsibilities.

2. Complete List of Deleted Maternity CPT Codes for 2027

The following 17 CPT codes are being deleted effective January 1, 2027.

These deletions mean practices cannot simply continue submitting the same maternity codes for services performed in 2027.

Billing systems, encounter workflows, charge capture processes, and payer-specific billing policies must be reviewed.

3. The 12 New Maternity CPT Codes for 2027

The AMA has introduced 12 new codes covering labor management, delivery, certain repairs, and postpartum procedures.

The new codes distinguish services that previously may have been bundled together or reported through broader delivery codes.

Six existing CPT codes are also being revised

The AMA identifies the following codes as revised for 2027:

59051, 59300, 59412, 59414, 59898, and 59899.

These revisions affect existing obstetric services and associated reporting instructions. Providers should review the final CPT 2027 descriptors and coding guidelines before implementing them.

4. Prenatal Care: Individual E/M Billing Replaces Antepartum Packages

One of the most important changes involves routine prenatal care.

Previously, providers commonly used CPT 59425 or 59426 to report multiple prenatal visits.

Beginning in 2027, prenatal encounters will generally be reported individually using the appropriate E/M code.

This may include office-based E/M codes such as 99212–99215 for established patients, depending on the encounter, medical decision-making, documentation, and applicable coding rules.

For maternity practices, this means:

• Each qualifying prenatal encounter must be documented appropriately.

• The E/M level must reflect the actual services performed.

• Providers must capture encounters accurately rather than relying on bundled prenatal packages.

• Claims must comply with payer-specific requirements.

Important: The number of prenatal visits alone will no longer determine a bundled antepartum CPT code.

This makes consistent documentation and accurate encounter capture especially important.

5. New Labor Management Codes: Straightforward vs. Complex Labor

Another major change is the introduction of four new labor management CPT codes.

These distinguish initial-day and subsequent-day labor management, with separate categories for straightforward and complex care.

Straightforward labor generally involves uncomplicated maternal and fetal conditions, routine monitoring, and normal progression or routine induction.

Complex labor may involve additional maternal or fetal risks, abnormal progression, prior cesarean delivery, or other circumstances requiring increased management.

Labor management is generally reported by calendar date, subject to the new CPT instructions.

A planned cesarean delivery without labor management does not automatically qualify for a separate labor management code.

Providers will need to document the medical circumstances supporting the selected labor management level.

6. Vaginal Delivery Billing Changes

Beginning in 2027, the new vaginal delivery codes are:

59431 — Vaginal delivery

59432 — Vaginal delivery after previous cesarean

These delivery codes include certain routine services associated with the delivery, including delivery of the placenta, routine same-day postpartum care, and qualifying first- or second-degree laceration repairs performed by the delivering provider or group.

Labor management may be separately reported when the applicable requirements are met.

This distinction is important because providers must understand which services are included in the delivery code and which may qualify for additional reporting.

7. Cesarean Delivery Billing Changes

The traditional cesarean global codes will also be eliminated.

The new structure introduces:

59502 — Primary cesarean delivery

59503 — Repeat cesarean delivery

These codes represent the cesarean delivery itself rather than an entire maternity care package.

Where separately reportable labor management occurs before the cesarean, the appropriate labor management code may also apply.

For example, a patient undergoing a scheduled repeat cesarean without labor would generally not have a separate labor management service.

A patient undergoing a trial of labor before ultimately requiring a repeat cesarean may have separately reportable labor management when documentation and coding requirements are satisfied.

8. Third- and Fourth-Degree Laceration Repairs

The 2027 revisions introduce separate reporting for certain significant perineal repairs.

59433 — Third-degree laceration or episiotomy repair

59434 — Fourth-degree laceration or episiotomy repair

These services may be reported separately when performed and properly documented.

First- and second-degree repairs performed by the delivering provider or group remain included in the applicable vaginal delivery code.

This is an important distinction for coding accuracy and preventing inappropriate unbundling.

9. Postpartum Care Will Be Reported Differently

Postpartum care is another major area of change.

Traditional postpartum-only billing code 59430 is being eliminated.

Under the new structure, postpartum encounters will generally be reported using applicable E/M codes.

Routine postpartum care on the calendar day of delivery remains included in the delivery code.

For qualifying subsequent inpatient days, providers may report appropriate hospital E/M services, followed by discharge-day management when applicable.

Outpatient postpartum encounters will be reported using the appropriate office or other outpatient E/M codes.

The new CPT 59623 also allows separate reporting of qualifying uterine tamponade procedures used to manage postpartum hemorrhage.

Practices must carefully distinguish included delivery services from separately reportable postpartum care.

10. What Happens to Pregnancies That Begin in 2026 and End in 2027?

This is one of the most important transition issues.

Consider a patient who begins prenatal care in October 2026 but delivers in February 2027.

That patient's maternity care spans two different CPT coding structures.

Providers must determine how to report services furnished before and after January 1, 2027, while avoiding duplicate billing.

The AMA has issued specific transition guidance addressing prenatal care, deliveries, and postpartum services that cross the implementation date.

Practices should review open maternity episodes, services already billed, expected delivery dates, and individual payer requirements.

Do not assume that a global code can be submitted for a 2027 delivery simply because prenatal care began in 2026.

Transition errors could create preventable denials, payment delays, or incorrect reimbursement.

11. Will These Changes Affect Maternity Reimbursement?

Potentially, yes.

The transition from global maternity billing to phase-specific reporting may change how and when practices receive reimbursement.

Under the traditional structure, a practice might receive a bundled payment covering a substantial portion of maternity care.

Under the revised CPT framework, separate encounters and services can be identified individually.

However, separate CPT reporting does not automatically guarantee separate insurance reimbursement.

Insurance carriers may establish their own payment methodologies, contracted rates, claims-editing rules, and maternity payment policies.

Important considerations include:

• Whether payer contracts reference deleted global CPT codes.

• How new labor and delivery codes will be reimbursed.

• Whether individual prenatal and postpartum encounters will be separately paid.

• How Medicaid and commercial insurance policies will handle maternity care.

• Whether billing changes will affect cash flow and accounts receivable.

• How multiple providers participating in the same pregnancy will be reimbursed.

Practices should not assume their total maternity reimbursement will remain unchanged.

12. Does This Mean All Global Surgical Codes Are Being Eliminated?

No.

The 2027 maternity restructuring specifically eliminates traditional global maternity CPT packages.

It does not automatically eliminate the global surgical periods used for other procedures.

Other surgical services may continue to have applicable 0-day, 10-day, or 90-day global periods under Medicare or individual payer policies.

The AMA has also announced additional 2027 CPT changes involving several surgical specialties, including hernia repair, ventricular assist devices, and prostate biopsy procedures.

These are separate coding updates and should not be confused with the elimination of global maternity packages.

13. What Should OB/GYN Practices, Midwives, and Birthing Centers Do Before January 2027?

Preparation should begin before the new codes become effective.

Review your existing maternity claims. Identify the global maternity codes your practice currently uses and determine which services will require a different reporting approach.

Update billing software and coding workflows. Ensure new CPT codes, encounter types, and claim edits are ready for 2027 dates of service.

Evaluate clinical documentation. Confirm that providers understand the documentation needed for prenatal E/M encounters, labor complexity, delivery procedures, and postpartum care.

Review insurance contracts and fee schedules. Determine how commercial insurance carriers, Medicaid programs, and other payers intend to reimburse services under the new structure.

Identify patients whose care spans both years. Create a transition plan for pregnancies beginning in 2026 with expected deliveries in 2027.

Train your billing team. Staff should understand the new codes, included services, modifier requirements, and payer-specific billing instructions.

Monitor reimbursement and denials. Track collections, claim rejections, and payment trends during the first months of implementation.

14. How Modern Medical Billing Can Help Your Practice Prepare

At Modern Medical Billing, we understand that maternity billing involves much more than submitting claims.

From prenatal visits and labor management to delivery procedures and postpartum care, accurate billing requires specialty-specific knowledge, detailed documentation, and careful insurance coordination.

With major CPT changes approaching, practices need more than updated code lists. They need a revenue cycle strategy that protects their financial operations during the transition.

Our team can assist with maternity billing reviews, coding workflow preparation, insurance verification, reimbursement analysis, claims management, denial follow-up, and ongoing revenue cycle support.

Whether you operate an OB/GYN practice, midwifery practice, or birthing center, preparing now can help reduce avoidable billing disruptions in 2027.
