CPT® 2027 Maternity Coding Overhaul: What OB/GYN Practices Must Change Before January 1, 2027

Effective January 1, 2027, traditional global maternity codes will be deleted and replaced with phase-specific reporting for antepartum care, delivery, labor management, and postpartum care. This new framework separates pregnancy care into four categories. OB/GYN practices will need to adopt per-encounter E/M reporting, daily labor-management codes, stand-alone delivery codes, and updated documentation and claim-editing processes.

Practices that are not prepared, particularly for pregnancies spanning 2026 and 2027—may face missed charges, claim denials, and cash-flow disruption. This guide explains the new CPT® framework and the operational steps providers, coders, and billing teams should complete before implementation.

What’s Changing with Obstetric Billing Codes in 2027?

Effective January 1, 2027, the maternity care code set will have

• 35 total CPT® code changes
• Including 17 deleted codes
• 12 new codes, and 6 revised codes.

CPT® 2027 Code Changes at a Glance

Effective January 1, 2027, the maternity care code set will undergo 35 total CPT® code changes, including 17 deleted codes, 12 new codes, and 6 revised codes. These updates are designed to modernize maternity care reporting, improve coding accuracy, and ensure providers can document and bill for services that more accurately reflect today's obstetric care.

New Phase-Based Maternity Coding Framework

CPT® 2027 breaks obstetric services into different stages of treatment, rather than using a one-size-fits-all approach for a global maternity package. Antepartum care, labor management, delivery and postpartum care will be reported with individual codes and will be documented and reported differently by providers. This staged pathway more accurately reflects collaborative care models, facilitates more accurate reporting and aligns reimbursement with the specific services provided during a patient's pregnancy. 

CMS Reimbursement and RVU Implementation Timeline

To support these coding changes, the AMA/Specialty Society RVS Update Committee (RUC) has submitted recommendations for valuing the new maternity care codes to the Centers for Medicare & Medicaid Services (CMS). CMS will determine the final Relative Value Units (RVUs) through the annual Medicare Physician Fee Schedule rulemaking process before the new codes take effect. The finalized reimbursement values are expected before implementation, with the updated coding and payment structure becoming effective on January 1, 2027.

How the CPT® 2027 Maternity Care Billing Framework Is Structured?

A total of 35 CPT codes are affected by the update: 17 codes are being deleted, 12 new codes are being introduced, and 6 existing codes are being revised. In place of the traditional global maternity code, obstetric care will now be reported across four distinct phases, each with its own codes, documentation requirements, and reimbursement rules.

Antepartum Care: Billed Per Encounter

The new structure includes reporting antepartum (prenatal) care by the appropriate E/M service for the encounter in which it is provided (standard Medical Decision Making (MDM) or time based E/M). The complexity of a patient is not predetermined on all antepartum visits, but is assessed on an individual basis. Antepartum and fetal invasive procedural codes are still available as separate codes.
 

To help payers identify pregnancy-related encounters, practices should report:

• Use ICD-10-CM pregnancy codes including Z34- or applicable Chapter 15 pregnancy codes (O00-O9A)
• Practices should consider HCPCS modifier TH where applicable and when required or recognized by payer policy. 
• Modifier 25 is not a maternity identifier; it should be appended only when a significant, separately identifiable E/M service is performed on the same date as another reportable procedure or service and the documentation supports separate reporting. 

How is antepartum care reported under the CPT® 2027 framework?

Beginning January 1, 2027, antepartum care is reported for each individual encounter using the appropriate Evaluation and Management (E/M) code based on the location where the service is provided, such as an office, hospital, or telehealth setting. Standard E/M coding guidelines apply, and code selection is determined by either Medical Decision Making (MDM) or total time spent on the date of the encounter.

For services provided by a qualified healthcare professional (QHP) who is not eligible to report E/M services, the appropriate procedural code should be reported instead, such as those for genetic counseling or medical nutrition therapy. Existing procedural codes for antepartum and fetal invasive services remain available, although some services have been reassigned within the CPT® code set.

How can payers identify pregnancy-related services on claims?

To identify maternity-related encounters, providers should report the appropriate ICD-10-CM pregnancy diagnosis codes, including Z34- or applicable Chapter O codes. When appropriate, HCPCS modifier TH (Obstetrical treatment/services, prenatal or postpartum) may also be appended to indicate that the service is related to maternity care.

Will all antepartum visits be reported at the same level of complexity?

No. Under the CPT® 2027 revisions, each antepartum visit is reported independently using the appropriate E/M code. Code selection is based on the Medical Decision Making (MDM) or the total time documented for that specific encounter. The updated guidelines do not assign a fixed level of complexity to a patient throughout pregnancy, meaning every prenatal visit must be evaluated and coded according to the services provided during that individual encounter.

Labor Management: New Daily CPT® Codes

The CPT® 2027 maternity care system separates labor management from the hospital Evaluation and Management (E/M) services. After labor management starts, any E/M services by the same clinician on the same day will not be reported for labor. Rather, the management of labor will be charged on a per-day basis until delivery. If the delivery is planned or scheduled, it is not reported using labor management codes. The new code set also distinguishes between the first day of labor and the other days, as well as between simple and complex labor management. 

The new labor management CPT® codes include:

• 59080 – Initial day labor management; straightforward, per day
• 59081 – Initial day labor management; complex, per day
• 59082 – Subsequent day labor management; straightforward, per day
• 59083 – Subsequent day labor management; complex, per day

What distinguishes straightforward from complex labor management?

Under the CPT® 2027 guidelines, straightforward labor management applies only when all of the following criteria are met: a singleton fetus in a vertex presentation, routine maternal and fetal monitoring, fetal monitoring that does not require physician or qualified healthcare professional (QHP) intervention, normal labor progression or routine induction/augmentation, stable maternal medical conditions that require no additional management during labor, and no history of a previous cesarean delivery.

If any of these conditions are not met, such as multiple gestations, non-vertex, deteriorating maternal or fetal conditions, or a prior cesarean delivery, the labor management is reported as complex.

How are the initial-day and subsequent-day labor management codes apply?

The initial-day labor management code is reported for the first calendar day during the patient's facility admission when labor management begins. If labor continues beyond that date, subsequent-day labor management codes are reported for each additional calendar day that labor management is provided.

If a clinician shifts labor management responsibility to another, by means of medical necessity, to another clinician for a different specialty or group of clinicians, the clinician in receipt of the labor management may report the appropriate initial day labor management code for the services provided. 

Can labor management be reported together with other Evaluation and Management (E/M) services?

Once labor management begins, hospital Evaluation and Management (E/M) services provided by the same physician or qualified healthcare professional on that calendar day are not separately reportable. However, if an office or outpatient E/M service is furnished earlier that day and the patient was admitted later for labor management, both services may be reported when they meet the applicable CPT® reporting requirements.

Delivery: Reported as a Standalone Service

The maternity care framework, CPT® 2027, includes delivery separate from labor management and postpartum care. The new delivery codes aim to identify the services provided during delivery, rather than depending on a worldwide maternity package. Vaginal delivery codes also cover the delivery of the placenta, repair of first or second degree laceration and routine postpartum care on the same day. Cesarean Delivery codes cover the incision, delivery of the baby, removal of the placenta and stitching up the incision. 

The new delivery-related CPT® codes include:

• 59431 – Vaginal delivery, with or without episiotomy
• 59432 – Vaginal delivery, with or without episiotomy; after previous cesarean delivery
• 59414 – Delivery of placenta only, separate procedure (Do not report with CPT® 59431 or 59432.)
• 59300 – Repair of first- or second-degree episiotomy or laceration by a clinician other than the attending physician or qualified healthcare professional performing the vaginal delivery
• 59502 – Cesarean delivery; primary
• 59503 – Cesarean delivery; repeat
• 59504 – Subtotal or total hysterectomy performed during the same encounter as a cesarean delivery
• 59433 – Repair of episiotomy or laceration; third-degree laceration
• 59434 – Repair of episiotomy or laceration; fourth-degree laceration

How is vaginal delivery reported under CPT® 2027?

Beginning January 1, 2027, vaginal delivery is reported using one of two new CPT® codes, depending on the patient's clinical history:

• 59431 – Vaginal delivery, with or without episiotomy
• 59432 – Vaginal delivery, with or without episiotomy; after previous cesarean delivery

These codes include delivery of the placenta, repair of first- or second-degree lacerations performed by the delivering physician or qualified healthcare professional (QHP) or their group, as well as routine postpartum care provided on the same calendar day as the delivery.

How is cesarean delivery reported in 2027?

The CPT® 2027 update adds two codes to make specific use for cesarean delivery: 

• 59502 – Cesarean delivery; primary
• 59503 – Cesarean delivery; repeat

Each code includes the surgical incision, delivery of the infant, removal of the placenta, and closure of the incision. In most cases, a single cesarean delivery code is reported for each delivery event, regardless of the number of fetuses delivered by cesarean section. When applicable, labor management codes may also be reported separately, such as in cases involving failed labor before a primary cesarean or a trial of labor after cesarean (TOLAC) before a repeat cesarean delivery.

How are episiotomy and perineal laceration repairs reported?

Repairs of first- or second-degree episiotomies or perineal lacerations performed by the physician or qualified healthcare professional who reports the vaginal delivery are not separately billable, as these services are included in the vaginal delivery code.

If the repair is performed by a different, unrelated clinician, the following code may be reported:

• 59300 – Repair of first- or second-degree episiotomy or laceration, by other than the attending physician or other qualified healthcare professional performing vaginal delivery care (separate procedure)

Repairs involving third- or fourth-degree lacerations are reported separately regardless of who reports the delivery:

• 59433 – Repair of episiotomy or laceration; third-degree laceration
• 59434 – Repair of episiotomy or laceration; fourth-degree laceration

How are multiple gestations reported under the new guidelines?

For labor management, providers report one complex labor management code per calendar day, regardless of the number of fetuses, because labor involving multiple gestations is considered complex by default.

One cesarean delivery code is used for delivery services, irrespective of the number of fetuses delivered by cesarean section. In contrast, one vaginal delivery code is reported for each fetus delivered vaginally. If there are mixed mode deliveries (one infant vaginal and the remaining infants cesarean), then one code for vaginal delivery and one code for cesarean delivery should be reported. 

How are cesarean hysterectomies reported?

When a subtotal or total hysterectomy is performed during the same surgical encounter as a cesarean delivery, it is reported separately using the new CPT® code:

• 59504 – Subtotal or total hysterectomy performed at the same encounter as a cesarean delivery

This code may be reported by the same physician who performed the cesarean delivery or by a different physician, when appropriate.

Postpartum Care: Reported Using E/M Codes
 

Beginning January 1, 2027, current postpartum codes will be deleted, and postpartum care provided on the same calendar date of delivery is included with the delivery code.Inpatient maternal postpartum care on the days after delivery will be billed individually using E/M codes, just like antepartum care. Coverage durations for outpatient postpartum care vary by policy. There’s also a new code for postpartum hemorrhage management with uterine tamponade. The documentation and coding for outpatient postpartum visits remain the same as for all other E/M visits. 

A new CPT® code has also been introduced for postpartum hemorrhage management:

• 59623 – Uterine tamponade (e.g., balloon, catheter, vacuum, or packing material) for the management of postpartum hemorrhage.

How is postpartum care reported under CPT® 2027?

Under the CPT® 2027 maternity care framework, routine postpartum care provided on the same calendar day as delivery is included in the applicable delivery code and is not reported separately. After the day of delivery, inpatient postpartum care is reported on a per-day basis using the appropriate subsequent hospital care Evaluation and Management (E/M) codes until the patient is discharged. The discharge encounter is then reported using the appropriate hospital discharge day management code. Outpatient postpartum visits continue to be reported using the applicable E/M codes in accordance with standard E/M coding guidelines.

Are there any new postpartum procedure codes in CPT® 2027?

Yes. CPT® 2027 introduces a new procedure code for the management of postpartum hemorrhage:

• 59623 – Uterine tamponade (e.g., balloon, catheter, vacuum, or packing material) for the management of postpartum hemorrhage.

This code is in addition to pharmacologic treatment of postpartum bleeding. These revisions to the codes do not affect any existing CPT® codes that cover procedures like postpartum curettage (for retained products of conception) or hysterorrhaphy (uterine repair after uterine rupture). 

How do payer coverage timelines affect postpartum coding?

The updated CPT® 2027 guidelines define how postpartum services are reported, while payer policies determine how long those services are covered. Inpatient and outpatient postpartum care continues to be reported using the appropriate Evaluation and Management (E/M) codes. However, coverage periods, such as Medicaid postpartum benefits available for a specified number of days after delivery, are established by individual payer or state policies and do not change the CPT® coding requirements.

 

Why 2026 Is the Year to Prepare for CPT® 2027 

Deleted CPT codes will be invalid for any date of service on or after January 1, 2027, and claims systems and clearinghouses are expected to reject them outright. Practices that wait until late 2026 risk learning the new system while their revenue cycle already depends on it.

Revenue Risk

Each prenatal visit will now be subject to E/M documentation requirements on its own; if it fails to meet the requirements, the claim is at risk. For patients who start treatment before 2027 and give birth after, the transition to delivery is another challenge, as it needs to be handled carefully so that no billing mistakes are made. 

Documentation Burden

Each separately reported  prenatal and postpartum encounter must be supported by documentation appropriate to the service providedWhen applicable, E/M code selection is generally based on either medical decision-making or total time, according to the requirements of the reported E/M code. ICD-10-CM diagnosis coding and any applicable modifiers should be determined separately based on the documented circumstances and payer requirements.The practices that have been working on a bundle-and-pay basis for years may have to undergo some meaningful workflow change and the revenue leakage can be real if there is no updating of templates and workflows beforehand. 

Claims Editing and Payer Readiness

Health plans should start to look at contracts and fee schedules that contain the deleted global codes and update claims systems and edits, ensure vendor coordination and integration with state-specific contracts like Medicaid tracking rules. Claims editing logic must cover codes that may be reported together, codes that shouldn't be reported together, and unusual but valid situations, like a patient who is trying to have a baby who has a labor management code on the claim and a repeat cesarean delivery code. 

Commercial and Medicaid payers may each adopt their own transitional billing rules, so verifying payer-specific coverage guidance ahead of the deadline is an essential part of preparation.

Prepare for the first 2027 claim. Not after the first denial. 

The CPT 2027 maternity changes are more than an annual code update. They require OB/GYN practices to revise documentation templates, update payer-specific rules, update fee schedules, test claim edits, and train providers and office staff on encounter-based billing and reporting.
