Effective January 1, 2027, the American Medical Association (AMA) is implementing a major restructuring of CPT® coding for maternity care services. This overhaul represents one of the most significant changes to obstetric coding in more than three decades, with direct implications for OB/GYN revenue cycle management, Maternal-Fetal Medicine (MFM) billing, and healthcare financial operations.
While final code sets are still pending publication, current guidance signals a meaningful shift away from traditional global maternity packages toward a more granular, encounter-based coding framework. For OB/GYN and MFM practices, this transition will require careful alignment of clinical documentation, coding workflows, and revenue cycle strategy.
Note: Details described reflect preliminary guidance from the AMA that are publicly available as of March 2026 and may change upon final publication of CPT 2027.
Why the Change?
The current maternity CPT code structure is more than 30 years old with minimal changes. In that time, obstetric care has evolved significantly. Specialty groups, including the American College of Obstetricians and Gynecologists (ACOG), successfully advocated that modern obstetric services—especially those involving high-risk MFM patients—are far more complex than the current global coding system can accurately capture.
Care variations that prompted the change include:
- Increasing patient acuity and medical complexity in OB/GYN care
- Greater involvement of MFM specialists in high-risk pregnancies
- Expanded focus on maternal morbidity drivers, including cardiovascular disease, mental health, and obstetric hemorrhage
- Variability in care settings, including tertiary referral centers and telehealth-enabled prenatal care
The proposed restructuring is intended to improve coding accuracy, better align reimbursement with clinical intensity, and support more transparent OB/GYN billing and revenue cycle management processes.
The Four New Phases of the 2027 CPT Maternity Care Overhaul
The AMA’s proposed model organizes maternity services into four distinct phases: antepartum care, labor management, delivery care, and postpartum care. Although specific CPT codes and descriptors remain subject to finalization, the structural shift is expected to impact nearly every aspect of OB/GYN billing workflows. The current proposal from the AMA includes an introduction of 12 new codes, deletion of 17, and revision of 6. The new coding framework breaks maternity care into four distinct phases.
Phase 1: Antepartum Care
The days of bundling prenatal visits into a single global maternity code are ending.
- Proposed Deleted Codes: Global antepartum-only codes (59425, 59426) and the antepartum portions of all full global codes (59400, 59510, 59610, 59618) will be deleted or substantially restructured.
- Antepartum care will now be reported per encounter using appropriate Evaluation and Management (E/M) service codes based on the location of the patient (992XX codes).
- This allows practices to capture variations in E/M codes based on the specific services provided at each encounter, such as telemedicine or nurse-only visits.
- When determining the E/M level based on Medical Decision Making (MDM), pregnancy will be evaluated under the “Problem(s) Addressed” category.
Phase 2: Labor Management
Historically, labor management did not have separate codes and was bundled into global care or delivery codes. Recognizing the increasing complexity of modern labor, the AMA has introduced a brand-new section for Labor Management.
- Added Codes: Four new codes will distinguish labor management based on the day and complexity: 59XX1 (Initial day, straightforward), 59XX2 (Initial day, complex), 59XX3 (Subsequent day, straightforward), and 59XX4 (Subsequent day, complex).
- Proposed Deleted Code: Code 59050 (Fetal monitoring during labor by consulting physician) is being deleted.
- “Initial Day” is reported on the first calendar date induction begins or the expectant mother requires labor management services.
- Straightforward labor management involves factors like a singleton vertex presentation, routine monitoring, and stable medical conditions.
- Once labor management begins, all other E/M services (like hospital care) stop.
Phase 3: Delivery Care
Delivery care will no longer be tied to global packages. The focus has shifted to accurately capturing the specific clinical scenario.
- Added Codes: There are four new delivery care codes: 59XX5 (Vaginal delivery), 59XX6 (Vaginal delivery after previous cesarean), 59XX7 (Primary cesarean), and 59XX8 (Repeat cesarean). A new code, 59XX9, has also been added for a subtotal/total hysterectomy after a cesarean.
- Deleted Codes: All previous delivery-only and delivery/postpartum codes are being deleted. This includes 59409, 59410, 59514, 59515, 59612, 59614, 59620, and 59622. The previous hysterectomy code (59525) is also deleted.
- Lacerations: The work of repairing 1st and 2nd-degree lacerations or episiotomies is bundled into the vaginal delivery codes. New codes were added to separately report the increased work of repairing more complex lacerations: 59X11 (3rd-degree repair) and 59X12 (4th-degree repair).
For OB/GYN revenue cycle management, these changes underscore the need for precise operative documentation and coding specificity to ensure appropriate reimbursement.
Phase 4: Postpartum Care
Like antepartum care, routine postpartum care is shifting to an E/M framework.
- Deleted Codes: All current postpartum care codes will be deleted, including the standalone 59430.
- For facility births, providers will use appropriate subsequent hospital care codes for each management day and discharge day management codes on the day of discharge.
- Outpatient E/M services (99212-99215) will be used for postpartum care after discharge.
- Routine postpartum care may not be reported on the same day as the delivery care.
- Added Code: A new procedure code, 59X10, has been introduced for uterine tamponade (e.g., balloon, catheter, vacuum, packing material), but it cannot be reported for pharmacologic management of hemorrhage.

Revenue Cycle Management Implications for OB/GYN and MFM Practices
The 2027 CPT® maternity care overhaul will have far-reaching implications for healthcare revenue cycle management, particularly within OB/GYN and Maternal-Fetal Medicine.
Key operational impacts include:
- EHR and template redesign to support encounter-based documentation
- Increased reliance on E/M coding accuracy and audit readiness
- Updates to charge capture workflows across inpatient and outpatient settings
- Staff education and training for coding, billing, and compliance teams
- Greater sensitivity to payer-specific reimbursement policies as global billing structures evolve
Organizations that proactively adapt their OB/GYN revenue cycle management strategies will be better positioned to maintain financial stability and compliance during this transition.
Preparing for CPT® 2027
The AMA has released early guidance to allow healthcare organizations sufficient time to prepare for implementation. However, given the scale of change, OB/GYN and MFM practices should begin planning now.
A successful transition will depend on coordination across clinical, coding, and revenue cycle teams—ensuring that documentation supports coding specificity, workflows align with new reporting requirements, and financial performance remains protected.
As additional details emerge with the final CPT® 2027 publication, ongoing monitoring and adaptation will be essential for all stakeholders involved in obstetric care delivery and revenue cycle management.

Why Kovo RCM is Your Ideal Partner for 2027
The AMA’s CPT Editorial Panel intentionally released these codes early because implementing them is a massive undertaking. Practice managers and providers will need to update EHR templates, redefine clinical documentation requirements to meet E/M and labor complexity criteria, and retrain staff.
