Understanding the 2027 CPT Maternity Coding Changes
Maternity coding is undergoing a significant transformation for CPT® 2027. Historically, coding for maternity care has relied heavily on global obstetric packages that combine services provided throughout pregnancy, delivery, and the postpartum period. Beginning January 1, 2027, that framework changes substantially.
The revised structure places greater emphasis on the individual phases of maternity care: antepartum care, labor management, delivery, and postpartum care. For coders, this means moving away from viewing pregnancy as one global episode and looking more closely at the care provided during each phase.
Antepartum Care Moves to E/M Reporting
One of the most notable changes involves antepartum care, or care provided before the onset of labor. Under the 2027 structure, current antepartum-only maternity codes are eliminated, and antepartum visits are reported using the appropriate evaluation and management (E/M) code based on the setting. This may include office or outpatient, telemedicine, home or residence, hospital inpatient or observation, and critical care services.
The calendar-year transition will also require attention. For care performed during 2026, the existing CPT structure remains applicable. Beginning with 2027 dates of service, antepartum encounters are reported individually using E/M codes.
Coders should also recognize that separately performed antepartum procedures, fetal invasive services, and applicable diagnostic imaging may be reportable in addition to the antepartum E/M service.
Labor Management Becomes a Separate Service
Another major change is the introduction of a distinct labor management framework.
Labor management includes the clinical decision making necessary to assess and support the fetus or fetuses and the pregnant patient in labor (parturient). Interim examinations, collection and interpretation of physiologic data, and routine induction or augmentation activities are included in labor management and are not separately reported.
Labor management is categorized as either initial or subsequent, and straightforward or complex. In general, the service requires a face-to-face encounter and is reported once per calendar date. Multiple encounters by the same physician or qualified healthcare professional, or the same group practice, during the same calendar date are combined into a single labor management service. A continuous encounter that crosses midnight is also considered a single service.
When labor continues across multiple calendar dates, subsequent labor management may be reported for later dates when the applicable requirements are met. Labor management may also be reported on the date of delivery when labor management services are performed.
Straightforward Versus Complex Labor
Determining the complexity of labor will become an important coding responsibility.
Straightforward labor requires the criteria defined by CPT to be met, including factors such as singleton vertex presentation, routine maternal and fetal monitoring, normal labor progression or routine induction or augmentation, stable medical conditions that do not require additional management during labor, and no previous cesarean delivery. If the requirements for straightforward labor are not met, coders should refer to complex labor management.
Examples of circumstances associated with complex management include:
- Multiple gestation
- Fetal monitoring abnormalities requiring intervention
- Prolonged labor
- Maternal or fetal complications
- Medical conditions requiring additional management
- Previous cesarean delivery
Importantly, the length of labor alone does not establish complexity unless prolonged labor is diagnosed. If care progresses from straightforward to complex during the same calendar date, the highest level of labor management performed for that date is reported.
Delivery Is Separate from Labor Management
The revised structure also creates a clearer distinction between labor and delivery. Vaginal and cesarean delivery services do not include the work of labor management.
For vaginal delivery, the service includes delivery of the fetus and placenta, as well as repair of a first- or second-degree episiotomy or spontaneous laceration. New vaginal delivery coding distinguishes a vaginal delivery from a successful vaginal birth after previous cesarean delivery (VBAC). If a trial of labor after cesarean is unsuccessful and a repeat cesarean is performed, the repeat cesarean delivery is reported. Reporting of a breech delivery will require the use of modifier 22 on the vaginal delivery code.
Coding examples include:
- 59431 – Vaginal delivery, with or without episiotomy
- 59432 – After previous cesarean delivery
Coders must also understand what is included in the delivery service. First- and second-degree laceration repairs are included when performed by the clinician reporting the vaginal delivery. Third- and fourth-degree repairs may be separately reportable. Placental delivery may also be separately reported when performed by an eligible physician or other qualified healthcare professional who did not perform the vaginal delivery.
For cesarean delivery, CPT 2027 distinguishes primary from repeat cesarean delivery. Labor management may accompany an unscheduled cesarean occurring after labor, while a planned cesarean in a patient who is not in labor does not support reporting labor management.
Coding examples include:
- 59502 – Cesarean delivery; primary
- 59503 – Repeat
The move away from global maternity coding continues after delivery. Ongoing maternal postpartum assessments are reported using the appropriate E/M service. Timing is critical. Immediate postpartum care provided on the same calendar date as the delivery is included in the delivery service. Postpartum care provided on a later calendar date may be reported using the appropriate E/M code for the setting.
Preparing for Change
To help coders prepare for the changes, AHIMA is offering the on demand webinar, “Delivering Change: What Coders Need to Know About CPT® 2027 Maternity Services.” The 2027 maternity revisions represent more than a change in code numbers. They change how coders evaluate an entire maternity episode.
Instead of beginning with a global package, coders will need to identify the phase of care, setting, complexity of labor, type of delivery, timing of postpartum care, and which clinician performed separately reportable services.
Understanding that framework will be central to accurate maternity coding in 2027 and will help coding professionals move from global reporting to a more detailed, service-specific approach.
