In 2027, significant maternity care Current Procedural Terminology (CPT)[1] coding changes will alter how obstetric (OB) services are reported and billed, how physician productivity is measured, and how provider compensation plans may need to be designed. While the Centers for Medicare and Medicaid Services (CMS) CY 2027 Medicare Physician Fee Schedule proposed rule (MPFS) includes several notable proposed payment and coding updates, the retirement of traditional global obstetric CPT codes will directly impact work relative value unit (wRVU) attribution, physician compensation, and market benchmarks. Medicare payment policy for 2027 remains subject to final rulemaking and includes proposed policies that may affect how these changes are implemented.

Why Three Decades of OB Bundled Billing Is Coming to an End
Since the 1990s, maternity care has largely been billed through a single bundled global code covering antepartum visits, delivery, and postpartum care in one payment when provided via a single entity, regardless of how many visits occurred or which clinicians provided them.
Now, the American Medical Association (AMA), with strong support from the American College of Obstetricians and Gynecologists (ACOG), has moved to retire the bundled model to more closely align with today’s maternity care, which is frequently team based within a single entity. The AMA and ACOG state that the current bundled codes do not reflect the providers who actually performed the work and that individual productivity attribution is difficult in the current model. Additionally, the organizations state that the traditional 12–14 visit antepartum model no longer reflects modern prenatal care, telehealth, home monitoring, and risk-adjusted visit patterns.
What is OB Global Code Unbundling?
Beginning January 1, 2027, traditional bundled global obstetric CPT codes will be replaced with separate reporting for antepartum care, labor management, delivery, and postpartum care. Instead of a single global code representing the maternity episode, physicians and other clinicians will report the specific services they personally perform. This more granular reporting framework is expected to allow wRVU productivity and professional reimbursement to be more closely aligned with actual work performed without requiring organizations to define how credit is assigned in team-based care compensation arrangements. The unbundling introduces a new framework for measuring and crediting physician and non-physician provider work, leading organizations to move toward obstetrics provider compensation design that credits personally performed work and establishes transparency for team-based care attribution.
What Will Change in OB Coding in 2027?
Beginning in January,[2] each phase of maternity care will be billed separately:
- Antepartum care will be reported using appropriate evaluation/management (E/M) codes based on services provided
- Labor management will use new CPT codes 59080-59083, with distinctions for initial versus subsequent day management and straightforward versus complex care
- Delivery will be separately reported using delivery-specific CPT codes
- Postpartum care will use appropriate E/M codes
These changes shift obstetric maternity care from a bundled CPT reporting model to more service-level attribution. Payer payment policy, claim edits, modifier requirements, and transition timing may vary depending on whether the payer payment policies and contracts follow AMA or CMS.
Compensation and Productivity Implications of the OB Changes
Under the unbundled CPT reporting model, organizations will need to understand how this new methodology impacts provider compensation now that wRVUs are credited for antepartum visits, labor management, delivery, and postpartum follow-up, particularly when more than one clinician participates in a maternity episode. Compensation treatment will depend on payer adoption, billing workflows, employer compensation-plan language, internal attribution rules, and transition policies.
A Break in Historical Productivity Trends
Organizations should be prepared for a significant break in historical obstetrics wRVU and compensation-per-wRVU trends. Because the underlying coding structure is changing, historical wRVU performance will no longer be directly comparable to post-2027 productivity data.
Healthcare leaders are encouraged to run parallel wRVU projections under the old bundled model and the new unbundled model and consider a one-year stabilization plan during implementation. This will help avoid a potential misinterpretation of productivity and compensation data without proper context.
wRVU Benchmark Challenges Ahead
Major fee schedule revisions can take several survey cycles to stabilize, and benchmark data may require 2–3 years before meaningful comparisons can be made. Organizations should evaluate compensation, wRVUs, professional collections, and MPFS year together when reviewing market data and confirm which MPFS year was used in the surveys. During the transition period, organizations should avoid making provider compensation decisions based solely on raw wRVU comparisons and recognize that benchmark volatility may not reflect changes in physician effort or performance.
What Strategies Should Healthcare Organizations Use Now to Prepare for OB Code Unbundling?
To prepare for the obstetrics billing model restructure, organizations should consider several strategies for provider compensation design:
- Credit personally performed wRVUs instead of relying on historical global package attribution methodologies
- Address team-based attribution to determine how productivity and compensation will be assigned when multiple clinicians participate in a maternity care episode
- Pay laborists and call coverage clinicians separately from productivity-based incentives where appropriate
- Run parallel (shadow) productivity analyses using the current bundled model and the 2027 unbundled model to identify compensation disruptions before go-live
- Consider a stabilization period to provide time for provider compensation plan redesign and physician education
Other MPFS Changes to Watch
Several additional proposed Medicare changes could affect physician compensation:
- G2211: Proposed to shift from a flat add-on code to a percentage-based modifier, increasing payment by 16% for most clinicians and 32% for Medicare Shared Savings Program/Long-term Enhanced ACO Design participants
- Same-Day E/M and Procedure Changes: Proposal from CMS to pay the highest-value same-day service at 100% and additional services at 50%
- Efficiency Adjustment: Continuing from 2026, a 2.5% wRVU and intraservice time reduction affecting many procedural services while exempting E/M visits and maternity codes
- Conversion Factor Declines: Proposed conversion factors of $33.1693 for qualifying APM participants and $32.8409 for non-qualifying APM participants, reflecting decreases from 2026 levels
- Remote Patient Monitoring/Remote Therapeutic Monitoring Changes: Revised staffing requirements and potential code consolidation
Key Takeaways
The obstetric services global code overhaul is more than a coding update. It is a fundamental reset of productivity attribution, physician compensation, and benchmark interpretation. PYA’s Healthcare Provider Compensation Valuation Planning and Design team can help healthcare organizations prepare now by modeling the impact of unbundled coding, reviewing compensation methodologies, educating physicians and compensation committees, implementing shadow reporting, and considering stabilization periods during the transition. Organizations that anticipate the shift rather than react after survey data resets will be best positioned to navigate the new compensation reality.
