For more than 30 years, maternity has been one of the few places in healthcare where a nine-month journey arrived as a single line item. That ends next year.
The AMA’s CPT Editorial Panel has approved a full restructuring of codes for maternity care services, retiring the global obstetric codes and replacing them with service-level reporting across four distinct phases of care. Effective January 1, 2027, maternity care coding will transition away from the longstanding global billing model toward a framework that separately reports antepartum care, labor management, delivery, and postpartum services.
For benefit leaders, this is not a coding footnote. It is a structural change to how maternity spend appears in your claims data, and it lands in the middle of a year when a fifth of employers already name maternity-related costs among their top cost drivers. Across Truven’s book of business, 76% of patients with a delivery had global billing and have direct exposure to this coding transition.
Why should employers and payers care about maternity coding changes?
This transition may create new opportunities for commercial payers to understand how maternity care is delivered and measured. Beyond its reimbursement implications, greater coding specificity may improve visibility into aspects of maternal care that have historically been embedded within global billing arrangements. This additional detail could support stronger measurement of maternal mental health services, postpartum follow-up, management of pregnancy-related comorbidities, and other quality-focused initiatives. The extent of these benefits will depend on how payers, providers, and other stakeholders implement and use the new information.
Visibility improves. Itemized billing means you will finally see where maternity dollars originate: specialist utilization, prenatal visit patterns, postpartum follow-up rates, emergency room visits, escalating high-risk cases, rather than a single bundled claim arriving months after delivery. That is the foundation for risk stratification, quality measurement, and provider accountability that the bundle has obscured for a decade.
Predictability worsens. Unbundling introduces cost variability and forecasting volatility, particularly for populations with a high share of IVF pregnancies or pregnancies complicated by diabetes and hypertension. Even where the change is described as budget neutral, a fee-for-service structure inherently rewards more services, sometimes at higher levels of complexity.
Claims get noisier. Expect a transition period of coding updates, processing errors, claim denials, and member confusion, especially for pregnancies that straddle 2026 and 2027. Billing shifting to one-day increments for labor and delivery will affect claims processing and payment logic. And there is a real member cost-share question: once routine antepartum and postpartum visits are billed separately, some may fall under preventive benefits with no member cost share rather than inside a cost-shared global package.
Provider mix may shift. Midwives and birth centers serving mostly low-risk pregnancies could face meaningful revenue disruption if reimbursement patterns move, while more granular billing creates openings for maternity centers of excellence and targeted postpartum strategies.
What payers and plan sponsors should do before January 2027
There are several key steps that payers and plan sponsors can take to prepare for this change:
-
Establish baseline maternity reimbursement and utilization metrics
-
Evaluate how maternity reporting and episode definitions may need to evolve
-
Monitor professional maternity reimbursement separately from facility costs
-
Assess potential changes in member cost-sharing patterns
-
Explore opportunities to strengthen maternal health analytics, quality measurement, and population health programs
-
Revisit alternative purchasing models including bundled payments, centers of excellence, and provider contracting
Although the changes directly affect how maternity services are coded and reported, their implications may extend beyond claims administration. More granular reporting could inform quality measurement, care management, and future efforts to improve maternal outcomes. Realizing those opportunities, however, will depend on how organizations translate the resulting data into coverage policies, provider engagement, and care-delivery initiatives.
Whether preparing for implementation or evaluating post-transition impacts, Truven can help organizations understand how the coding changes affect reimbursement, reporting, member cost sharing, and maternal health analytics while supporting ongoing monitoring and strategic decision making.
