New Obstetric CPT Codes Poised to Transform OB-GYN Reimbursement

Long-anticipated changes to the Current Procedural Terminology (CPT) coding structure for obstetric care were among the most discussed topics at the 2026 ACOG Annual Clinical & Scientific Meeting, drawing significant attention from clinicians who have spent years providing complex antepartum and postpartum care that the existing framework failed to adequately capture. In the third segment of this program, Maryam Siddiqui, MD, vice chair for clinical affairs and section chief for general obstetrics and gynecology at the University of Chicago Medicine, and Katrina Lee, MD, an assistant professor of obstetrics and gynecology at the University of Chicago Medicine, examine what the new codes represent—both practically and symbolically—for a specialty that has long felt its cognitive and clinical contributions were undervalued by prevailing reimbursement models.

Siddiqui observed that the previous global obstetric billing structure treated patients with uneventful pregnancies the same as those with extensive antepartum complications or complex postpartum needs, obscuring the real variation in clinical effort and expertise required. The new CPT codes are designed to allow more granular documentation of care delivered across the continuum of pregnancy, enabling practices to more accurately represent the work performed for each individual patient. Lee echoed this perspective, noting that the changes reflect a meaningful acknowledgment of what obstetrician-gynecologists have consistently reported: that the delivery itself is only one component of a far more demanding episode of care.

Both physicians acknowledged that full implementation will require coordination across electronic medical records, payer contracts, and coverage models, with ACOG signaling a rollout timeline beginning in January, with preparatory guidance available as early as September. Siddiqui and Lee encouraged clinicians to begin familiarizing themselves with the new framework now, framing the coding changes not as administrative complexity but as an opportunity to advocate more effectively for fair compensation—and, by extension, to support the long-term sustainability of obstetric practice in underserved communities and non-urban settings.
