New obstetric CPT codes poised to transform OB-GYN reimbursement

A set of new and revised CPT codes for obstetric care, effective January 1, 2027, will reshape OB-GYN reimbursement. The updates aim to better reflect resource use for complex pregnancies, postpartum care, and managing comorbidities like hypertension or diabetes during gestation. Practices must audit their current coding patterns against the new code set, update their charge masters, and brief clinicians on documentation requirements well before the 2027 implementation. Contact your MAC or payer representative for educational resources and fee schedule impacts as they become available later this year.
