Summary
Effective January 1, 2027, the AMA is replacing the current global obstetric CPT code structure with a disaggregated model that separately identifies antepartum care, labor management, delivery care, and postpartum services. California's Medi-Cal program intends to align with these changes pending CMS approval. Billing teams must prepare documentation and workflow changes to accommodate the new maternity care coding structure.
