Reminder: Obstetrical Providers Encouraged to Use E&M Codes with Modifier TH
Effective November 1, 2026, Medi-Cal encourages obstetrical providers to submit claims for prenatal and postpartum care using E&M codes (99204, 99205, 99213, 99214, 99215) with modifier TH instead of global obstetric codes. This change anticipates the AMA's January 1, 2027 replacement of the global obstetric CPT code structure, allowing separate identification of antepartum, labor, delivery, and postpartum services. Claims must include appropriate gestational age ICD-10 codes (Z3A.00-49 for prenatal) or postpartum codes (O86-O92, Z39.0-2, F53.0-1).
