Scope: Highmark BCBS MMC and CHPlus medical maternity services within this record; the notice also names HARP and EP but does not establish payer-family applicability.
Transition: The source uses and/or between the prenatal-initiation and estimated-due-date criteria. The article does not detail 2026 claim handling or cross-year episode billing; it refers providers to NYS Medicaid Update – April 2026 Volume 42 – Number 5.
Global billing: The notice moves away from legacy global maternity codes toward separate antepartum, labor-management, delivery and postpartum reporting. Antepartum and postpartum care use encounter-based E/M reporting; routine postpartum care on the delivery date is included in the delivery care code.
This is a program-specific coding notice, not merely an awareness article or evidence of an ongoing Highmark implementation review. Confirm the member's covered program and consult the referenced NYS Medicaid billing guidance for implementation details.
