Highmark Blue Cross Blue Shield (NY) - Medicaid and CHP
NYTransition starts June 1, 2026
For this record, the notice applies to MMC and CHPlus maternity services, not to dental or vision benefits. It announces CPT maternity restructuring effective January 1, 2027 and directs all NYS Medicaid-enrolled providers of antepartum, postpartum, labor and delivery services to use the restructured system for individuals initiating prenatal care on or after June 1, 2026 and/or having an estimated due date on or after January 1, 2027.

Scope: MMC and CHPlus medical maternity services within this record. No dental, vision or payer-family implementation scope is established.
Transition: The prenatal-initiation and estimated-due-date criteria are joined by 'and/or.' The article does not detail 2026 claim handling or cross-year episode billing and directs providers to NYS Medicaid Update – April 2026 Volume 42 – Number 5.
Global billing: The notice replaces legacy global maternity reporting with phase-specific reporting, including encounter-based antepartum and postpartum E/M services, separate labor management and delivery-only codes. Routine postpartum care on the delivery date remains included in the delivery care code.
The source is an explicit program-limited coding notice, not evidence that Highmark is still reviewing implementation. Confirm the member's MMC or CHPlus product and consult the referenced NYS Medicaid guidance for additional billing details.
