2027 Substrate Maternity Resource Center

Global billing for maternity is ending.

Today, maternity care is largely billed using a "global" code. Beginning January 1, 2027, CPT revisions will allow care to be reported more granularly at the service level. January 1 is the CPT effective date, but each payer might choose to transition billing on their own timeline.

The 2027 Substrate Maternity Resource Center tracks which of your payers are moving off global maternity billing, so you can adapt proactively. For more background, see the AMA CPT 2027 maternity care services update.

For this record, apply the notice only to matching MMC, HARP, CHPlus or EP medical maternity services. The article announces CPT 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.

Billing notes and scope

Scope: Highmark BCBS MMC, HARP, CHPlus and EP medical maternity services only. No commercial, Medicare, dental, vision or Highmark Group-wide adoption is established.

Transition: The source joins prenatal-initiation and estimated-due-date criteria with 'and/or.' It refers providers to NYS Medicaid Update – April 2026 Volume 42 – Number 5 and does not itself detail pre-2027 claims or cross-year episode handling.

Global billing: The notice moves away from legacy global maternity coding toward separate reporting by phase of care. Antepartum and postpartum reporting uses E/M encounters, labor management is separate, and delivery codes are delivery-only, with routine same-day postpartum care included.

This is a program-specific coding instruction, not evidence of an unresolved Highmark implementation review. Confirm the member's program; do not inherit this directive across other products or the payer group.

Frequently asked questions

What you need to know

Is global billing for maternity ending everywhere at once?

No. CPT revisions take effect January 1, 2027, but that is not each payer's billing date. Search tracked payers to see who published a transition date, whose guidance is still proposed, and whose policies are unchanged.

What is changing about maternity billing in 2027?

Today, maternity care is largely reported using a global code. Beginning January 1, 2027, CPT revisions will allow care to be reported more granularly at the service level. Whether and when a payer moves off global billing depends on that payer's own policy.

How do I see what’s changing by payer in my market?

Search the 2027 Substrate Maternity Resource Center by payer, then open the primary policy. Confirm the transition and billing dates, and recheck the source before submitting claims. This is policy intelligence, not coding or legal advice.

Can I download policies for multiple payers?

Yes. Select payer cards and download an offline source packet containing the policy summary plus links to the maternity policy and the payer policy homepage. The source documents remain on each payer's website.
