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.

How to read this

AMA CPT 2027 retires global maternity packages (59400, 59510, 59610, 59618) in favor of itemized prenatal, delivery, and postpartum billing. Each payer sets its own timing.

The five statuses above, with these meanings: Confirmed 2027 guidance means the payer published final instructions. Proposed—not final means draft or announced, may change, don't bill on it yet. Pending payer guidance means the payer has not published instructions. Awareness notice only means the payer acknowledged the change without operational detail. Current policy only means the record reflects current policy or reference material. It does not by itself confirm that global billing continues.

Transition starts is when the payer begins the changeover. Billing starts is the first date of service that must be billed the new way.

Current as of October 2026. Verify against the linked payer source before submitting claims.

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 one PDF guide for that payer mix. It opens with background on the 2027 change, links to every cited payer policy, and each policy gets its own page with the verbatim payer guidance and source links. The source documents remain on each payer's website.

Which bundled maternity CPT codes are retired on January 1, 2027?

The following bundled CPT codes will be retired and should not be reported for dates of service on or after January 1, 2027: 59050, 59400, 59409, 59410, 59425, 59426, 59430, 59510, 59514, 59515, 59525, 59610, 59612, 59614, 59618, 59620, and 59622.

They cover labor management, vaginal and cesarean delivery, laceration repair, hysterectomy after cesarean delivery, and uterine tamponade.

How many codes were changed in total?

35 total codes were changed, including 17 deleted codes, 12 new codes and 6 revised codes.

Why are these updates being made?
