The invisible invoice: Estimating maternity unbundling costs
Starting January 1, 2027, maternity care stops being billed as a single global code and starts being billed line by line — labor and delivery, prenatal and postpartum visits — each itemized and priced on its own.
Why this actually matters
In an early look at claims data, roughly 80% of members will see some kind of line-item impact from unbundling, affecting approximately 20% of their total maternity spend.
An early estimate of unbundling’s impact may increase the maternity code bundle by 5–10%, based on unbundling trends across healthcare. While this may not seem like a seismic shift, maternity is typically in the top three areas of spend for an employer, meaning small impact can have a meaningful effect.
What unbundling will do
Puts a price tag on line items that were already happening, which may cause small shifts in billing, coding, and care delivery.
What actually moves the dollars
High-risk pregnancies and NICU stays — a small share of the population driving a disproportionate share of spend, and still in an employer’s control before the claim exists.

Watch the bundle come apart
Starting January 1, 2027, maternity billing splits into itemized charges. We modeled what that split could cost [Company name] — bundled, itemized, and with Maven’s clinical model in place.
Standard Delivery
An uncomplicated, full-term vaginal delivery — no NICU stay, no major complications. This is the pregnancy most cost models are built around, and the one most likely to understate what’s coming under itemized billing.
Under the current global billing code, prenatal care, delivery, and postpartum follow-up are paid as a single package rate — one line on the claim.
Global maternity care — prenatal care, ~13 routine visits, delivery and postpartum, all under one code
Starting January 1, 2027, that same care is billed as three separate phases. The total doesn’t automatically go up — it depends on how closely billing tracks guideline-recommended care.
Difference from bundle: +$43 (+1.94%)
Maven’s clinical model is built around ACOG-aligned care pathways — the same standard itemized billing now prices against. Maven’s role isn’t to beat the itemized total on paper; it’s to keep this pregnancy in the low-risk, low-cost category in the first place.
- 2:1 clinical ROI on near-term medical cost savings
- 4:1 total business ROI, incl. productivity + RTW gains
- Up to $9,600 saved per birth
- Up to 27% lower NICU admission rates
- Up to 15% lower C-section rates
Validated across 25,000+ pregnancies in independent, claims-based analyses.
High-Risk Pregnancy
A pregnancy involving a NICU admission, extended maternal complications, or both. A small share of pregnancies that can drive a disproportionate share of claims cost.
Maternal health factors
Pre-existing or pregnancy-related conditions: hypertension or preeclampsia, gestational diabetes, obesity, autoimmune conditions, advanced maternal age (35+), or a prior C-section/complicated delivery.
Pregnancy-specific factors
Things that emerge during this pregnancy: multiples (twins/triplets), placental issues, preterm labor risk, or a fetal growth/anatomy concern flagged on imaging.
Situational/access factors
Late or inconsistent prenatal care, conception via fertility treatment (which independently raises multiples and preterm risk), or limited access to maternal-fetal medicine specialists.
How unbundling will impact this: none of these factors are things a billing code change touches. But they’re the reason a pregnancy escalates into a NICU stay or an extended delivery admission — and where costs start to snowball.
Maven’s care model doesn’t wait for a complication to happen — it works to prevent one. High-risk members are proactively enrolled in dedicated coaching.
- Birth planning appointment: 40% lower NICU risk, 67% lower preterm birth
- Childbirth education class: 39% lower NICU risk, 44% lower preterm birth
- Doula engagement: 15% lower C-section risk
Fewer complications means fewer of the high-cost claims that itemized billing will now make visible line by line — which is where the savings actually come from.
