Global maternity billing hides revenue loss because your practice delivers up to ten months of care before a single claim is filed, so leakage never appears as a denial, an AR balance, or a variance alert.
For multi-provider OB-GYN groups, that blind spot sits inside the highest-value service line in women’s health.
MBC has already covered which services fall outside the global bundle and why global package denials are rising in 2026. This piece addresses an earlier global maternity billing problem: revenue that never reaches a claim at all.
Follow One Pregnancy Through the Global Maternity Billing Blind Spot
For that reason, the clearest way to see the problem is to track a single patient.
Week 8. The patient starts prenatal care with your group under a UnitedHealthcare commercial plan. Your team logs her visits but does not bill them, because the practice expects to submit CPT 59400 for global maternity billing after delivery.
Week 20. Her employer changes carriers. Nobody re-verifies eligibility, so the chart still shows UnitedHealthcare. Every visit since week 8 now belongs to a payer that will never receive a global claim.
Week 32. She relocates and transfers care to another group. Your practice will not deliver, so the global package is gone. The correct global maternity billing response is component billing: 59426 for seven or more antepartum visits, split by payer.
The problem. In global maternity billing, timing is everything. UnitedHealthcare’s commercial in-network filing limit is 90 days from date of service under its provider administrative guide. Visits from weeks 8 through roughly 19 are already past that window. Your practice has permanently lost that revenue, and because nobody ever submitted a claim, no denial code records the loss.
Medicare allows 12 months for global maternity billing under 42 CFR 424.44, and state Medicaid windows vary. However, commercial contracts are where the clock runs out fastest.
Why Global Maternity Billing Loss Never Shows Up in Your Reports
Most practice management systems report on claims. No claim means no denial, no AR aging entry and no payer variance flag.
However, paid global claims hide loss too. A global payment posted below contracted rate clears posting without review. In addition, the global payment often absorbs separately billable services, including ultrasounds (76805, 76815), non-stress tests (59025) and E/M visits for unrelated conditions with Modifier 25, when your team should bill them separately.
As a result, the practice sees delivery volume hold steady while maternity collections drift down, with no report explaining why.
What One Review Found
Illustrative scenario. A group with weak global maternity billing controls, managing 120 active pregnancies per month, with 10% experiencing an untracked chain break that forfeits $1,200 each, would lose $14,400 per month, or $172,800 per 12 months, with no denial on record. These figures are assumptions for illustration, not MBC client results.
| Global Maternity Billing Leakage Point | Why It Stays Invisible | Revenue Consequence | Required Control |
|---|---|---|---|
| Mid-pregnancy payer change | Global billed to wrong payer or not split | Denial or recoupment months later | Eligibility re-verification each trimester |
| Transfer of care | No claim generated for prior visits | Antepartum components never billed | Chain-break trigger to component billing |
| Pregnancy loss | Visits held for a global that never comes | Visits age past filing limits | Pregnancy-level ledger with filing alerts |
| Below-contract global payment | Paid claim, no denial | Silent underpayment on every delivery | Payer variance detection |
| Bundled separately billable services | Absorbed into global payment | Lost ultrasound, NST and E/M revenue | Pre-bill coding review |
Five Global Maternity Billing Controls That Make Revenue Visible
- A pregnancy-level ledger tracking every patient from care initiation through postpartum, with visit count, payer and expected global billing date.
- Eligibility re-verification each trimester, so payer changes surface before they break the global claim.
- Chain-break triggers that route transfers, losses and payer changes to component billing while visits are still inside filing windows.
- Payer variance detection on every paid global claim, compared against contracted rates.
- Unbilled global maternity billing work-in-progress as a CFO KPI, reported alongside AR rather than buried beneath it.
Global Maternity Billing Questions to Ask Your Team This Quarter
- How many active pregnancies sit in our global maternity billing pipeline right now, and what is their unbilled value?
- How many chain breaks did we record in the last 90 days, and how fast were they billed?
- Which payers in our mix enforce 90-day filing limits?
- When did we last compare paid global claims against contracted rates?
If the answers take more than a day to produce, your team is not tracking the revenue.

Frequently Asked Questions
AR reports track submitted claims. Practices submit global maternity billing after delivery, so months of antepartum visits exist as work performed with no claim attached. When a pregnancy falls out of the global chain and nobody bills the components, the loss never produces a claim, denial or balance.
In general, component billing applies when the same group does not provide all antepartum, delivery and postpartum care. Common triggers for leaving global maternity billing include insurance changes, transfers of care, relocation and pregnancy loss. The switch should happen when the event occurs, not at delivery, so earlier visits remain inside payer filing windows.
When global maternity billing no longer applies, antepartum care uses 59425 for four to six visits or 59426 for seven or more, with one to three visits billed as E/M services. Delivery-only codes include 59409, 59514, 59612 and 59620. Postpartum-only care uses 59430. In short, selection depends on which components your group provided.
Yes. A global claim paid below contracted rate clears posting without a denial, and the global payment often absorbs separately billable services. As a result, both losses stay hidden unless your team compares every paid claim against contract terms through payer variance detection.
