Global Maternity Billing: How OB-GYN Practices Are Losing Revenue and How to Prevent It
An OB-GYN practice can deliver excellent maternity care and still lose revenue on the billing side. The patient is seen throughout pregnancy, the delivery goes well, the postpartum visit happens. Then the claim is denied, paid at a lower amount than expected, or never sent because something was missed along the way.
Global obstetric billing packages months of care into one claim, which means small gaps in eligibility, documentation, or coding can have large effects. Our billing specialists wrote this guide to show where the leaks usually happen and how a practice can reduce them. It is practical, not promotional.
What Is Global Maternity Billing?
Global maternity billing reports routine obstetric care as a package rather than visit by visit. The package generally covers antepartum care, the delivery, and postpartum care. Which services fall inside it depends on CPT guidelines, the payer's policy, and what was actually performed.
Common examples include global codes for routine vaginal delivery (such as 59400) or cesarean delivery (such as 59510), as well as delivery-only, antepartum-only, and postpartum-only codes when a practice does not provide the full package. Always confirm current descriptors in the AMA CPT resources.
How Global Obstetric Billing Works
Billing Stage | What the Practice Should Review | Potential Revenue Risk |
Antepartum care | Visits, documentation, coverage | Missing or incorrectly reported services |
Delivery | Delivery details and applicable coding | Coding or documentation discrepancies |
Postpartum care | Included versus separately reportable services | Missed billing opportunities |
Claim submission | Patient, payer, codes, documentation | Denials and delays |
Payment review | Allowed amount and payer payment | Underpayments |
What may fall inside, and outside, the package
• Often inside: routine prenatal visits, the delivery, and routine postpartum care, subject to coding guidelines and payer policy.
• Often handled separately: services beyond routine care, such as medically necessary ultrasounds or testing, or visits for unrelated or complicated problems, when documentation supports them and payer rules allow.
• Varies by payer: how the first visit is reported, whether visits are itemized, and how a transfer of care is handled.
A patient who joins the practice late, changes insurance, or transfers out before delivery can change how services should be billed. That is why billing teams should review the whole pregnancy, not just the delivery date.
Where Maternity Revenue Leaks
Missed billable services Services outside the routine package go unreported. Tip: Review each visit for separately reportable care. | Incorrect package assumptions The wrong global or partial code is used for the situation. Tip: Match the code to the services your practice actually provided. | Eligibility problems Coverage changes during pregnancy are missed. Tip: Re-verify eligibility at key points. |
Documentation gaps Delivery or visit details are incomplete. Tip: Standardize delivery and visit documentation. | Coding discrepancies The claim does not match the record. Tip: Compare codes to documentation before submission. | Denied or underpaid claims Denials are resubmitted without finding the cause, and payments are not checked. Tip: Track denials by reason and compare payments to contract. |
Why claims get denied or underpaid
Common causes include inactive or changed coverage, claims that do not follow the payer's maternity policy, coding that does not match the delivery documentation, missing authorizations, and unsupported modifiers. Payers also differ on when to expect a global claim versus itemized services, so a process that works for one may fail for another. Payments that look correct on the remittance can still be below the contracted amount, which is why payment review matters.

How to Audit Global Maternity Claims
• Pull a sample of recent deliveries and compare the claim to the full record, from first visit to postpartum care.
• Check how each payer actually paid versus the contract or fee schedule.
• Sort denials by payer, provider, and reason, and look for repeat causes.
• Review aging maternity claims, since they can stay open for a long time.
• Repeat on a schedule so you can see whether fixes work.
When to Consider Professional Billing Support
Practices often look for help when denials repeat, maternity claims age, staff turnover leaves gaps, new providers or locations join, or nobody can say why payments are lower than expected. An experienced team can support coding review, eligibility, claim submission, denial management, A/R follow-up, payment review, and reporting. See how MedCloudMD works with practices.
