A breakdown of how global maternity billing works, when it applies, and where practices lose revenue by misapplying the package.
Global maternity billing bundles the full arc of a pregnancy — antepartum visits, delivery, and postpartum care — into a single claim under one CPT code. On paper it looks simple. In practice, it's one of the most misapplied billing concepts in OB/GYN care, and misapplying it is a quiet, recurring source of lost revenue.
What the Global Package Actually Covers
The global maternity package typically includes routine antepartum visits (usually defined as more than one but fewer than a set threshold), the delivery itself, and postpartum care through six weeks. Services outside that window — a problem visit unrelated to the pregnancy, an unscheduled ultrasound for a specific complaint, or care delivered by a different provider group — should usually be billed separately, not folded into the global fee.
Where Practices Lose Money
The most common mistake isn't billing the wrong code — it's billing everything as "part of the package" when it isn't. Complications like hyperemesis, gestational diabetes management, or a change in provider mid-pregnancy often qualify for itemized billing instead. Practices that don't distinguish between global and itemized scenarios consistently under-bill without realizing it.
Our detailed breakdown of [itemized vs. global maternity billing](/blog/itemized-vs-global-maternity-billing) walks through exactly when each approach applies.
Getting the Diagnosis Coding Right
Global billing accuracy also depends on correct use of obstetric diagnosis codes. If you're not confident your ICD-10 O-code assignments line up with what the payer expects to see alongside a global claim, our [ICD-10 O-codes guide](/resources/icd10-o-codes) is a good reference point.
Key Takeaways
- ›Global billing applies to routine, uncomplicated pregnancy care only
- ›Complications and provider changes usually require itemized billing
- ›Documentation must clearly support which model applies to each patient
