Is Your Global Maternity Billing Capturing Every Reimbursable Service?

Global maternity billing can make OB-GYN reimbursement look simpler than it actually is.

A practice may bill a global maternity package and assume that most pregnancy-related services are automatically covered under one payment. But global maternity billing has specific rules about what is included, what may be separately reportable, and what requires careful documentation.

That creates an important revenue-cycle question:

Is your practice capturing every service that is actually reimbursable, while correctly keeping bundled services inside the global package?

The answer requires more than checking whether the global maternity claim was accepted.

It requires reviewing the entire pregnancy episode, including antepartum services, delivery, postpartum care, additional procedures, high-risk services, diagnostics, payer requirements, and documentation.

What Does Global Maternity Billing Actually Include?

Global obstetric codes can cover a broad package of services.

For example, total obstetrical package codes can include antepartum care, delivery, and postpartum care. CMS guidance also identifies services that are included in certain maternity package codes and services that are not necessarily included, such as some ultrasounds, amniocentesis, special genetic screening, visits for unrelated conditions, and additional frequent visits associated with high-risk conditions.

That means the billing team cannot simply use a global code and assume every other service is automatically bundled.

At the same time, the opposite approach is also a problem.

The goal is not to separately bill every service provided during pregnancy.

The goal is to correctly identify:

• What belongs in the global package
• What is separately reportable
• What requires a modifier
• What requires additional documentation
• What depends on payer policy
• What should never be unbundled

This distinction is where revenue-cycle accuracy becomes important.

The First Revenue Question: What Was Actually Included?

The first step is to understand what the global maternity code covers for the specific patient and payer.

A practice should review whether the claim represents:

• Routine antepartum care
• Delivery
• Postpartum care
• Vaginal delivery
• Cesarean delivery
• Vaginal birth after previous cesarean
• High-risk pregnancy services
• Additional diagnostic services
• Procedures performed outside the routine maternity package
• Services unrelated to pregnancy

A global package is not a license to automatically bundle everything performed during the pregnancy.

Nor is it a reason to automatically bill every service separately.

The billing team needs to distinguish between the two.

How Global Maternity Billing Can Hide Revenue Leakage

Revenue leakage can occur when services that should be separately evaluated are simply absorbed into the global maternity claim.

For example, a practice may perform a service outside the standard global package but fail to identify it during charge review.

The claim may process successfully.

There may be no rejection.

There may be no denial.

But the practice may never receive reimbursement for the additional service.

This is why successful claim submission does not necessarily mean successful revenue capture.

The practice needs a process that reviews the entire pregnancy episode before final billing.

1. Ultrasound Services Need a Separate Review

Ultrasound services are one area where the billing team should understand the distinction between services included in the maternity package and services that may be separately reportable.

CMS's NCCI guidance states that total obstetrical packages include antepartum care, delivery, and postpartum care, but do not include certain other services, including ultrasound, amniocentesis, and special screening tests for genetic disorders.

That does not mean every ultrasound should automatically be billed separately.

The billing team still needs to review the specific service, documentation, payer requirements, and applicable coding rules.

The important point is that the billing workflow should not treat every pregnancy-related service as automatically bundled.

2. High-Risk Pregnancy Care Can Require Additional Review

Routine maternity care and high-risk pregnancy management are not always the same billing situation.

Additional visits may occur because of complications or high-risk conditions.

CMS guidance specifically notes that additional frequent visits due to high-risk conditions are not included in certain total obstetrical package codes.

This creates an important review point for OB-GYN practices.

If the provider is seeing a patient more frequently because of a documented high-risk condition, the billing team should determine whether the services are included in the global package or require separate reporting under the applicable rules.

The answer should come from the documentation and coding requirements, not from a blanket assumption.

3. Unrelated Visits Can Be Missed

Pregnant patients may also visit an OB-GYN practice for conditions that are unrelated to pregnancy.

A total obstetrical package does not automatically absorb every service provided during the pregnancy.

CMS guidance identifies visits for unrelated conditions as an example of services that are not included in certain total obstetrical packages.

This means the billing team should review the reason for the encounter.

If a service is unrelated to the pregnancy and separately reportable, it should not disappear simply because the patient is receiving global maternity care.

4. Delivery-Related Services Need Correct Bundling

The delivery itself creates another area where billing teams need to understand what is already included.

CMS NCCI guidance identifies several services that are included in certain obstetric delivery codes, including fetal monitoring during labor, episiotomy, and delivery of the placenta for the specified maternity package codes.

These services should not simply be added as separate charges because they appear on the operative or delivery documentation.

The billing team should understand the package rules and prevent inappropriate unbundling.

This is an important distinction:

Revenue capture does not mean billing everything separately.

It means billing every service correctly.

5. Postpartum Care Needs to Be Tracked Carefully

Global maternity billing can also create confusion around postpartum services.

When postpartum care is included in the global package, the practice should have a process to track those services without separately billing them inappropriately.

At the same time, the billing team should recognize when care falls outside the applicable global arrangement and requires separate evaluation.

Accurate tracking helps the practice understand what services have been delivered and what has already been included in the global payment.

The Difference Between Global Billing and Revenue Capture

Global billing is designed to combine related maternity services into a package.

Revenue capture is the process of making sure the practice receives all appropriate reimbursement for services that are actually separately reportable.

These are not contradictory concepts.

A strong maternity billing process should do both.

Global billing asks:

What services are included in the package?

Revenue capture asks:

What services fall outside the package and need separate consideration?

The billing team must answer both questions before the claim is finalized.

What Happens When the Billing Team Only Looks at the Global Code?

This is where hidden revenue loss can develop.

If the billing team sees a global maternity code and stops reviewing the patient's services, it may miss:

• Separately reportable diagnostic services
• Certain high-risk pregnancy services
• Unrelated visits
• Eligible additional procedures
• Services requiring specific modifiers
• Services that require separate payer review

The result can be a clean claim with incomplete revenue capture.

For a deeper discussion of this issue, review global maternity billing and hidden revenue loss.

Why Cash Flow Can Suffer Even When Global Claims Are Paid

A practice may have a high percentage of paid global maternity claims and still experience cash-flow pressure.

Why?

Because the problem may not be whether the global claim was paid.

The problem may be whether all appropriate revenue associated with the pregnancy episode was captured before the claim was finalized.

If separately reportable services are consistently missed, the practice can experience cumulative revenue leakage.

Build a Pregnancy-Episode Billing Review

Instead of reviewing the delivery claim alone, an OB-GYN practice can review the complete pregnancy episode.

A practical workflow can include:

Step 1: Identify the Global Maternity Code

Determine which global maternity code applies based on the delivery and documented care.

Step 2: Review Antepartum Services

Confirm which routine services belong inside the global package and identify services that require separate review.

Step 3: Review Diagnostic Services

Look at ultrasounds, genetic screening, amniocentesis, and other diagnostic services.

Step 4: Review High-Risk Services

Determine whether additional visits or services were provided because of documented high-risk conditions.

Step 5: Review Unrelated Encounters

Identify services that were unrelated to pregnancy and determine whether separate billing applies.

Step 6: Review Delivery Services

Confirm that services included in the global delivery code are not incorrectly billed separately.

Step 7: Review Postpartum Care

Confirm that included postpartum services are handled correctly and identify any services that require separate evaluation.

Step 8: Compare Expected and Actual Reimbursement

Finally, compare what the practice expected to collect with what the payer actually paid.

This final step is important because claim acceptance does not necessarily prove complete revenue capture.

Documentation Is the Foundation of Separate Billing

The billing team cannot identify every potentially reimbursable service without adequate documentation.

The medical record should support:

• The reason for the encounter
• The diagnosis
• The services performed
• Medical necessity when applicable
• The relationship between the service and pregnancy
• High-risk conditions when relevant
• Procedures performed
• Timing of services
• Any circumstances requiring separate reporting

The billing team should then compare the documentation against the applicable coding and payer requirements.

This protects the practice from both underbilling and inappropriate unbundling.

Payer Rules Matter

Medicare rules provide one framework, but OB-GYN practices often work with multiple commercial payers and Medicare Advantage plans.

Payer contracts and policies can differ.

Therefore, a billing process should not assume that one global maternity billing rule applies identically to every payer.

The practice should monitor:

• Payer-specific global maternity policies
• Modifier requirements
• Claim edits
• Coverage policies
• Authorization requirements
• Reimbursement changes
• Denial patterns

A recurring payer denial can reveal that the practice's billing workflow needs a more specific payer-level review.

What Should an OB-GYN Billing Partner Report?

A useful monthly maternity billing report should go beyond the number of global claims submitted.

Consider tracking:

Metric	What It Shows
Global Maternity Claims	Volume of global episodes
Global Claims Paid	Payment performance
Denial Rate	Claims requiring additional work
A/R Days	Speed of reimbursement
A/R Over 90 Days	Aging revenue
Separate-Service Revenue	Revenue outside global packages
Missed-Charge Findings	Potential revenue leakage
Payer Variance	Differences in expected and actual reimbursement
High-Risk Billing Review	Additional services requiring review
Postpartum Billing Review	Correct handling of included and separate services

This gives practice leadership a clearer view of whether the global maternity billing process is actually capturing available revenue.

Questions to Ask Your OB-GYN Billing Company

If you are evaluating your current billing partner, ask:

"How do you identify services outside the global package?"

The billing company should have a defined review process.

"How do you identify high-risk pregnancy services?"

Ask whether the team reviews documentation and encounter patterns rather than automatically bundling every pregnancy-related visit.

"How do you handle ultrasound and diagnostic services?"

The answer should explain how the billing team determines whether a service is included or separately reportable.

"How do you prevent inappropriate unbundling?"

A good process needs to protect against both missed revenue and incorrect separate billing.

"Do you report revenue leakage from global maternity claims?"

Ask whether the vendor identifies recurring missed-charge patterns.

"Can you show payer-level maternity performance?"

This can reveal whether a specific payer is creating recurring billing or reimbursement problems.

When Should an OB-GYN Practice Review Its Billing Partner?

A practice may want to review its maternity billing workflow when it sees recurring signs such as:

• Global maternity payments below expectations
• Increasing A/R
• Repeated payer-specific denials
• Unexplained reimbursement differences
• Missed charges identified during audits
• High-risk visits consistently being bundled without review
• Poor visibility into separately reportable services
• Lack of procedure-level reporting
• No clear explanation of global billing methodology

The goal is not automatically to change vendors.

The first step is to determine whether the issue is related to coding, documentation, payer policy, workflow, or vendor performance.

Choosing an OB-GYN Billing Partner

OB-GYN billing requires more than general medical billing knowledge.

A specialized billing partner should understand global maternity billing, delivery coding, postpartum care, high-risk pregnancy services, payer requirements, denials, A/R management, and reimbursement analysis.

If your practice is comparing vendors, review best OBGYN billing companies in 2026 and evaluate each option based on specialty experience, reporting capabilities, coding expertise, and the specific needs of your practice.

The important point is to compare capabilities rather than selecting a vendor based only on a single performance metric.

Final Takeaway

Global maternity billing is designed to simplify reimbursement for defined obstetric services, but it does not mean every service provided during pregnancy belongs inside one global payment.

CMS guidance makes clear that global obstetric packages include specified antepartum, delivery, and postpartum services, while certain services and circumstances can fall outside the package.

For an OB-GYN practice, the real revenue-cycle challenge is finding the balance between:

Correct bundling + Complete revenue capture + Strong documentation + Payer-specific billing accuracy

A practice should regularly review its maternity episodes to determine whether separately reportable services are being captured appropriately and whether bundled services are being billed correctly.

The goal is not to bill more.

The goal is to bill correctly for everything the practice is entitled to report and collect.

Frequently Asked Questions

Does global maternity billing include every pregnancy-related service?

No. Global obstetric packages include specific antepartum, delivery, and postpartum services. Certain services, such as some ultrasounds, genetic screening, amniocentesis, unrelated visits, and additional frequent visits for high-risk conditions, may fall outside the package depending on the circumstances and applicable rules.

Can an OB-GYN practice separately bill ultrasound during global maternity care?

Some ultrasound services may be separately reportable, but practices should review the specific service, documentation, payer policy, and applicable coding rules rather than assuming that every ultrasound is separately payable.

Are all delivery-related services separately billable?

No. CMS NCCI guidance identifies certain services, including fetal monitoring during labor, episiotomy, and delivery of the placenta, as included in specified obstetric package codes.

Can high-risk pregnancy visits be billed separately?

Additional frequent visits due to high-risk conditions may fall outside certain total obstetrical packages, but the practice must review the documentation, coding requirements, and payer rules for the specific situation.

How can an OB-GYN practice identify hidden maternity revenue loss?

Review the complete pregnancy episode, compare services against the global package, identify separately reportable services, check payer-specific rules, review missed charges, and compare expected reimbursement with actual payment.

What should an OB-GYN billing partner report?

At minimum, practices should consider tracking global claims, payment rates, denials, A/R aging, payer variance, separately reported service revenue, missed-charge findings, and high-risk maternity billing patterns.
