How to Bill Global Obstetric Care Correctly

A maternity claim can look clean at the time of delivery and still fail months later because the prenatal record, benefit verification, or provider enrollment was not handled correctly. To bill global obstetric care accurately, your practice needs to know what the payer considers part of the package, when care must be split into components, and how your documentation supports the claim.

For midwives, birth centers, and OB/GYN practices, global billing can reduce claim volume and simplify patient financial conversations. But it is not a one-size-fits-all shortcut. Payer policies, network status, transfer-of-care timing, and the actual services provided all affect whether a global claim is appropriate and payable.

What global obstetric billing includes

A global obstetric package generally combines routine antepartum care, delivery, and postpartum care into one CPT code. For example, CPT 59400 is commonly used for routine vaginal delivery global care, while CPT 59510 is commonly used for routine cesarean delivery global care. Other global codes apply when the patient has a prior cesarean delivery and receives trial of labor or repeat cesarean care.

The package usually includes routine prenatal visits, the delivery service, and postpartum care. It does not automatically include every service that happens during pregnancy. Problem-focused visits, separately identifiable procedures, certain tests, ultrasounds, treatment for complications, and unrelated medical services may be billed separately when documentation and payer policy support doing so.

That distinction matters. A routine prenatal visit for an uncomplicated pregnancy belongs in the global package. A medically necessary visit to evaluate a complication may be separately reportable when it is clearly documented, coded correctly, and not bundled by the payer. Submitting separate routine E/M claims during a global episode is a common cause of denials and recoupments.

When to bill global obstetric care

Global billing is typically appropriate when the same billing provider or practice furnishes the required prenatal care, performs the delivery, and provides postpartum care. The exact number of required prenatal visits is not universal. Your payer contract and policy should guide the workflow, which is why verification of benefits should happen early, not when the patient is in labor.

Before choosing a global code, confirm the patient’s maternity benefits, deductible and coinsurance responsibilities, network rules, authorization requirements, and whether the payer has any special rules for midwife-attended births or birth center services. A detailed VOB should also identify whether the plan has separate professional and facility benefits.

For patients who receive a full course of routine care with your practice, the global claim is generally submitted after delivery. Waiting until delivery does not mean waiting to do the billing work. Demographics, eligibility, authorization details, referral requirements, coordination of benefits, and provider credentialing should be checked well before the claim is due.

Global billing is not always the right choice

Split billing may be necessary when the patient transfers into or out of care, changes insurance, moves, delivers with another provider, or receives only a portion of her maternity care from your practice. In those cases, antepartum care codes may apply based on the number of visits completed.

For example, CPT 59425 is commonly used for four to six antepartum visits, while CPT 59426 is commonly used for seven or more antepartum visits. When fewer than four antepartum visits were provided, individual office visit coding may be appropriate. Delivery-only and postpartum-only codes may also be needed when your practice did not provide the complete global package.

Do not assume that a transfer automatically means the original practice can bill globally. Review the dates of service, number of visits, delivery record, payer policy, and any care shared between clinicians. This is an area where a maternity-focused billing review can prevent lost revenue and avoidable compliance risk.

The documentation that protects payment

Clean maternity claims start with clinical documentation that matches the billing structure. The chart should make it easy to see the pregnancy episode, prenatal visit count, provider involvement, complications addressed, delivery details, and postpartum follow-up.

For a global claim, maintain clear records of routine prenatal care and postpartum services included in the package. For services billed outside the package, document why the service was medically necessary and distinct from routine obstetric management. Vague notes can leave your claim vulnerable to a payer request, denial, or post-payment audit.

Delivery documentation needs particular attention. The record should identify the delivery type, clinician performing the service, location, relevant complications, and any procedures performed. Facility billing and professional billing are not interchangeable. A birth center may have a facility claim workflow that is separate from the midwife's professional claim, and each claim must reflect the contracted entity, payer requirements, and correct identifiers.

Credentialing can also determine whether a claim pays. A correctly coded global claim may still deny if the rendering provider is not enrolled with the payer, is not linked to the group correctly, or is not credentialed for the billed place of service. Resolve those issues before delivery whenever possible. Correcting enrollment after the fact can delay payment and create patient balance problems.

Common global maternity billing mistakes

The most expensive errors usually occur before claim submission. A patient may appear active at intake but have a plan with a narrow network, a maternity carve-out, or a benefit change scheduled for the new plan year. If the VOB is incomplete, the practice may build a payment plan around benefits that do not exist.

Another common mistake is billing the wrong provider or entity. This can happen when a patient sees multiple midwives, collaborates with an OB/GYN, transfers between offices, or delivers in a hospital after planning a birth center birth. Your billing team needs a defined process for tracking who provided prenatal care, who performed the delivery, and who completed postpartum care.

Incorrect use of modifiers can create another layer of problems. Modifiers should not be added simply to force a claim through. They need to reflect the actual service and comply with payer rules. The same caution applies to diagnosis coding. Pregnancy-related diagnoses should accurately show trimester, supervision status, and any documented complications without overstating risk.

Finally, do not close the episode once the delivery claim is submitted. Postpartum care is part of many global packages, and payment posting should confirm that the payer adjudicated the claim as expected. If the claim is underpaid or denied, review the remittance advice against the contract, benefit verification, code selection, and medical record before sending a generic appeal.

Build a workflow that prevents denials

The strongest global billing workflow begins at intake and continues through final payment. Start each episode with a thorough VOB and an accurate patient estimate. Track prenatal visits in the EMR so the billing team can identify whether global billing, antepartum-only billing, or individual visit billing is appropriate.

Create a handoff process for transfers, changes in insurance, high-risk complications, hospital deliveries, and postpartum care performed outside your practice. These are not rare exceptions in maternity care. They are predictable billing events that need a documented workflow.

Your team should also reconcile delivery logs against submitted claims. A delivery log can reveal missing claims, incorrect delivery codes, unbilled postpartum-only services, and claims still waiting on records or payer review. For practices managing both professional and facility billing, reconciliation is especially valuable because an issue on one side of the claim does not always appear on the other.

As maternity reimbursement rules and payer expectations continue to evolve, practices should review their templates, EMR configuration, fee schedules, and billing policies before changes take effect. Preparation for upcoming maternity billing transitions is not just a compliance task. It protects cash flow, reduces staff rework, and gives patients clearer financial expectations.

Global obstetric billing works best when it is treated as an episode-of-care process, not a single claim sent after delivery. A specialized billing partner such as Best Way Medical Billing can help practices review VOBs, claim workflows, denials, and reimbursement patterns before small gaps turn into a larger revenue problem. The right process gives your clinicians more room to focus on care while your practice stays ready to be paid for the work it performs.
