TWO REVENUE CYCLES. ONE PRACTICE.

OB/GYN Billing Services for Both Sides of Women's Health — Because Obstetrics and Gynecology Follow Two Completely Different Rulebooks

Your Practice Bills Two Specialties at Once. Most Billing Companies Only Understand One.

OB/GYN is really two revenue cycles under one roof. Obstetrics runs on the global maternity package — nine months of care bundled into a single code you bill months after the pregnancy begins. Gynecology runs the opposite way — surgeries, office procedures, and preventive visits billed individually, each with its own rules. A billing team that knows one side and fumbles the other is quietly costing you thousands per patient.

Our OB/GYN billing services are built for both. We manage the global maternity package and the split-care scenarios that trip everyone up, and we code your gynecologic surgeries, well-woman visits, and contraception devices accurately — so every side of your practice gets paid in full.

THE CORE OB/GYN BILLING SPLIT

OB/GYN Isn't One Specialty to Bill — It's Two, With Two Different Rulebooks

Understanding this split is the whole key to OB/GYN billing, and it's exactly where generalist billers fall down.

01
OBSTETRICS

The obstetrics side is bundled.

Routine pregnancy care — the antepartum visits, the delivery, the postpartum checkup — is combined into a single global maternity code and reimbursed as one payment. Unlike a surgical global period measured in days, the obstetric package covers the entire pregnancy regardless of length, and you don't bill it until after delivery. That means your practice carries nine months of care before it collects, and any error in how the package is documented or split puts the whole payment at risk.

ANTEDELIVERYPOST
ONE PRACTICE TWO OPPOSITE SYSTEMS
OB/GYN
02
GYNECOLOGY

The gynecology side is itemized.

Well-woman exams, Pap smears, colposcopies, biopsies, hysterectomies, IUD placements — each is billed individually, with its own modifiers, global periods, device codes, and medical-necessity rules. It behaves like a surgical-and-office specialty, nothing like the maternity bundle next to it.

Visits Procedures Devices Surgery
THE SEAM IS WHERE REVENUE LEAKS One practice, two opposite billing systems. Master both and the revenue is strong. Miss the seams between them — and generalist billers always do — and money leaks from both sides at once. That's the gap our obstetrics and gynecology billing expertise is built to close.
THE GLOBAL MATERNITY CONTROL ROOM

The Global Maternity Package: Medicine's Most Unusual Billing Rule — and Where Practices Lose Thousands

The global maternity package is the foundation of obstetric revenue, and it's also the single biggest source of OB billing losses. Here's why.

01
FULL COURSE OF CARE

Four global codes assume a complete maternity journey.

The four global codes each assume a full course of care — a set number of antepartum visits, the delivery, and the postpartum visit — bundled into one payment.

ANTEDELIVERYPOSTONE PAYMENT
THE WOMEN'S HEALTH REVENUE LEAK BOARD

What Weak OB/GYN Billing Costs a Practice Every Year

01 MATERNITY

Global package downcodes

An undocumented antepartum visit count drops a full global claim to an antepartum-only code — hundreds lost per delivery

02 SPLIT CARE

Split-care billing errors

Multiple providers billing global for the same pregnancy, or global billed for partial care — denials and recoupments

03 ULTRASOUND

Uncaptured obstetric ultrasounds

Separately billable scans left off claims, or denied for missing the gestational-week diagnosis

04 HIGH-RISK OB

VBAC and co-management mismatches

Claims silently repriced or denied as duplicates, often caught only after 90 days

05 GYNECOLOGY

Undercoded gynecologic surgery

Hysterectomies and procedures billed below the complexity performed

06 CONTRACEPTION

IUD and implant device gaps

The contraceptive device not billed alongside the insertion, forfeiting real revenue

07 PREVENTIVE + PROBLEM

Well-woman plus problem visits

Preventive and problem services on the same day not split-billed with the right modifier

6+
SIX-FIGURE ANNUAL EXPOSURE For a high-volume women's health practice, these patterns quietly add up to six figures a year — much of it downcoded rather than denied, so it never even shows up on an A/R aging report.
MAJOR MATERNITY CODE SHIFT 2027 Preparation starts now
A MAJOR CHANGE IS COMING

A Major Change Is Coming in 2027 — and the Practices That Prepare Now Win

Here's something most billing companies aren't telling their OB/GYN clients: the global maternity codes are being phased out. Beginning January 1, 2027, a new set of maternity CPT codes replaces most of the current global package structure, with antepartum care billed through individual visit codes and separate labor and delivery codes. It's the most significant change to OB billing in decades.

The practices that come through it cleanly are the ones that start adjusting in 2026 — testing the new workflows with their top payers, updating documentation to support visit-by-visit billing, and applying the recommended transition modifier on maternity visits ahead of the deadline. The practices that wait risk weeks of claim rejections when the switch happens.

We're already preparing our OB/GYN clients for this transition, so your revenue cycle doesn't skip a beat when the codes change. Partnering with a specialist now isn't just about this year's collections — it's about being ready for the biggest maternity billing shift in a generation.

TWO SPECIALTIES + SHARED INFRASTRUCTURE

The OB/GYN Billing Services We Provide

Because your practice bills two specialties, we've built our services for both — plus the shared infrastructure that supports them.

OB
ON THE OBSTETRICS SIDE

Global, component, ultrasound, and high-risk revenue

01GLOBAL PACKAGE

Global Maternity Package Management.

We track antepartum visit counts, document them against payer requirements, capture the postpartum visit, and bill the correct global code — so your maternity claims reimburse at the full global rate instead of getting downcoded under payer audit.

02COMPONENT CARE

Split & Component Care Billing.

When a patient transfers, delivers elsewhere, or you cover a delivery, we bill only your portion with the correct antepartum-only, delivery-only, or postpartum code — and document the care transition so both providers get paid and neither claim denies.

03ULTRASOUND CAPTURE

Obstetric Ultrasound Billing.

We bill your pregnancy ultrasounds separately from the global package, apply the professional and technical split correctly, include the required gestational-week diagnosis, and track each payer's coverage limits so scans get paid instead of denied.

04COMPLEX OB

High-Risk, VBAC & Complication Coding.

We code high-risk pregnancies, multiple gestations, VBAC and cesarean deliveries, co-management arrangements, and separately billable complications and procedures accurately — capturing the additional revenue these complex cases legitimately earn.

05FUTURE READINESS

2027 Transition Readiness.

We're preparing your practice for the new maternity code structure now, so the shift from global packages to individual visit and delivery codes is seamless when it takes effect.

GYN
ON THE GYNECOLOGY SIDE

Preventive, procedural, surgical, and device revenue

06PREVENTIVE + PROBLEM

Well-Woman & Preventive Visit Billing.

We code annual exams, Pap collection, and screening correctly, and split-bill a preventive visit and a same-day problem visit with the right modifier — so covered preventive care processes cleanly and you're paid for the problem work too.

07SURGICAL COMPLEXITY

Gynecologic Surgery & Global Period Management.

For hysterectomies, laparoscopies, myomectomies, and other procedures, we code to the complexity performed, manage the surgical global periods so post-op visits aren't billed by mistake, and apply the increased-complexity modifiers when the operative note supports them.

08IN-OFFICE PROCEDURES

In-Office Procedure Billing.

Colposcopies, cervical and endometrial biopsies, LEEP, hysteroscopy, and ablation — coded accurately with the right modifiers so these in-office services are captured and paid.

09DEVICE REVENUE

IUD, Implant & Contraception Device Billing.

We bill the contraceptive device alongside the insertion procedure — the piece practices most often miss — so IUDs, implants, and injectables generate the full revenue they should, not just the placement fee.

10MEDICAID COMPLIANCE

Sterilization & Medicaid Compliance.

Tubal ligation and other sterilization services carry strict, state-specific Medicaid consent-form requirements. We make sure the documentation meets them, so these claims don't deny on a technicality.

ALL
ACROSS BOTH SIDES

Shared infrastructure that keeps both revenue cycles moving

11AUTHORIZATION

Prior Authorization Management.

We handle authorizations for surgeries, advanced imaging, additional ultrasounds, and high-cost services, and keep them active so high-value claims don't die at billing.

12DENIAL RECOVERY

Denial Management & Appeals.

Our denial management team works every denied OB/GYN claim to its root cause — visit counts, split care, modifiers, device codes, medical necessity — and appeals what's owed, so the same denial stops repeating.

13PAYER ACCESS

Provider Credentialing & Enrollment.

We handle credentialing and enrollment for your OB/GYNs, midwives, and advanced-practice providers across every payer, starting at hire. Reliable OB/GYN credentialing keeps revenue flowing from a provider's first day.

14PERFORMANCE VISIBILITY

Reporting & Analytics.

Clear monthly reporting on clean-claim rate, denial rate, global-package capture, gynecologic surgical revenue, days in A/R, and revenue by provider — so you always know where your practice stands.

COMPLETE OB/GYN RCM Together, these make up complete OB/GYN revenue cycle management — one team handling both revenue cycles under your roof.

OB/GYN BILLING QUESTIONS

OB/GYN Billing Questions, Answered

The global maternity package bundles routine pregnancy care — antepartum visits, the delivery, and postpartum care — into a single CPT code (such as 59400 for vaginal delivery or 59510 for cesarean) reimbursed as one payment. Unlike a surgical global period measured in days, it covers the entire pregnancy regardless of length, and it's billed after delivery. The catch is that payers now audit the antepartum visit count before paying, so incomplete documentation can drop a full global claim to a lower-paying antepartum-only code. We track and document the visit counts so you're paid the full global rate.
