OB/GYN Billing — Global OB Package, Gynecology Procedures, Every Code Done Right

OB/GYN billing manages two completely different billing worlds in one practice — the global obstetric package with its antepartum, delivery, and postpartum components, and the high-procedure gynecology side with its own code families, prior auth requirements, and documentation rules. Netix handles both with equal precision so your physicians focus on patients, not billing complexity.

THE PROBLEM

Why OB/GYN Practices Lose Revenue Across Both Sides of the Practice

OB/GYN billing errors come from two directions simultaneously — obstetric package complexity on one side and gynecology procedure coding on the other. Here is where the losses happen most consistently:

Global OB package billing is the most misunderstood concept in women’s health billing

The global obstetric package (59400 vaginal delivery, 59510 cesarean) bundles antepartum care visits, the delivery, and postpartum care into a single payment. Most practices understand this in theory — but make systematic errors in practice. Patients who transfer in mid-pregnancy, deliver preterm, experience complications, or transfer care to another physician require component billing instead of global — and practices routinely miss the switch, either overbilling the global when it does not apply or underbilling component codes when they do.

Antepartum care component billing is consistently miscoded

When a patient does not complete the full antepartum visit schedule (fewer than 4 visits = 59425, 4 or more visits = 59426) or when care is split between providers, antepartum visits must be billed separately. The number of qualifying antepartum visits is frequently miscounted and the component codes are frequently wrong.

Postpartum visit billing is routinely missed after C-sections

The postpartum visit is included in the global package for vaginal deliveries (59400) and C-sections (59510). But when the global package is not billed — because the practice did not do the delivery, or the patient transferred — the postpartum visit (59430) is separately billable and is missed on a significant percentage of qualifying encounters.

Gynecology procedure coding requires the same precision as surgical billing

Hysteroscopy, laparoscopy, colposcopy, LEEP, endometrial ablation, IUD insertion and removal, colposcopy-directed biopsy — each has its own CPT family with bundling rules, modifier requirements, and medical necessity documentation standards. Vague operative notes, wrong approach coding (open vs laparoscopic), and missing modifier 51 on multiple procedure days all cost revenue.

Preventive OB/GYN visit billing is mishandled across the board

Annual gynecologic exams are preventive visits — billed as 99385–99397 by patient age, not as problem-focused E&M. When a problem is addressed same-day, modifier 25 applies to the separately billed E&M. Most practices either bill everything as E&M or miss the modifier 25 on same-day problem visits — leaving preventive visit reimbursement and same-day E&M reimbursement both at risk.

Infertility billing requires a completely separate approach

Infertility services — IUI, IVF, ovulation induction — have their own CPT codes, their own coverage rules (which vary dramatically by state and plan), and their own prior authorization requirements. Billing infertility services under standard gynecology codes or without verifying coverage first is one of the most consistent denial sources in OB/GYN.

OUR OB/GYN BILLING SERVICES

What Netix Handles for OB/GYN Practices

Global OB Package Billing

Correct global code selection (59400 vaginal, 59510 cesarean, 59610 VBAC, 59618 attempted VBAC → cesarean) with continuous monitoring of each patient’s care trajectory — switching to component billing the moment a patient transfers, delivers preterm, or experiences complications that break the global package.

Antepartum Care Component Billing

Antepartum visit counting per patient, correct component code selection (59425 for fewer than 4 visits, 59426 for 4 or more), and split-care billing when antepartum care is shared between providers — with each provider billing only the visits they performed.

Delivery Billing

Vaginal delivery (59400–59410), cesarean (59510–59515), VBAC (59610–59614), attempted VBAC to cesarean (59618–59622) — correct global vs component selection, attending vs co-surgeon billing, and delivery complication coding when applicable.

Postpartum Care Billing

Postpartum visit (59430) identified and billed on every case where it is separately payable — not included in an incorrectly applied global package, and not missed when the global does not apply.

High-Risk OB Billing

Cerclage (57700, 59320), amniocentesis (59000), fetal non-stress test (59025), biophysical profile (76818–76819), external cephalic version (59412) — high-risk OB procedures billed correctly alongside or separately from the global package depending on timing and payer rules.

Gynecology Procedure Billing

Hysteroscopy (58555–58565), laparoscopy (58660–58679), colposcopy (57452–57461), LEEP/LLETZ (57460–57461), endometrial ablation (58353–58356), myomectomy (58140–58146, 58545–58546) — correct approach coding, bundling rules, and modifier 51 on multiple procedure days.

IUD & Contraceptive Device Billing

IUD insertion (58300), IUD removal (58301), implant insertion (11981), implant removal (11982), implant removal and reinsertion (11983) — device supply billing separated from insertion procedure, and payer-specific coverage verification before the visit.

Infertility Billing

IUI (58321–58322), ovulation induction monitoring, IVF-related services — with coverage verification per plan (infertility coverage varies dramatically), prior auth management for covered services, and patient responsibility calculation for non-covered services billed directly.

Preventive Visit & Annual Exam Billing

Correct preventive visit code selection by age (99384–99387 new, 99394–99397 established), modifier 25 applied when a problem is addressed same-day, and pelvic exam bundling rules applied correctly.

Colposcopy & Cervical Procedure Billing

Colposcopy with biopsy (57454–57455), ECC (57456), LEEP (57460–57461) — number of biopsies documented and coded, cervical procedure bundling rules applied, and prior auth verified for LEEP when required.

Prior Authorization Management

Hysterectomy, laparoscopic procedures, infertility treatments, and certain imaging studies — auth obtained before scheduling, clinical documentation prepared for medical necessity review, and auth tracked to approval.

Denial Management — OB/GYN Specific

Global package disputes, antepartum component denials, infertility coverage denials, medical necessity challenges on gynecology procedures, and cosmetic vs medical distinction on certain procedures — appealed with OB/GYN-specific clinical documentation.

OB/GYN Authorization Support

Certain OB/GYN procedures, infertility treatments, and diagnostic services may require approval before they are scheduled or performed. Managing required approvals in advance helps practices submit the necessary clinical documentation, track authorization status, and reduce avoidable delays in patient care or reimbursement.

GLOBAL OB PACKAGE EXPLAINED

The Global OB Package — What It Includes and When It Breaks

The global obstetric package is the foundation of OB billing — and the most common source of billing errors in women’s health practices.

What the global package includes:
The global OB fee covers all antepartum visits (after the initial OB visit), the delivery (vaginal or cesarean), and the postpartum visit — bundled into a single payment. The initial OB visit is billed separately as an E&M on the first prenatal encounter.

Global package codes:

59400: Vaginal delivery including antepartum and postpartum care
59510: Cesarean delivery including antepartum and postpartum care
59610: VBAC including antepartum and postpartum care
59618: Attempted VBAC → cesarean including antepartum and postpartum care

When the global package breaks — and component billing begins:

Patient transfers in

Patient seen by another provider for antepartum care and transfers to your practice for delivery only — bill delivery only codes (59409 vaginal, 59514 cesarean), not the global.

Patient transfers out

Your practice provides antepartum care but another provider delivers — bill antepartum component codes (59425 or 59426), not the global.

Preterm delivery

Patient delivers before completing the standard antepartum visit schedule — bill completed antepartum visits as a component plus the delivery.

Complications

Certain high-risk procedures and complications during pregnancy are separately billable alongside or instead of the global package — cerclage, amniocentesis, fetal monitoring, and others.

What this costs practices

Billing the global code when only a component was provided = overbilling and potential recoupment. Missing the switch to component billing when a patient transfers = underbilling and lost revenue. Both directions cost money — and both are preventable with proper tracking.

What we do

Per-patient global package tracking from first prenatal visit through postpartum — flagging every patient whose care trajectory changes and switching billing to the correct approach before the claim goes out.

FAQ

OB/GYN Billing Questions

When should we bill the global OB package vs component codes?

Bill the global package when your practice provides all three components — antepartum care, delivery, and postpartum visit. Switch to component billing when any component is provided by a different physician or when the patient transfers care mid-pregnancy. Per-patient tracking from first prenatal visit through delivery is the only reliable way to get this right.

How do we bill when a patient transfers to us just for delivery?

Bill the delivery-only code — 59409 for vaginal delivery or 59514 for cesarean — not the global package. The global includes antepartum care that another provider delivered and was paid for. Billing the global when you only did the delivery is an overbilling error with recoupment risk.

Are high-risk OB procedures separately billable alongside the global package?

Some are and some are not — it depends on the procedure and the payer. Fetal non-stress tests (59025), biophysical profiles (76818–76819), amniocentesis (59000), and cerclage (59320) are generally separately billable. Routine antepartum monitoring is included in the global. The distinction matters and varies by payer.

We do a lot of IUD insertions. How should the device be billed?

The IUD device supply (J7300 for Mirena/Kyleena, J7301 for Liletta, J7296 for Paragard) is billed separately from the insertion procedure (58300). The supply billing goes to the insurance carrier under the J-code; the procedure is billed with the CPT code. Many practices miss the device billing entirely or bill it incorrectly.

Can you handle infertility billing specifically?

Yes — with coverage verification first, since infertility coverage varies dramatically by state mandate and individual plan. We verify covered services, obtain prior auth where required, and separate covered from non-covered infertility services so patient responsibility is calculated correctly before treatment begins.

What makes OB/GYN billing harder than general medical billing?

The global OB package with its component tracking complexity, the obstetric-to-gynecologic patient transition (same patient, different billing rules depending on pregnancy status), infertility coverage variations, and the high-procedure gynecology side with its own bundling and modifier rules. A general biller applies office visit logic to a specialty that requires package tracking — and that approach costs money on every delivery.
