Where OB-GYN billing breaks
Five revenue leaks hiding inside your maternity workflow
Global package mid-pregnancy unbundling
A patient switches insurance at 28 weeks and the practice bills 59400 globally to the new payer. The claim rejects because the new carrier didn't cover the first two trimesters of antepartum.
Modifier 25 same-day visit auto-denials
Payers auto-deny problem E/M codes billed alongside a well-woman exam in 2026 unless documentation clearly separates the two visits with distinct clinical histories and ICD-10 pointers.
LARC device costs written off on claims
An IUD or Nexplanon insertion billed with the wrong J-code or a missing J-code means the practice absorbs the full device cost — and that's not a rounding error.
Fetal surveillance billed inside bundles
Non-stress tests (59025) and biophysical profiles (76818) performed on high-risk pregnancies are billable outside the global package. Most practices leave them off because they assume the bundle covers it.
Colposcopy and LEEP bundling rejections
Diagnostic colposcopy (57454) bundles into LEEP cone biopsy (57522) when both happen in the same encounter. Billing them separately without recognizing the NCCI edit pair triggers an instant rejection.
Five-Phase Operating System
How the Revenue Control Framework runs for OB-GYN
OB-GYN billing breaks across three timelines at once: a 9-month global maternity cycle, same-day preventive-plus-problem visits, and high-cost device insertions that need exact J-code pairing. The Revenue Control Framework catches each one at a different phase, before the claim goes out.
Onboarding and payer setup
We pull your payer contracts, load every active patient's EDD and global package status, and connect to your women's health EHR (ModMed EMA, Epic Stork, or whichever system you run) within 5 days. By day one, every maternity patient's trimester position and visit count is in our tracking system.
Eligibility and pre-auth prep
Before every initial OB visit, we verify maternity benefits, calculate deductible exposure, and flag global package exclusions by payer. We run the same pre-visit clearance workflow that drives collections for our family practice billing partners and other high-referral specialties.
Coding and charge capture
Certified coders assigned to your practice review every prenatal flowsheet, delivery record, and surgical note for global package accuracy, Modifier 25 same-day logic, and LARC device J-code pairing through our medical coding services. Claims get scrubbed against NCCI edit pairs before submission.
Denial resolution and appeals
Denied claims get categorized by root cause within 48 hours. CO-4 Modifier 25 denials, CO-97 bundling rejections, and CO-16 global package documentation gaps each follow a separate AR recovery path because batching OB-GYN denials into one queue doesn't work.
Reporting and revenue tracking
Live dashboards track collections by service line, denial rates by payer, and maternity pipeline value by trimester. You'll see which revenue sits in active global packages and which claims need intervention before the month closes.
OB-GYN Coding Reference
CPT and modifier codes we bill every cycle
Every code here comes from OB-GYN encounters we bill weekly. We've verified each against AMA CPT 2026.
| Code | Description | Packaging and billing rule |
|---|---|---|
59400 / 59510 | Global vaginal delivery / global cesarean delivery | Covers ~13 antepartum visits + delivery + 6-week postpartum. Billed after delivery. Don't unbundle when one payer covers full term. |
59425 / 59426 | Antepartum care only: 4-6 visits / 7+ visits | Billed when patient switches insurance, relocates, or changes provider mid-pregnancy. 1-3 visits bill as E/M (99212-99215). |
59409 / 59514 | Vaginal delivery only / cesarean delivery only | Billed when antepartum was rendered by another provider. Pair with postpartum 59430 if your practice handles both. |
59025 / 76818 | Non-stress test (NST) / biophysical profile (BPP) | Billed per session outside the global bundle for high-risk pregnancies. 76818 takes 26/TC split for imaging component. |
99395 + 99213 Mod 25 | Well-woman preventive + same-day problem E/M | Separate documentation and distinct ICD-10 per line. Preventive gets Z01.419. Problem gets the acute code. |
G0101 / Q0091 | Medicare pelvic-breast exam / Pap specimen collection | Medicare doesn't cover 99395. Carve out G0101 and Q0091 for Part B screening. Miss this and the visit goes unbilled. |
58300 + J-codes | IUD insertion + device supply | J7298 (Mirena), J7297 (Liletta), J7300 (Paragard), J7301 (Kyleena). Bill device and procedure separately. Wrong J-code = absorbed cost. |
57454 / 57522 | Colposcopy with biopsy / LEEP cone biopsy | Colposcopy bundles into LEEP when same encounter. NCCI edit pair. Pathology report confirms diagnostic code linkage. |
Maternity Denial Patterns
Four denial codes that cost OB-GYN practices the most
These four denial codes, verified against the NCCI Policy Manual, drive the bulk of OB-GYN claim denials we see.
Why does CO-4 hit OB-GYN hardest? Same-day preventive plus problem visits. It's the most common encounter pattern in gynecology, and payers auto-deny the Modifier 25 error on submission now. We onboarded a group that had dozens of well-woman visits a week denied because the note didn't separate the two visits with distinct histories per the X12 CARC code set. We built a documentation template in their first week and the CO-4 volume dropped to zero.
Division of Work
What your team handles versus what our team handles
We don't replace your clinical staff. We plug into your workflow and handle the billing side. Here's where the line sits.
Women's Health EHR Compatibility
Works with the systems your OB-GYN practice runs
We don't ask you to switch platforms. Your women's health EHR and prenatal flowsheet system stay in place, and we build the billing workflow around them. Custom integrations get scoped during your revenue assessment.

Common Questions
What OB-GYN practices ask before switching billing partners
Straight answers about maternity coding rules, onboarding, pricing, and the billing workflows that matter to your practice.
How do you bill when a patient switches insurance mid-pregnancy?
We unbundle the global package by visit count. Under the original payer, 1-3 visits bill as E/M (99212-99215), 4-6 as 59425, and 7+ as 59426. The new payer gets remaining antepartum visits, delivery (59409 or 59514), and postpartum (59430).
How do you handle Modifier 25 on same-day well-woman and problem visits?
We verify that documentation separates the preventive exam from the problem visit with distinct histories and distinct ICD-10 codes per line. Preventive gets Z01.419. Problem gets the acute diagnosis. Payers auto-deny without that separation in 2026.
How do you recover the full cost of LARC devices?
We verify device coverage under the patient's medical or pharmacy benefit before insertion, bill the correct procedure code (58300 for IUD, 11981 for Nexplanon), and pair it with the exact J-code. Wrong J-code or missing J-code means the practice absorbs a $700 to $1,400 loss.
How do you bill Medicare patients for well-woman exams?
Medicare doesn't cover the standard preventive visit (99395). We carve out G0101 for the pelvic and breast exam and Q0091 for Pap collection under Part B screening. Miss the carve-out and the encounter goes unbilled because 99395 rejects outright.
Can you bill fetal surveillance outside the global package?
Yes. Non-stress tests (59025) and biophysical profiles (76818) for high-risk pregnancies are billable per session outside the global bundle. 76818 takes a 26/TC split for imaging. Most practices leave this revenue on the table.
How long does onboarding take for an OB-GYN practice?
Five days. We load your payer contracts, import every active patient's EDD and global package status, configure your clearinghouse and EDI links, and verify that every LARC device J-code is mapped to your current inventory before we start processing.
