Billing built for OB-GYN practices, not generic medical.
Global maternity billing is a puzzle most billers get wrong. Preventive versus diagnostic visits, ultrasound frequency rules, and delivery bundling all trip up general medical billers. Our OB-GYN coders handle it every day. Same 4.99% flat rate. Same dedicated manager who knows the difference between 59400 and 59409.
OB-GYN CPT codes we handle every day.
Global maternity bundling, ultrasound frequency limits, and preventive-versus-diagnostic modifier rules. Our OB-GYN coders know the details.
Global Vaginal Delivery
Antepartum, delivery, postpartum bundled. Watch for care that spans multiple providers or gets interrupted.
Global Cesarean Delivery
Cesarean version of global obstetric care. Higher reimbursement, same bundling considerations.
Obstetric Ultrasound
Complete transabdominal ultrasound, first trimester or later. Frequency limits vary by payer.
Total Abdominal Hysterectomy
90-day global period. Modifier 22 for extended procedures. Concurrent procedures need modifier 51.
Colposcopy with Biopsy
Biopsy and endocervical curettage. Watch for J-codes on any material sent to pathology.
Preventive Visit, 18-39
Well-woman annual. Cannot be billed same day as problem-focused visit without modifier 25.
Where OB-GYN billing usually breaks.
Three patterns account for most denials in OB-GYN. Our specialized coders catch these before submission.
Global Period Rules
Global maternity claims denied when antepartum visits were billed separately, or when care spans providers without proper handoff coding.
Preventive vs Diagnostic
Well-woman visits denied when a problem is addressed in the same encounter without modifier 25 or clear documentation split.
Ultrasound Prior Auth
OB ultrasounds beyond the initial denied for missing prior auth or exceeding payer frequency limits.
How a pregnancy becomes clean revenue at every stage.
Global maternity is not one bill at the end. It’s a five-stage workflow that starts at the first prenatal visit and ends after the postpartum visit. Miss a step and revenue leaks.
Confirmation Visit
First OB visit billed separately (99201-99215). Global package starts only after confirmation.
Antepartum Care
Routine prenatal visits logged into global package. Any high-risk visits coded separately with proper modifiers.
Ultrasounds & Labs
Ultrasounds billed separately outside global (76805, 76811). Frequency tracked per patient per payer.
Delivery
Vaginal (59400) or cesarean (59510) global code billed. If C-section after labor, modifier 22 for extended care.
Postpartum Complete
Global package closed at 6-week postpartum visit. Any complications billed separately with proper diagnosis codes.
Patient transfers happen. When care moves mid-pregnancy or a delivery goes to another provider, we unbundle correctly using 59425, 59426, or the delivery-only codes. No revenue lost, no double billing.
OB-GYN-specific rules we track for you.
Global maternity rules, Medicaid state variations, and preventive coverage under the ACA all evolve. We track updates so your practice stays clean.
Payer-specific antepartum visit thresholds tracked
Most payers require 13+ visits for full global (59400). Fewer visits mean itemized billing (59425 or 59426). Rules vary by payer and state Medicaid. We maintain a payer rulebook so every claim is right.
OB ultrasound coverage rules by payer maintained
Commercial payers typically cover 3 routine OB ultrasounds. Additional scans need medical necessity documentation and often prior auth. We track allowed frequency per patient per payer.
Well-woman and preventive screenings billed correctly
ACA requires zero-cost preventive care for well-woman visits, contraception, and specific screenings. Miscoded and it bills as diagnostic, patient gets a bill, complaints follow. We keep the split clean.
State-specific Medicaid maternity rules tracked
Medicaid maternity rules vary dramatically by state. Some states carve out specific services, some require CPS reporting for certain diagnoses. We keep state-specific rulebooks current across all 20+ states we serve.
Full-service OB-GYN billing.
Everything an OB-GYN practice needs, from global maternity packages to gynecological surgeries and well-woman preventive care.
Global Maternity Billing
Antepartum, delivery, postpartum bundled correctly. Unbundled when clinically appropriate.
Obstetric Ultrasound
Frequency tracked per patient. Prior auth verified before every scan past the first.
Gynecological Surgery
Hysterectomy, myomectomy, cystoscopy. Modifier 22 and 51 applied correctly.
Well-Woman Preventive
ACA-covered preventive services billed correctly with no unexpected patient charges.
Fertility & MFM
Maternal-fetal medicine consults, high-risk OB, and infertility diagnostics coded correctly.
Dedicated Manager
Same person answers when you have global maternity questions or need an appeal filed.
“We’re a five-provider OB-GYN group and our previous biller kept unbundling global maternity when they shouldn’t have. On the flip side, they missed billing our ultrasounds separately when they should have. CureMed fixed both in the first month. Fifty-four thousand a month back on the books.”
Common questions about OB-GYN billing.
What is OB-GYN billing?
OB-GYN billing covers claims for obstetric and gynecological services including global maternity care, deliveries, gynecological surgeries, well-woman visits, and obstetric ultrasound. It requires deep knowledge of global maternity packages, preventive versus diagnostic coding, and payer-specific ultrasound rules.
What are the most common OB-GYN CPT codes?
Common OB-GYN CPT codes include 59400 (global obstetric care with vaginal delivery), 59510 (cesarean delivery), 76805 (obstetric ultrasound), 58150 (total hysterectomy), 57454 (colposcopy), and 99385/99395 (preventive visits).
Why do OB-GYN claims get denied?
Top reasons include global period rule violations (31%), preventive versus diagnostic coding errors (24%), and prior authorization issues for ultrasounds (17%). Global maternity unbundling is a particularly common issue that leaves revenue on the table.
Do you handle Medicaid maternity billing?
Yes. Medicaid maternity rules vary dramatically by state. We maintain state-specific rulebooks across all 20+ states we serve, so your Medicaid claims align with each state’s specific requirements.
How do you handle patient transfers mid-pregnancy?
When care transfers to or from your practice mid-pregnancy, we unbundle correctly using 59425 (antepartum care only, 4-6 visits), 59426 (7+ visits), or delivery-only codes. Your practice bills only for what you provided, no revenue lost, no double billing.
