OB/GYN Billing Services
OB/GYN billing uniquely combines obstetric global package management with gynecological surgical coding, creating one of the most complex billing environments in medicine. The global obstetric package includes antepartum visits, delivery, and postpartum care under a single fee, but complications and non-routine services require separate billing. Our OB/GYN billing specialists navigate these complexities to ensure full reimbursement for every service.
Who This Page Is For
Common Billing Friction in OB/GYN
Global Obstetric Package Management
The global OB package (59400, 59510, 59610) bundles antepartum care, delivery, and postpartum care into one fee. Tracking which services fall inside versus outside the global package, especially for complications and additional visits, directly impacts reimbursement.
High-Risk Pregnancy Additional Billing
High-risk pregnancies generate services outside the global package including additional antepartum visits (modifier 24 or 25), non-stress tests, ultrasounds, and specialist consultations that must be billed separately with proper documentation.
Gynecological Surgery Coding Complexity
Laparoscopic and robotic gynecological procedures (hysterectomy, myomectomy, endometriosis excision) have multiple code options based on surgical approach, extent of procedure, and concurrent interventions that must be precisely matched.
OB/GYN-Specific Payer Issues We Watch For
Medicare
Issue: Does not cover routine obstetric care but does cover GYN services — OB patients with Medicare as secondary require careful coordination of benefits to avoid claim rejection
Our approach: We identify Medicare-eligible GYN services separately from OB care and coordinate primary/secondary billing to ensure all covered services are reimbursed
UnitedHealthcare
Issue: Requires antepartum visit counts to match the billed global package code, and denies claims when the provider switches from global to per-visit billing mid-pregnancy without notification
Our approach: We track antepartum visits from the first prenatal encounter and submit global package codes with supporting visit documentation that matches the billed package
Aetna
Issue: Bundles the first ultrasound into the global OB package on many plans, denying separate payment for the initial dating ultrasound
Our approach: We verify Aetna plan-specific global package inclusions before billing and document medical necessity for ultrasounds that fall outside the bundled package
Medicaid
Issue: State programs vary significantly in global OB package definitions, with some states separating delivery from antepartum care and others bundling everything into one payment
Our approach: We maintain state-specific Medicaid OB billing matrices and bill according to each state's global vs unbundled payment structure

Real Results
The Challenge
A 6-provider OB/GYN practice was losing revenue on unplanned cesarean section coding, missing separately billable antepartum complications, and had inconsistent global OB package billing across providers
Our Approach
We standardized global OB package billing with antepartum visit tracking, implemented complication code capture for conditions outside the global period, and corrected unplanned C-section coding with proper modifiers
Key Outcomes
- check_circle Antepartum complication billing added $6,200 per month
- check_circle Unplanned C-section coding accuracy reached 100%
- check_circle Global OB package billing consistency improved from 72% to 99%
- check_circle Annual revenue increased by $156K
“Our providers were treating antepartum complications and not billing for them because they assumed everything was included in the global OB package. MedPrecision showed us what is separately billable.”
Why General Billing Teams Miss OB/GYN Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for ob/gyn coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in ob/gyn.
Under-coding high-complexity visits
OB/GYN encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for ob/gyn procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn ob/gyn denials quickly.
“The global OB package is both the largest single payment and the biggest source of lost revenue in OB/GYN billing. Practices routinely absorb antepartum complications, unplanned procedures, and high-risk monitoring that should be billed separately.”

OB/GYN Billing Terms
- Global OB Package
- A bundled payment covering routine antepartum visits, delivery, and postpartum care. Includes a set number of prenatal visits, labor and delivery management, and one postpartum visit. Services beyond the included scope are separately billable.
- Antepartum Complication
- A condition arising during pregnancy that falls outside routine prenatal care and is separately billable from the global OB package. Examples include gestational diabetes management, preeclampsia monitoring, and preterm labor evaluation.
- Global Period (OB)
- The timeframe covered by the global OB package, typically from the first antepartum visit through delivery and 6 weeks postpartum. E/M visits during this period for conditions unrelated to pregnancy are separately billable.
- Unplanned Cesarean Section
- A C-section performed after labor has begun when vaginal delivery was the planned method. Coded differently from a planned C-section and may require modifier documentation if converting from a trial of labor.
- Fetal Non-Stress Test (NST)
- A monitoring procedure assessing fetal heart rate response to movement. Billed with 59025 and separately billable from the global OB package when medically indicated for high-risk pregnancies.
- Modifier 22 (Increased Procedural Services)
- Applied to surgical procedures when the work required substantially exceeds the typical procedure. Common in OB/GYN for complicated deliveries, extensive adhesion lysis, or procedures on patients with high BMI.

Request Review arrow_forwardWhat is included in the global obstetric billing package?
The global OB package includes all routine antepartum visits (typically 13 visits), the delivery itself (vaginal or cesarean), and postpartum care through 6 weeks. We track each component and bill separately for any services that fall outside the package, such as complications, additional visits beyond routine, and high-risk monitoring.
How do you handle billing when a patient transfers care during pregnancy?
When a patient transfers in or out during pregnancy, we use the antepartum-only codes (59425, 59426) based on the number of visits provided, plus separate delivery and postpartum codes if applicable. We coordinate with the other provider's biller to ensure no duplicate billing occurs.
Can you bill for an E/M visit on the same day as a gynecological procedure?
Yes, when the E/M visit involves a separately identifiable decision to perform the procedure or addresses an unrelated problem. We apply modifier 25 to the E/M code and ensure documentation supports the separate nature of both services.
