Obstetrics And Gynecology Billing
Maximize your reimbursements with our specialized billing services for obstetrics and gynecology. We manage global maternity coding, the new 2026 CPT changes, and each insurer's specific policies for women's health.
Obstetrics and gynecology billing differs from general medical billing in fundamental ways. Unlike specialties focused on isolated consultations, obstetrics and gynecology care encompasses preventive services, chronic disease management, outpatient procedures, surgical interventions, and prolonged pregnancies, each governed by coding standards, insurer-specific policies, and unique reimbursement structures. The dual reimbursement model, which combines comprehensive obstetric packages with billing for gynecological procedures on a per-service basis, demands specialized expertise that generalist billing companies simply cannot provide.
At MedMaxbill, Inc., we offer comprehensive obstetrics and gynecology billing services specifically designed for women's health practices. Our team of certified billing specialists understands the unique coding, documentation, and reimbursement requirements for obstetrics and gynecology care, ensuring your practice receives maximum benefit and is fully compliant with regulations in 2026 and beyond.
The 2026 OB-GYN Billing Landscape: A Turning Point
2026 marks a transformative year for women’s health care reimbursement, with three simultaneous policy changes restructuring financial performance metrics for obstetrics and gynecology (OBG) practices.
New Obstetric CPT Codes
The long-awaited changes to the CPT coding structure for obstetric care were among the most discussed topics at the 2026 ACOG Annual Clinical and Scientific Meeting. The new CPT codes are designed to allow for more detailed documentation of care provided throughout pregnancy, enabling practices to more accurately represent the clinical effort and expertise required for each patient.
The previous global obstetric billing structure treated patients with uncomplicated pregnancies the same as those with extensive prenatal complications or complex postpartum needs, masking the true variation in clinical effort required. The revised framework more accurately reflects the cognitive and clinical complexity of prenatal and postpartum care.
Efficiency Adjustment in Medicare Physician Fee Schedule
The 2026 Medicare physician fee schedule introduced a 2.5% efficiency adjustment to Relative Value Units (RVUs) for non time based services. While the conversion factor saw a slight increase, the net effect for women's health procedures is negative, particularly for surgical services, which are already undervalued compared to men's specific procedures. For a clinic billing $3 million per month, a 2.5% reduction in RVUs for surgical procedures represents a decrease of more than $75,000 per month in profit margin.
HRSA's Expanded Preventive Services
Three significant changes took effect in January 2026, according to HRSA's new Women's Preventive Services Guidelines:
$0 Copay Follow up Charts:
When an initial screening mammogram requires a follow up MRI or ultrasound, insurance plans must now cover the secondary imaging with a $0 copay for the patient, increasing the volume of billable procedures.
HPV Self Collection Testing:
For women ages 30–65, primary high-risk HPV testing with at-home or in-clinic self-collection is now a fully covered and billable preventive service.
Cervical support services:
CMS now reimburses evidence-based patient support services, turning previously non-billable coordination work into a revenue-generating service.
Expansion of Medicaid postpartum coverage
Forty-six states have implemented permanent extensions of Medicaid postpartum coverage, creating new revenue opportunities but also requiring rigorous credential verification and updates to billing protocols.
Unique OB-GYN Billing Challenges
Obstetrics and gynecology practices face several recurring challenges that require specialized expertise for effective management.
1. Complexity of Maternity Billing
Maternity billing is the most defining characteristic and the most significant risk factor of revenue cycle management in obstetrics and gynecology. Because prenatal care, delivery, and postpartum services are bundled into a single obstetric package (CPT 59400 for vaginal delivery, 59510 for cesarean section), accurate reimbursement depends on maternity being considered a continuous episode of care.
However, discrepancies in overall billing often result in significant losses for practices. A practice with 45 deliveries per month can lose approximately $830,880 annually due to three common errors in bundled billing:
High-risk services billed as bundled services ($362,880 loss): High-risk pregnancies require separately billable services, in addition to the bundled package. Services for pre-existing conditions or pregnancy complications, such as weekly fetal well-being tests, insulin management for gestational diabetes, and diabetes education, are billed separately when supported by the appropriate diagnosis codes.
Postpartum services billed incorrectly ($70,560 loss): The postpartum period includes the day of delivery plus 42 days. Any visits after day 42 are billed separately, but many medical centers incorrectly bill these visits.
Diagnostic ultrasounds billed incorrectly (loss of $397,440): While Medicare includes most prenatal ultrasounds in its packages, private insurers such as UnitedHealthcare, Aetna, and Blue Cross allow separate billing of diagnostic ultrasounds when the medical need is documented and a complication diagnosis code supports the service.
2. Coding and Grouping of Gynecologic Surgical Procedures: Accuracy
CMS NCCI guidelines govern which gynecologic surgical procedures can be billed separately in multi-procedure visits. The grouping rules for laparoscopic hysterectomy with concurrent adnexal surgery, hysteroscopic procedures with cervical dilation, and endometrial ablation require the application of modifier 59 or XS to properly ungroup the separately billable components.
3. Confusion in Coding Preventive vs. Treatment Visits
Providers often address both preventive and treatment issues in a single visit, but the documentation may not clearly justify separate billing. Undercoding reduces revenue, while overcoding increases audit risk.
4. Delays and Failures in Prior Authorization
Imaging tests, procedures, and specialty medications increasingly require prior authorization. Authorization errors lead to avoidable denials, rescheduling of services, and patient dissatisfaction.
5. Challenges in Eligibility and Benefits Coordination
Eligibility management is particularly complex in obstetrics and gynecology billing, as pregnancy often coincides with changes in insurance coverage. Patients may change employers, plans, or Medicaid eligibility mid-pregnancy, and newborn enrollment adds further complexity.
