What Key Challenges Make OB/GYN Medical Billing Services Essential?
Global Maternity Package Complexity:
OB/GYN billing must correctly apply global maternity packages, which bundle prenatal, delivery, and postpartum care using a single CPT code. Misapplication can cause claim denials and revenue loss.
CPT Code Updates for Tumor Excision:
CPT codes 49203 – 49205 are replaced by codes 49186 – 49190 that require providers to report the total size of all tumors or cysts removed. This change demands more precise documentation and coding expertise.
Insurance Verification and Prior Authorization:
The differences in insurance between Medicaid and private payers make OB/GYN billing complex. Other than that, procedures like hysterectomies and LEEPs require prior authorizations supported by proper clinical documentation.

Frequently Asked Questions (FAQs)
Get answers to the most common questions that Obstetrics and Gynecology (OB/GYN) practices ask about our billing services.
OB/GYN billing covers bundled maternity packages, surgical procedures, and preventive women’s health services. Billing for prenatal, delivery, and postpartum care falls under global maternity codes (59400 to 59622), which have strict payer rules. Errors, such as including unrelated office visits in the global package or incorrect use of modifiers (-24 for unrelated visits or -25 for same-day services), are common causes of denials. Specialized knowledge is essential to code these correctly and protect revenue.
We have certified coders who specialize in OB/GYN and complete regular training on CPT, ICD-10, and payer updates.
