The billing challenge
Where OB/GYN revenue leaks
OB/GYN billing is among the most complex in medicine. Global maternity packages, payer-specific modifier rules, strict postpartum filing windows, and 60–65% of denied claims are never resubmitted.
Global package billing errors
Billing separately for services bundled in CPT 59400 is the most common and costly denial trigger.
Prior auth gaps
Genetic testing, high-cost imaging, and surgical procedures require pre-approval. No auth means instant denial.
Underpayments accepted
Payers routinely underpay 5–12% on OB/GYN claims, knowing most practices don't audit their contracts.
Wrong or missing modifiers
Modifier 25, 51, 57, and 59 errors account for up to 40% of OB/GYN claim denials.
Timely filing failures
Postpartum and newborn codes have tight payer-specific windows. Missing them means permanent write-offs.
Denials not appealed
Most practices write off denials as losses. Zen appeals every denial and pursues old A/R recovery.

Frequently asked questions
What to expect
What makes OB/GYN billing different from other specialties?
OB/GYN uses episode-based billing spanning up to 9 months for a single global maternity package. One documentation gap early in pregnancy can cause a denial months later, by which time the filing window may have closed.
How much does OB/GYN billing outsourcing cost?
Zen charges 3–5% of collections, or a flexible resource model at $13–$15/hr, significantly less than the cost of one in-house biller when you include salary, benefits, training, and turnover.
How quickly can you recover denied OB/GYN claims?
We begin working existing denials immediately after onboarding. Most practices see measurable improvement within the first 30–60 days.
