Most OB/GYN practices lose 15–30% of collectable revenue to billing errors, denied claims, and missed codes. Our free calculator shows you exactly how much your practice is leaving on the table.
Revenue leakage in OB/GYN billing isn't always visible. Unlike a denied claim — which at least shows up in your AR as an obvious problem — revenue leakage often happens silently: codes never billed, modifiers never applied, global periods never tracked, antepartum components counted wrong.
The average OB/GYN practice loses 15–30% of its collectable revenue to billing inefficiencies. For a practice generating $1.5M in annual collections, that's $225,000–$450,000 walking out the door every year.
The Most Common Sources of OB/GYN Revenue Leakage
Denied Claims — 19% of In-Network Claims
In 2025, 19% of in-network claims were denied by commercial payers. In OB/GYN, denial rates are often higher because of the complexity of global maternity billing, modifier requirements for surgical procedures, and telehealth coding rules.
The cost to rework a single denied claim is $57.23 in staff time and administrative overhead. If your practice submits 500 claims per month and 19% are denied, you're spending $5,400 per month just chasing denials — before counting the revenue you never recover.
Underbilling — The Silent Killer
Underbilling is less visible than denials but often costs more. Common underbilling scenarios in OB/GYN:
- ›Billing 99213 when the visit complexity supports 99214
- ›Missing modifier 22 on complicated surgical procedures
- ›Not billing CPT 59430 for standalone postpartum visits
- ›Omitting J-codes for IUD device supply alongside 58300
- ›Never billing 99401–99404 for standalone preventive counseling
A single coding audit typically identifies $50,000–$200,000 in underbilled services for a mid-size OB/GYN practice.
In-House Billing Overhead
In-house billing staff carrying average salaries of $45,000–$65,000 plus benefits represent $56,250–$81,250 per year in fully loaded cost per biller. For practices with 2–3 billers, that's $112,500–$243,750 per year in overhead.
Outsourced billing typically costs 4–7% of collections — for a practice collecting $1.5M annually, that's $60,000–$105,000 per year, often less than the cost of equivalent in-house staff while achieving higher collection rates.
Timely Filing Failures
Every payer has a timely filing deadline — Medicare is 12 months from date of service, but many commercial payers are 90 or 180 days. Claims submitted after the timely filing window are non-recoverable. Practices with manual billing workflows frequently miss timely filing deadlines on denied claims that were never worked.
