OB/GYN practices face some of the most complex billing challenges in healthcare. From global maternity packages and ultrasound billing to preventive care, modifiers, and payer-specific rules, even small errors can snowball into massive revenue loss.

Industry data shows that OB/GYN practices lose up to 30% of potential revenue each year due to billing inefficiencies, denials, under coding, and compliance gaps.

The good news?
These losses are avoidable—with the right specialized OB/GYN billing services.

The Real Reasons OB/GYN Practices Lose Revenue

1️⃣ Global Maternity Billing Errors

Global OB packages are one of the largest revenue leak sources.

Common mistakes include:

Incorrect use of global vs split billing
Missing antepartum or postpartum visits
Misbilling high-risk pregnancy services
Incorrect CPT usage (59400, 59510, 59610, 59618)

📉 Result: Underpayments, recoupments, and denied claims

2️⃣ Modifier -25 & Same-Day Visit Denials

OB/GYN practices frequently bill:

Annual well-woman exams
Problem-oriented visits
Ultrasounds on the same day

Improper modifier usage (especially -25) triggers:

Automatic denials
Post-payment audits
Refund demands

3️⃣ Ultrasound & Diagnostic Coding Mistakes

Ultrasound billing is a high-risk audit area.

Revenue is lost when:

Medical necessity is poorly documented
Transvaginal vs abdominal ultrasounds are miscoded
Professional vs technical components are confused
Bundling rules are ignored

💰 Many practices lose thousands per month here alone.

4️⃣ Preventive vs Problem Visit Misclassification

Billing preventive care incorrectly can:

Shift cost to the practice
Trigger payer rejections
Cause patient billing disputes

Payers closely scrutinize:

ICD-10 diagnosis linking
Documentation supporting separate services
Correct CPT pairing

5️⃣ Prior Authorization & Eligibility Gaps

Missed or delayed authorizations for:

High-risk pregnancy imaging
Genetic testing
Advanced ultrasounds

lead to:

Claim denials
Delayed care
Cash flow disruptions

6️⃣ In-House Billing Limitations

In-house billing teams often struggle with:

Constant OB/GYN coding changes
Staff turnover & burnout
Backlogs in A/R follow-up
Limited payer-specific expertise

This results in:

Higher A/R days
Missed appeals
Underreported revenue
