How to appeal an OB Ultrasound Frequency denial

Why it gets denied

• The number of ultrasounds billed exceeds the payer's per-pregnancy allowance for a routine pregnancy
• A follow-up/growth scan (76816) wasn't tied to a high-risk indication
• The detailed anatomic exam (76811) was billed without the maternal/fetal risk factor
• Transvaginal (76817) was denied as bundled with the same-day transabdominal study

What overturns it

• Document the high-risk indication (growth restriction, diabetes, hypertension, prior loss) that justifies scans beyond the routine allowance
• Tie each follow-up scan to the monitored condition
• Support the detailed anatomy code with the risk factor and the full documented survey
• Show the transvaginal study was separately identifiable

How do I appeal an OB Ultrasound Frequency denial?

OB ultrasound denials are almost all frequency: payers cover a limited number of scans per pregnancy and deny the fourth-plus study, the repeat detailed anatomy scan, or the follow-up growth scan as exceeding the routine allowance without a documented indication. To overturn it: document the high-risk indication (growth restriction, diabetes, hypertension, prior loss) that justifies scans beyond the routine allowance; tie each follow-up scan to the monitored condition; support the detailed anatomy code with the risk factor and the full documented survey; show the transvaginal study was separately identifiable.

Is a OB Ultrasound Frequency denial worth appealing?

OB ultrasound is high-volume, and frequency denials pile up across a panel of pregnancies. They're recoverable whenever the chart documents the risk factor that moves the pregnancy out of the routine-scan allowance. You pay 25% only on what's recovered, so there's no cost to working the winnable ones.
