AMA Clinical Examples in Radiology - 2021 Issue 4 (Fall)
High-Risk Obstetrical Ultrasound
DOCUMENTATION CHALLENGE Reports that fail to adequately support the coding for the procedure performed not only have serious implications for fraud and abuse but also may negatively affect how the physician can report the procedure. In each issue of Clinical Examples in Radiology , you will be provided with a documentation challenge. This documentation challenge will serve as a learning tool for both coders and physicians. High-Risk Obstetrical Ultrasound CLINICAL INDICATION Chronic hypertension, third trimester. Type 2 diabetes, third trimester. Polyhydramnios, third trimester, singleton. Scar from previous cesarean delivery (transverse incision). Pregnancy of 34 weeks gestation. PROCEDURE GESTATIONAL AGE :...

Article Overview
This premium article explains how to evaluate obstetrical ultrasound documentation against CPT obstetric ultrasound categories in a high-risk pregnancy case. It is aimed at coders, radiologists, and other clinicians who document or assign ultrasound services, and it discusses what information must be present in the report, how incomplete visualization affects code selection, and how related CPT guidance is used to compare limited, complete, detailed, and follow-up obstetric ultrasound studies.
Why This Topic Matters
Obstetrical ultrasound coding depends heavily on what is actually documented in the report. Missing elements, unclear nonvisualization, or incomplete exam details can change how the service is classified and can affect compliance and reporting accuracy.
