ICD-10-PCS Code For Fetal Umbilical Cord: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BY47 includes procedures performed to image fetal umbilical cord structures and blood flow in the fetus and obstetrical body system. These ICD-10-PCS codes are used for inpatient documentation when ultrasonographic real-time display of the fetal umbilical cord is performed to assess anatomy or flow. Accurate coding within the ICD-10-PCS BY47 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Fetal Umbilical Cord Ultrasonography Procedure Overview

Procedures in this group involve real-time display ultrasonography focused on the fetal umbilical cord within the fetus and obstetrical body system. These procedures capture reflected and attenuated high-frequency sound waves to produce images or flow information of the cord and its vessels. Accurate coding ensures inpatient records reflect the specific imaging performed and supports correct case mix and reimbursement.

When to Use

Use codes from this group when an inpatient ultrasonography examination is performed specifically to visualize the fetal umbilical cord or evaluate umbilical vessel flow. These codes apply when the imaging is intended to diagnose, monitor, or document cord anatomy or hemodynamics during obstetrical care.

BY47ZZZ	Ultrasonography of Fetal Umbilical Cord

Typical Clinical Scenarios

A pregnant patient at 34 weeks presents to labor and delivery with decreased fetal movements and nonreassuring fetal heart rate tracing. Inpatient evaluation includes real-time ultrasonography focused on the fetal umbilical cord to assess cord vessel patency and umbilical blood flow to help determine fetal status and guide urgent management. Findings may influence need for expedited delivery. Typical codes: BY47ZZZ
A patient admitted for planned induction at 39 weeks with a history of intrauterine growth restriction undergoes scheduled inpatient ultrasound to monitor fetal well-being. The examination specifically images the fetal umbilical cord and assesses blood flow in the cord vessels to evaluate placental-fetal circulation and inform timing of delivery. Typical codes: BY47ZZZ
A patient with a prior ultrasound showing a single umbilical artery is admitted for fetal surveillance after new-onset oligohydramnios. Inpatient ultrasonography is performed to re-evaluate the umbilical cord anatomy and Doppler flow in the remaining cord vessel to assess for worsening compromise and to guide antenatal management decisions. Typical codes: BY47ZZZ
