ICD-10-PCS Code For Abdomen And Pelvis: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BW41 includes procedures performed to image anatomy or flow information in the abdomen and pelvis. These ICD-10-PCS codes are used for inpatient documentation when real time ultrasonography is performed to assess abdominal or pelvic organs, vasculature, or fluid collections. Accurate coding within the ICD-10-PCS BW41 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Abdomen And Pelvis Ultrasonography Procedure Overview

Procedures in this group involve real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves targeting the anatomical regions of the abdomen and pelvis. These imaging procedures use ultrasonography to visualize organs, vascular flow, and soft tissue structures within the abdominal and pelvic cavities. Accurate coding of these procedures supports appropriate inpatient documentation and impacts case mix and payment determinations.

When to Use

Use a code from this group when inpatient real time ultrasonography of the abdomen and pelvis is performed to evaluate clinical conditions such as pain, suspected organ pathology, vascular assessment, or fluid collections. Select the code that reflects the ultrasonography operation applied to the anatomical regions of the abdomen and pelvis in the International Classification of Diseases, Tenth Revision, Procedure Coding System.

ICD-10-PCS Code	Description
BW41ZZZ	Ultrasonography of Abdomen and Pelvis

Typical Clinical Scenarios

A middle-aged patient is admitted through the emergency department with acute, severe right upper quadrant abdominal pain, fever, and abnormal liver function tests suggesting possible acute cholecystitis or biliary obstruction. Inpatient clinicians order real-time ultrasonography of the abdomen and pelvis to evaluate the gallbladder, biliary tree, liver, and to look for pericholecystic fluid or other acute findings that influence immediate management. Typical codes: BW41ZZZ
An elderly hospitalized patient on the medical service has unexplained new-onset abdominal distention and tenderness; bedside imaging is needed to assess for ascites, intra-abdominal fluid collections, or organomegaly as part of the diagnostic workup. A diagnostic abdominal and pelvic ultrasonography providing real-time images is performed to guide subsequent interventions and further inpatient evaluation. Typical codes: BW41ZZZ
A postpartum patient develops severe pelvic pain and hemodynamic instability after a complicated delivery, raising concern for intra-abdominal bleeding or retained products; urgent bedside ultrasonography of the abdomen and pelvis is used to rapidly assess the uterus, pelvic structures, and presence of free fluid to guide emergent surgical or interventional decisions. Typical codes: BW41ZZZ
