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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BW25 includes procedures performed to capture and computer reformat multiplanar images of the chest, abdomen, and pelvis. These ICD-10-PCS codes are used for inpatient documentation when computerized tomography imaging of these anatomical regions is performed for diagnostic evaluation or treatment planning. Accurate coding within the ICD-10-PCS BW25 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Chest Abdomen And Pelvis Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging studies of the chest, abdomen, and pelvis that use external ionizing radiation to capture multiple exposures and create multiplanar reformatted images. These procedures target the anatomical regions of the chest, abdomen, and pelvis and produce detailed cross-sectional and reformatted views for diagnostic evaluation. Accurate ICD-10-PCS coding of these computerized tomography procedures is important for inpatient reimbursement because it documents the specific imaging service performed and supports appropriate case mix assignment.

When to Use

Use a code from this group when a patient undergoes computerized tomography of the chest, abdomen, and pelvis with computer reformatting of multiplanar images during an inpatient encounter. Select the code when the clinical documentation confirms the imaging modality as computerized tomography and specifies the anatomical regions imaged.

Typical Clinical Scenarios

An adult presents to the emergency department with sudden onset severe abdominal pain, hemodynamic stability, and concern for intra-abdominal hemorrhage after a motor vehicle collision. The inpatient team orders a contrast-enhanced CT of the chest, abdomen, and pelvis to evaluate for solid organ injury, active bleeding, and thoracoabdominal trauma; both unenhanced and contrast-enhanced phases are obtained to differentiate hemorrhage from contrast extravasation. The imaging is performed using intravenous low-osmolar iodinated contrast during the same inpatient encounter. Typical codes: BW2510Z
A 62-year-old patient with newly diagnosed colorectal cancer is admitted for staging and preoperative planning. The inpatient workup includes a multiphase CT of the chest, abdomen, and pelvis with intravenous contrast to assess for hepatic and pulmonary metastases and to guide surgical planning; both unenhanced and enhanced series are acquired to characterize liver lesions. The study uses a high-quality contrast agent appropriate for detailed diagnostic delineation. Typical codes: BW2500Z
A hospitalized patient with chronic kidney disease develops worsening abdominal pain and suspected septic complications after recent abdominal surgery; initial noncontrast CT was nondiagnostic. Because renal function limits contrast options, the team orders a diagnostic CT of the chest, abdomen, and pelvis using an alternative contrast agent deemed lower nephrotoxic risk and acquires both unenhanced and enhanced images to evaluate for abscess, anastomotic leak, or fluid collections. Typical codes: BW25Y0Z
