ICD-10-PCS Code For Colon: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BD24 includes procedures performed to capture and reconstruct multiplanar computerized tomography images of the colon. These ICD-10-PCS codes are used for inpatient documentation when a CT scan of the colon is performed for diagnostic evaluation, treatment planning, or monitoring of gastrointestinal disease. Accurate coding within the ICD-10-PCS BD24 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Colon Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the colon performed using external ionizing radiation and computer-processed multiplanar image reconstruction. These procedures target the gastrointestinal system and provide detailed cross-sectional and multiplanar views of the colon for diagnostic evaluation. Accurate ICD-10-PCS coding of these CT procedures is important for inpatient reimbursement and for reflecting the complexity of imaging services provided.

When to Use

Use codes from this group when a CT scan of the colon is performed with computer reformatting or multiplanar reconstruction during an inpatient encounter. Do not use these codes for non-CT imaging modalities or for procedures that do not include computer-processed multiplanar image reconstruction.

ICD-10-PCS Code	Description
BD2400Z	Computerized Tomography (CT Scan) of Colon using High Osmolar Contrast, Unenhanced and Enhanced
BD240ZZ	Computerized Tomography (CT Scan) of Colon using High Osmolar Contrast
BD2410Z	Computerized Tomography (CT Scan) of Colon using Low Osmolar Contrast, Unenhanced and Enhanced
BD241ZZ	Computerized Tomography (CT Scan) of Colon using Low Osmolar Contrast
BD24Y0Z	Computerized Tomography (CT Scan) of Colon using Other Contrast, Unenhanced and Enhanced
BD24YZZ	Computerized Tomography (CT Scan) of Colon using Other Contrast
BD24ZZZ	Computerized Tomography (CT Scan) of Colon

Typical Clinical Scenarios

An elderly patient is admitted with acute abdominal pain, fever, and leukocytosis suspicious for perforated diverticulitis or abscess involving the colon. Inpatient evaluation requires cross-sectional assessment to identify colonic wall thickening, perforation, or intra-abdominal abscess and to guide urgent surgical or interventional drainage planning; a CT with multiplanar reconstruction of the colon is performed often with both unenhanced and contrast phases. Typical codes: BD2410Z, BD2400Z
A middle-aged patient is scheduled for inpatient monitoring after complicated colonoscopy with incomplete polyp evaluation due to poor bowel prep and ongoing bleeding; detailed imaging is needed to evaluate remaining colonic segments and localize bleeding or mural pathology. A contrast-enhanced CT scan with reformatted multiplanar images of the colon is used for diagnostic clarification and to plan further endoscopic or surgical management during the same admission. Typical codes: BD241ZZ, BD24Y0Z
A hospitalized patient with known colorectal cancer undergoes staging and treatment planning prior to anticipated resection, including assessment of local tumor extent and relationship to adjacent structures; multiplanar CT imaging of the colon provides high-resolution cross-sectional views for operative planning and margin assessment. Typical codes: BD24ZZZ, BD24YZZ
