ICD-10-PCS Code For Pulmonary Artery, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B32T includes procedures performed to create computerized tomographic multiplanar images of vascular structures in the pulmonary artery, left. These ICD-10-PCS codes are used for inpatient documentation when a computed tomography study of the left pulmonary artery is performed to assess anatomy, stenosis, embolism, or other vascular pathology. Accurate coding within the ICD-10-PCS B32T group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Pulmonary Artery, Left Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the left pulmonary artery, targeting the pulmonary arterial circulation within the thorax. Procedures involve computer-reformatted digital display of multiplanar images developed from multiple exposures of external ionizing radiation to evaluate arterial anatomy and pathology. These imaging procedures are assigned in the Imaging section and accurate coding supports appropriate inpatient documentation and reimbursement.

Code Attributes

Character	ICD-10-PCS Category	Code Group Details
B	Section	Imaging
3	Body System	Upper Arteries
2	Operation	Computerized Tomography (CT Scan)
T	Body Part	Pulmonary Artery, Left

When to Use

Use a code from this group when a CT scan with computer-reformatted multiplanar images is performed specifically to evaluate the left pulmonary artery. Typical clinical circumstances include investigation of suspected pulmonary embolism, arterial stenosis, aneurysm, or other localized vascular abnormalities of the left pulmonary artery.

ICD-10-PCS Code	Description
B32T0ZZ	Computerized Tomography (CT Scan) of Left Pulmonary Artery using High Osmolar Contrast
B32T1ZZ	Computerized Tomography (CT Scan) of Left Pulmonary Artery using Low Osmolar Contrast
B32TYZZ	Computerized Tomography (CT Scan) of Left Pulmonary Artery using Other Contrast
B32TZ2Z	Computerized Tomography (CT Scan) of Left Pulmonary Artery using Intravascular Optical Coherence
B32TZZZ	Computerized Tomography (CT Scan) of Left Pulmonary Artery

Typical Clinical Scenarios

A middle-aged patient arrives to the emergency department with sudden onset pleuritic chest pain, acute dyspnea, and hypoxemia after recent immobilization; clinicians suspect an acute pulmonary embolism affecting the left pulmonary arterial circulation, prompting inpatient CT angiographic evaluation with intravenous contrast to confirm embolus location and burden in the left pulmonary artery. Typical codes: B32T1ZZ, B32T0ZZ
An older patient with known left hilar mass and progressive exertional dyspnea is admitted for staging and preoperative planning; the team requires high-resolution multiplanar CT imaging of the left pulmonary artery to assess vessel encasement or invasion by the tumor and to guide surgical approach, often using low-osmolar contrast for improved image quality. Typical codes: B32T1ZZ, B32TYZZ
A patient in the inpatient vascular unit with prior pulmonary artery stent placement develops concern for in-stent restenosis or thrombosis limited to the left pulmonary artery; repeat CT with intravascular imaging adjuncts or specialized contrast techniques is performed to evaluate stent patency and plan potential intervention. Typical codes: B32TZ2Z, B32TYZZ
