ICD-10-PCS Code For Lungs And Bronchi: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CB32 includes procedures performed to introduce radioactive materials for positron emission tomographic imaging in the lungs and bronchi. These ICD-10-PCS codes are used for inpatient documentation when three-dimensional functional imaging of pulmonary tissue and airway structures is performed using captured radioactive emissions. Accurate coding within the ICD-10-PCS CB32 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Lungs And Bronchi Positron Emission Tomographic Imaging Procedure Overview

This procedure group includes positron emission tomographic imaging of the lungs and bronchi, targeting the respiratory system to create three-dimensional functional images from captured radioactive emissions. These procedures involve introducing radioactive materials and using simultaneous detection 180 degrees apart to generate tomographic images. Accurate ICD-10-PCS coding ensures inpatient records reflect the specific imaging performed and supports correct case mix assignment and payment for nuclear medicine services.

When to Use

Use codes from this group when radioactive tracers are administered specifically for positron emission tomographic imaging of the lungs and bronchi during an inpatient stay. These codes apply when three-dimensional images are produced from simultaneous capture of emissions 180 degrees apart to evaluate pulmonary function or pathology.

ICD-10-PCS Code	Description
CB32KZZ	Positron Emission Tomographic (PET) Imaging of Lungs and Bronchi using Fluorine 18 (F-18)
CB32YZZ	Positron Emission Tomographic (PET) Imaging of Lungs and Bronchi using Other Radionuclide

Typical Clinical Scenarios

An adult patient is admitted from the emergency department with subacute onset of progressive dyspnea and unexplained hypoxemia after a nonproductive cough; chest radiograph and CT are inconclusive for focal consolidation, and clinical concern remains for multifocal pulmonary emboli or inflammatory/infiltrative disease. Inpatient PET imaging of the lungs and bronchi is ordered to evaluate regional pulmonary perfusion and metabolic activity to differentiate thromboembolic disease from infection or inflammation. Typical codes: CB32KZZ, CB32YZZ
A patient with a history of treated lung cancer is admitted for planned inpatient staging and assessment of suspected recurrent or metastatic disease after new respiratory symptoms and rising tumor markers; cross-sectional imaging suggests a pulmonary nodule not clearly characterized. Positron emission tomographic imaging of the lungs and bronchi is performed to obtain three-dimensional functional imaging and assess metabolic activity of the lesion to guide further management. Typical codes: CB32KZZ, CB32YZZ
A critically ill patient in the hospital with worsening respiratory failure and persistent unexplained ventilator weaning failure has nondiagnostic CT angiography due to contrast allergy; clinicians need functional imaging to assess diffuse pulmonary processes such as occult thromboembolism or inflammatory lung disease affecting airways. A PET study targeting the lungs and bronchi is performed using an appropriate radiotracer to generate tomographic images when other modalities are limited. Typical codes: CB32YZZ, CB32KZZ
