ICD-10-PCS Code For Tracheobronchial Tree, Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BB27 includes procedures performed to image the tracheobronchial tree, right using computerized tomography. These ICD-10-PCS codes are used for inpatient documentation when multiplanar, computer reformatted digital displays of the right tracheobronchial tree are produced from multiple exposures of external ionizing radiation. Accurate coding within the ICD-10-PCS BB27 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Tracheobronchial Tree, Right Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the right tracheobronchial tree within the respiratory system. These procedures involve computer reformatted multiplanar digital displays developed from multiple external ionizing radiation exposures to visualize airway anatomy. Accurate ICD-10-PCS coding matters for inpatient reimbursement because it documents the imaging modality and targeted anatomy, which affects case mix and payment.

When to Use

Use a code from this group when inpatient care includes computerized tomography with computer reformatted multiplanar digital displays specifically targeting the right tracheobronchial tree. These codes apply when multiple external ionizing radiation exposures are captured and reconstructed to evaluate or document airway structure on the right side.

Typical Clinical Scenarios

An elderly patient is admitted from the emergency department with acute onset stridor and respiratory distress after inhalation injury. The inpatient team orders a multiplanar CT of the right tracheobronchial tree with both unenhanced and contrast-enhanced phases using low osmolar iodinated contrast to assess luminal compromise, edema, and possible inhalational burns to the right-sided airways prior to airway management decisions. Imaging is performed to delineate the extent of airway injury and guide urgent treatment. Typical codes: BB2710Z
A middle-aged patient with a history of recurrent localized right-sided bronchiectasis is admitted for elective inpatient workup before planned surgical resection. A diagnostic CT study with multiplanar reformats of the right tracheobronchial tree is obtained using low osmolar contrast only (enhanced imaging) to map airway anatomy and bronchial artery relationships for operative planning. Typical codes: BB271ZZ
A patient previously treated for right mainstem bronchial stenosis returns with progressive dyspnea and suspected restenosis after prior intervention. Inpatient imaging is performed to compare current airway caliber with prior studies, using both unenhanced and enhanced phases with high osmolar contrast to evaluate recurrent narrowing, scar tissue, or extrinsic compression of the right tracheobronchial tree. Typical codes: BB2700Z
