About the BB1 Code Range
The ICD-10-PCS root operation Fluoroscopy (BB1) in the Imaging section refers to the use of continuous X-ray imaging to visualize internal structures in real time, primarily for diagnostic purposes. This operation captures dynamic images of body parts, aiding in the evaluation of their function and condition.
In this classification, Fluoroscopy is applied to the Respiratory System and related structures. Specific codes include imaging of the Right Lung (BB12ZZZ), Left Lung (BB13ZZZ), and Bilateral Lungs (BB14ZZZ). Additionally, fluoroscopic evaluation may involve the Diaphragm (BB16ZZZ), Mediastinum (BB1CZZZ), and Upper Airways (BB1DZZZ). Some codes specify the use of contrast media for enhanced imaging of the Right (BB17YZZ), Left (BB18YZZ), or Bilateral Tracheobronchial Trees (BB19YZZ). These precise codes facilitate accurate documentation of fluoroscopic procedures within respiratory imaging.
