| Name a root operation commonly performed on the lungs. | Excision (removal of part of lung tissue). |
| What is the purpose of the Anatomical Regions body systems in ICD-10-PCS? | To code procedures on body cavities, multiple layers/large surfaces, or unspecific body sites when no other system fits |
