Step-by-step explanation:
The correct root operation term used in ICD-10-PCS (International Classification of Diseases, Tenth Revision, Procedure Coding System) for a biopsy of the left lower lobe of the lung is excision. In the context of ICD-10-PCS, an excision is defined as cutting out or off, without replacement, a portion of a body part.
A biopsy involves the surgical removal of a tissue specimen for analysis in a medical laboratory. This procedure is often performed to diagnose conditions such as cancer and is classified as an excision since it entails removing a portion of a body part for diagnostic examination.
Selecting the appropriate root operation term, such as "Excision," is crucial for accurate coding in ICD-10-PCS, ensuring precise representation of medical procedures in healthcare documentation and facilitating effective communication among healthcare professionals.
