In ICD-9-CM-3,the coding point of simple bronchoscopy is to distinguish the type of bronchoscopy,which is usually divided into fiberoptic bronchoscopy,tracheostomy bronchoscopy,and other bronchoscopy examinations;In addition to paying attention to the type of bronchoscopy,the coding of bronchoscopy biopsy also needs to clarify the biopsy site,which is mostly in the lungs or bronchi;There are two query paths in ICD-9-CM-3 for the encoding of bronchoscopic stent placement and bronchoballoon dilation surgery.In the category list,it is generally important to pay attention to whether the surgical method in the category is endoscopic,and to verify whether the encoding content in the category list is consistent with the operation content;The coding of valve placement under bronchoscopy is related to the number of implanted valves,generally divided into single lobe and multi lobe;When removing substances from the bronchus under bronchoscopy,attention should be paid to distinguishing the type of substance being removed.The foreign body removal code is 98.15,and the therapeutic device removal code is 33.78;Bronchoscopic lesion removal surgery is often divided into resection surgery and destruction surgery,and when coding,attention should be paid to the type of removal surgery and the location of the lesion.In coding practice,the coding used for bronchoscopic balloon dilation surgery in the National Clinical Edition 3.0 of the Classification Code for Surgical Operations is different from the ICD-9-CM-3 query coding.The former emphasizes that dilation surgery is an endoscopic operation;Although the coding categories for destructive surgery and resection surgery in the National Clinical Version 3.0 of the Classification Code for Surgical Operations are the same,there are differences in the extension codes for bronchoscopic lesion removal.In coding practice,appropriate extension codes should be selected based on the type of removal surgery to ensure the accuracy and rationality of bronchoscopic operation coding.
