About 0B9100Z
0B9100Z is the ICD-10-PCS code for a drainage procedure on the trachea using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other incision of larynx or trachea, the ICD-9-CM procedure title it maps to (31.3).
For a different body part, codes include 0B9200Z (carina), 0B9300Z (right main bronchus), 0B9400Z (right upper lobe bronchus), 0B9500Z (right middle lobe bronchus), 0B9600Z (right lower lobe bronchus), 0B9700Z (left main bronchus) and 15 more.
The same procedure with a different approach is coded 0B9130Z (percutaneous), 0B9140Z (percutaneous endoscopic), 0B9170Z (via natural or artificial opening) and 0B9180Z (via natural or artificial opening endoscopic).
With a different device, use 0B910ZZ (no device).
It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical category “Other Respiratory System O.R. Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
