About 0B9F00Z

0B9F00Z is the ICD-10-PCS code for a drainage procedure on the right lower lung lobe 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 incision of lung, the ICD-9-CM procedure title it maps to (33.1).

For a different body part, codes include 0B9100Z (trachea), 0B9200Z (carina), 0B9300Z (right main bronchus), 0B9400Z (right upper lobe bronchus), 0B9500Z (right middle lobe bronchus), 0B9600Z (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0B9F30Z (percutaneous), 0B9F40Z (percutaneous endoscopic), 0B9F70Z (via natural or artificial opening) and 0B9F80Z (via natural or artificial opening endoscopic).

With a different device, use 0B9F0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Major Chest Procedures” and “Other O.R. Procedures for Injuries”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
