About 0BWL40Z

0BWL40Z is the ICD-10-PCS code for a revision procedure on the left lung using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0BW040Z (tracheobronchial tree), 0BW140Z (trachea), 0BWK40Z (right lung), 0BWQ40Z (pleura) and 0BWT40Z (diaphragm).

The same procedure with a different approach is coded 0BWL00Z (open), 0BWL30Z (percutaneous), 0BWL70Z (via natural or artificial opening), 0BWL80Z (via natural or artificial opening endoscopic) and 0BWLX0Z (external).

With a different device, use 0BWL42Z (monitoring device), 0BWL43Z (infusion device) and 0BWL4YZ (other 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.
