About 0BW042Z

0BW042Z is the ICD-10-PCS code for a revision procedure on the tracheobronchial tree using a percutaneous endoscopic approach with monitoring 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 bronchus, the ICD-9-CM procedure title it maps to (33.0).

For a different body part, codes include 0BW142Z (trachea), 0BWK42Z (right lung), 0BWL42Z (left lung), 0BWQ42Z (pleura) and 0BWT42Z (diaphragm).

The same procedure with a different approach is coded 0BW002Z (open), 0BW032Z (percutaneous), 0BW072Z (via natural or artificial opening), 0BW082Z (via natural or artificial opening endoscopic) and 0BW0X2Z (external).

With a different device, use 0BW040Z (drainage device), 0BW043Z (infusion device), 0BW047Z (autologous tissue substitute), 0BW04CZ (extraluminal device), 0BW04DZ (intraluminal device), 0BW04JZ (synthetic substitute) and 2 more.

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) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical category “Major Chest Procedures”.

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