About 0BW170Z

0BW170Z is the ICD-10-PCS code for a revision procedure on the trachea using a via natural or artificial opening 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 other incision of larynx or trachea, the ICD-9-CM procedure title it maps to (31.3).

For a different body part, codes include 0BW070Z (tracheobronchial tree), 0BWK70Z (right lung), 0BWL70Z (left lung), 0BWQ70Z (pleura) and 0BWT70Z (diaphragm).

The same procedure with a different approach is coded 0BW100Z (open), 0BW130Z (percutaneous), 0BW140Z (percutaneous endoscopic), 0BW180Z (via natural or artificial opening endoscopic) and 0BW1X0Z (external).

With a different device, use 0BW172Z (monitoring device), 0BW177Z (autologous tissue substitute), 0BW17CZ (extraluminal device), 0BW17DZ (intraluminal device), 0BW17FZ (tracheostomy device), 0BW17JZ (synthetic substitute) and 1 more.

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”.
