About 0BWL0YZ

0BWL0YZ is the ICD-10-PCS code for a revision procedure on the left lung using an open approach with other 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 0BW00YZ (tracheobronchial tree), 0BWK0YZ (right lung), 0BWQ0YZ (pleura) and 0BWT0YZ (diaphragm).

The same procedure with a different approach is coded 0BWL3YZ (percutaneous), 0BWL4YZ (percutaneous endoscopic), 0BWL7YZ (via natural or artificial opening) and 0BWL8YZ (via natural or artificial opening endoscopic).

With a different device, use 0BWL00Z (drainage device), 0BWL02Z (monitoring device) and 0BWL03Z (infusion 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 was added in FY2018, effective October 1, 2017.
