About 0BWT32Z

0BWT32Z is the ICD-10-PCS code for a revision procedure on the diaphragm using a percutaneous 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 other operations on diaphragm, the ICD-9-CM procedure title it maps to (34.89).

For a different body part, codes include 0BW032Z (tracheobronchial tree), 0BW132Z (trachea), 0BWK32Z (right lung), 0BWL32Z (left lung) and 0BWQ32Z (pleura).

The same procedure with a different approach is coded 0BWT02Z (open), 0BWT42Z (percutaneous endoscopic), 0BWT72Z (via natural or artificial opening), 0BWT82Z (via natural or artificial opening endoscopic) and 0BWTX2Z (external).

With a different device, use 0BWT30Z (drainage device), 0BWT37Z (autologous tissue substitute), 0BWT3JZ (synthetic substitute), 0BWT3KZ (nonautologous tissue substitute), 0BWT3MZ (diaphragmatic pacemaker lead) and 0BWT3YZ (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) 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.
