About 0BWT4JZ
0BWT4JZ is the ICD-10-PCS code for a revision procedure on the diaphragm using a percutaneous endoscopic approach with synthetic substitute. 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 0BW04JZ (tracheobronchial tree) and 0BW14JZ (trachea).
The same procedure with a different approach is coded 0BWT0JZ (open), 0BWT3JZ (percutaneous), 0BWT7JZ (via natural or artificial opening), 0BWT8JZ (via natural or artificial opening endoscopic) and 0BWTXJZ (external).
With a different device, use 0BWT40Z (drainage device), 0BWT42Z (monitoring device), 0BWT47Z (autologous tissue substitute), 0BWT4KZ (nonautologous tissue substitute), 0BWT4MZ (diaphragmatic pacemaker lead) and 0BWT4YZ (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.
