About 0BWT77Z

0BWT77Z is the ICD-10-PCS code for a revision procedure on the diaphragm using a via natural or artificial opening approach with autologous tissue 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 0BW077Z (tracheobronchial tree) and 0BW177Z (trachea).

The same procedure with a different approach is coded 0BWT07Z (open), 0BWT37Z (percutaneous), 0BWT47Z (percutaneous endoscopic), 0BWT87Z (via natural or artificial opening endoscopic) and 0BWTX7Z (external).

With a different device, use 0BWT70Z (drainage device), 0BWT72Z (monitoring device), 0BWT7JZ (synthetic substitute), 0BWT7KZ (nonautologous tissue substitute), 0BWT7MZ (diaphragmatic pacemaker lead) and 0BWT7YZ (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.
