About 0BRT4KZ

0BRT4KZ is the ICD-10-PCS code for a replacement procedure on the diaphragm using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to laparoscopic repair of diaphragmatic hernia, abdominal approach, the ICD-9-CM procedure title it maps to (53.71).

For a different body part, codes include 0BR14KZ (trachea), 0BR24KZ (carina), 0BR34KZ (right main bronchus), 0BR44KZ (right upper lobe bronchus), 0BR54KZ (right middle lobe bronchus), 0BR64KZ (right lower lobe bronchus) and 4 more.

The same procedure with a different approach is coded 0BRT0KZ (open).

With a different device, use 0BRT47Z (autologous tissue substitute) and 0BRT4JZ (synthetic substitute).

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 326 (Stomach, Esophageal and Duodenal Procedures with MCC), DRG 327 (Stomach, Esophageal and Duodenal Procedures with CC) and DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Stomach, Esophageal and Duodenal Procedures”, “Other O.R.
