About 0B9T40Z
0B9T40Z is the ICD-10-PCS code for a drainage procedure on the diaphragm using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
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 0B9140Z (trachea), 0B9240Z (carina), 0B9340Z (right main bronchus), 0B9440Z (right upper lobe bronchus), 0B9540Z (right middle lobe bronchus), 0B9640Z (right lower lobe bronchus) and 15 more.
The same procedure with a different approach is coded 0B9T00Z (open) and 0B9T30Z (percutaneous).
With a different device, use 0B9T4ZZ (no device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
