About 0B9T4ZZ
0B9T4ZZ is the ICD-10-PCS code for a drainage procedure on the diaphragm using a percutaneous endoscopic approach. 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 0B914ZZ (trachea), 0B924ZZ (carina), 0B934ZZ (right main bronchus), 0B944ZZ (right upper lobe bronchus), 0B954ZZ (right middle lobe bronchus), 0B964ZZ (right lower lobe bronchus) and 15 more.
The same procedure with a different approach is coded 0B9T0ZZ (open) and 0B9T3ZZ (percutaneous).
With a different device, use 0B9T40Z (drainage 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.
