About 0B9T4ZX
0B9T4ZX is the ICD-10-PCS code for a drainage procedure on the diaphragm using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to biopsy of diaphragm, the ICD-9-CM procedure title it maps to (34.27).
For a different body part, codes include 0B914ZX (trachea), 0B924ZX (carina), 0B934ZX (right main bronchus), 0B944ZX (right upper lobe bronchus), 0B954ZX (right middle lobe bronchus), 0B964ZX (right lower lobe bronchus) and 15 more.
The same procedure with a different approach is coded 0B9T0ZX (open) and 0B9T3ZX (percutaneous).
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.
