About 0B9T0ZX

0B9T0ZX is the ICD-10-PCS code for a drainage procedure on the diaphragm using an open 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 0B910ZX (trachea), 0B920ZX (carina), 0B930ZX (right main bronchus), 0B940ZX (right upper lobe bronchus), 0B950ZX (right middle lobe bronchus), 0B960ZX (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0B9T3ZX (percutaneous) and 0B9T4ZX (percutaneous endoscopic).

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 was added in FY2018, effective October 1, 2017.
