About 0B9F0ZX

0B9F0ZX is the ICD-10-PCS code for a drainage procedure on the right lower lung lobe 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 open biopsy of lung, the ICD-9-CM procedure title it maps to (33.28).

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 0B9F3ZX (percutaneous), 0B9F4ZX (percutaneous endoscopic), 0B9F7ZX (via natural or artificial opening) and 0B9F8ZX (via natural or artificial opening 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), DRG 165 (Major Chest Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R.
