About 0B9M0ZZ

0B9M0ZZ is the ICD-10-PCS code for a drainage procedure on the bilateral lungs using an open 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 incision of lung, the ICD-9-CM procedure title it maps to (33.1).

For a different body part, codes include 0B910ZZ (trachea), 0B920ZZ (carina), 0B930ZZ (right main bronchus), 0B940ZZ (right upper lobe bronchus), 0B950ZZ (right middle lobe bronchus), 0B960ZZ (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0B9M3ZZ (percutaneous), 0B9M4ZZ (percutaneous endoscopic), 0B9M7ZZ (via natural or artificial opening) and 0B9M8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0B9M00Z (drainage device).

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 907 (Other O.R.

Procedures for Injuries without CC/MCC), under the surgical categories “Major Chest Procedures” and “Other O.R. Procedures for Injuries”.
