About 0B9N00Z

0B9N00Z is the ICD-10-PCS code for a drainage procedure on the right pleura using an open approach with drainage device. 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 incision of pleura, the ICD-9-CM procedure title it maps to (34.09).

For a different body part, codes include 0B9100Z (trachea), 0B9200Z (carina), 0B9300Z (right main bronchus), 0B9400Z (right upper lobe bronchus), 0B9500Z (right middle lobe bronchus), 0B9600Z (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0B9N30Z (percutaneous), 0B9N40Z (percutaneous endoscopic) and 0B9N80Z (via natural or artificial opening endoscopic).

With a different device, use 0B9N0ZZ (no device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
