About 0B9P0ZX

0B9P0ZX is the ICD-10-PCS code for a drainage procedure on the left pleura 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 other pleural biopsy, the ICD-9-CM procedure title it maps to (34.24).

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 0B9P3ZX (percutaneous), 0B9P4ZX (percutaneous endoscopic) and 0B9P8ZX (via natural or artificial opening endoscopic).

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.
