About 0B958ZX

0B958ZX is the ICD-10-PCS code for a drainage procedure on the right middle lobe bronchus using a via natural or artificial opening endoscopic 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 closed [endoscopic] biopsy of bronchus, the ICD-9-CM procedure title it maps to (33.24).

For a different body part, codes include 0B918ZX (trachea), 0B928ZX (carina), 0B938ZX (right main bronchus), 0B948ZX (right upper lobe bronchus), 0B968ZX (right lower lobe bronchus), 0B978ZX (left main bronchus) and 14 more.

The same procedure with a different approach is coded 0B950ZX (open), 0B953ZX (percutaneous), 0B954ZX (percutaneous endoscopic) and 0B957ZX (via natural or artificial opening).

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.
