About 0B923ZX
0B923ZX is the ICD-10-PCS code for a drainage procedure on the carina using a percutaneous 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 trachea, the ICD-9-CM procedure title it maps to (31.44).
For a different body part, codes include 0B913ZX (trachea), 0B933ZX (right main bronchus), 0B943ZX (right upper lobe bronchus), 0B953ZX (right middle lobe bronchus), 0B963ZX (right lower lobe bronchus), 0B973ZX (left main bronchus) and 15 more.
The same procedure with a different approach is coded 0B920ZX (open), 0B924ZX (percutaneous endoscopic), 0B927ZX (via natural or artificial opening) and 0B928ZX (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.
