About 0B997ZZ
0B997ZZ is the ICD-10-PCS code for a drainage procedure on the lingula bronchus using a via natural or artificial opening 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 bronchus, the ICD-9-CM procedure title it maps to (33.0).
For a different body part, codes include 0B917ZZ (trachea), 0B927ZZ (carina), 0B937ZZ (right main bronchus), 0B947ZZ (right upper lobe bronchus), 0B957ZZ (right middle lobe bronchus), 0B967ZZ (right lower lobe bronchus) and 12 more.
The same procedure with a different approach is coded 0B990ZZ (open), 0B993ZZ (percutaneous), 0B994ZZ (percutaneous endoscopic) and 0B998ZZ (via natural or artificial opening endoscopic).
With a different device, use 0B9970Z (drainage 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.
