About 0B990ZX
0B990ZX is the ICD-10-PCS code for a drainage procedure on the lingula bronchus using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

The same procedure with a different approach is coded 0B993ZX (percutaneous), 0B994ZX (percutaneous endoscopic), 0B997ZX (via natural or artificial opening) and 0B998ZX (via natural or artificial opening endoscopic).
