About 0B9K4ZZ

0B9K4ZZ is the ICD-10-PCS code for a drainage procedure on the right lung using a percutaneous endoscopic 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 puncture of lung, the ICD-9-CM procedure title it maps to (33.93).

For a different body part, codes include 0B914ZZ (trachea), 0B924ZZ (carina), 0B934ZZ (right main bronchus), 0B944ZZ (right upper lobe bronchus), 0B954ZZ (right middle lobe bronchus), 0B964ZZ (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0B9K0ZZ (open), 0B9K3ZZ (percutaneous), 0B9K7ZZ (via natural or artificial opening) and 0B9K8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0B9K40Z (drainage device).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical category “Other Respiratory System O.R. Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
