About 0BBN4ZX

0BBN4ZX is the ICD-10-PCS code for a excision procedure on the right pleura using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to thoracoscopic pleural biopsy, the ICD-9-CM procedure title it maps to (34.20).

For a different body part, codes include 0BB14ZX (trachea), 0BB24ZX (carina), 0BB34ZX (right main bronchus), 0BB44ZX (right upper lobe bronchus), 0BB54ZX (right middle lobe bronchus), 0BB64ZX (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0BBN0ZX (open), 0BBN3ZX (percutaneous) and 0BBN8ZX (via natural or artificial opening endoscopic).

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.
