About 0BBL7ZX

0BBL7ZX is the ICD-10-PCS code for a excision procedure on the left lung using a via natural or artificial opening 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 closed endoscopic biopsy of lung, the ICD-9-CM procedure title it maps to (33.27).

For a different body part, codes include 0BB17ZX (trachea), 0BB27ZX (carina), 0BB37ZX (right main bronchus), 0BB47ZX (right upper lobe bronchus), 0BB57ZX (right middle lobe bronchus), 0BB67ZX (right lower lobe bronchus) and 12 more.

The same procedure with a different approach is coded 0BBL0ZX (open), 0BBL3ZX (percutaneous), 0BBL4ZX (percutaneous endoscopic) and 0BBL8ZX (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), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC) and DRG 362 (Other Circulatory System O.R. Procedures without MCC), under the surgical categories “Other Respiratory System O.R. Procedures” and “Other Circulatory System O.R. Procedures”.

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