About 0BBL4ZX

0BBL4ZX is the ICD-10-PCS code for a excision procedure on the left lung 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 lung biopsy, the ICD-9-CM procedure title it maps to (33.20).

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 0BBL0ZX (open), 0BBL3ZX (percutaneous), 0BBL7ZX (via natural or artificial opening) 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), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other Circulatory System O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and 1 more.

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