About 0BBF0ZX

0BBF0ZX is the ICD-10-PCS code for a excision procedure on the right lower lung lobe using an open 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 open biopsy of lung, the ICD-9-CM procedure title it maps to (33.28).

For a different body part, codes include 0BB10ZX (trachea), 0BB20ZX (carina), 0BB30ZX (right main bronchus), 0BB40ZX (right upper lobe bronchus), 0BB50ZX (right middle lobe bronchus), 0BB60ZX (right lower lobe bronchus) and 15 more.

The same procedure with a different approach is coded 0BBF3ZX (percutaneous), 0BBF4ZX (percutaneous endoscopic), 0BBF7ZX (via natural or artificial opening) and 0BBF8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest 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 “Major Chest Procedures”, “Other Circulatory System O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and 3 more.

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