About 0BBT0ZZ
0BBT0ZZ is the ICD-10-PCS code for a excision procedure on the diaphragm using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to excision of lesion or tissue of diaphragm, the ICD-9-CM procedure title it maps to (34.81).
For a different body part, codes include 0BB10ZZ (trachea), 0BB20ZZ (carina), 0BB30ZZ (right main bronchus), 0BB40ZZ (right upper lobe bronchus), 0BB50ZZ (right middle lobe bronchus), 0BB60ZZ (right lower lobe bronchus) and 15 more.
The same procedure with a different approach is coded 0BBT3ZZ (percutaneous) and 0BBT4ZZ (percutaneous 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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Major Chest Procedures” and “Other Musculoskeletal System and Connective Tissue O.R. Procedures”.
It was added in FY2018, effective October 1, 2017.
