About 0BB20ZX
0BB20ZX is the ICD-10-PCS code for a excision procedure on the carina 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 larynx or trachea, the ICD-9-CM procedure title it maps to (31.45).
For a different body part, codes include 0BB10ZX (trachea), 0BB30ZX (right main bronchus), 0BB40ZX (right upper lobe bronchus), 0BB50ZX (right middle lobe bronchus), 0BB60ZX (right lower lobe bronchus), 0BB70ZX (left main bronchus) and 15 more.
The same procedure with a different approach is coded 0BB23ZX (percutaneous), 0BB24ZX (percutaneous endoscopic), 0BB27ZX (via natural or artificial opening) and 0BB28ZX (via natural or artificial opening endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), 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 categories “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Other Respiratory System O.R. Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
