About 0BT20ZZ
0BT20ZZ is the ICD-10-PCS code for a resection procedure on the carina using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.
In plain terms, this corresponds to other repair and plastic operations on trachea, the ICD-9-CM procedure title it maps to (31.79).
For a different body part, codes include 0BT10ZZ (trachea), 0BT30ZZ (right main bronchus), 0BT40ZZ (right upper lobe bronchus), 0BT50ZZ (right middle lobe bronchus), 0BT60ZZ (right lower lobe bronchus), 0BT70ZZ (left main bronchus) and 13 more.
The same procedure with a different approach is coded 0BT24ZZ (percutaneous 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 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Major Chest Procedures”, “Other O.R. Procedures for Injuries” and 1 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
