About 0BL20CZ

0BL20CZ is the ICD-10-PCS code for a occlusion procedure on the carina using an open approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other operations on trachea, the ICD-9-CM procedure title it maps to (31.99).

For a different body part, codes include 0BL10CZ (trachea), 0BL30CZ (right main bronchus), 0BL40CZ (right upper lobe bronchus), 0BL50CZ (right middle lobe bronchus), 0BL60CZ (right lower lobe bronchus), 0BL70CZ (left main bronchus) and 3 more.

The same procedure with a different approach is coded 0BL23CZ (percutaneous) and 0BL24CZ (percutaneous endoscopic).

With a different device, use 0BL20DZ (intraluminal device) and 0BL20ZZ (no device).

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”, “Other Respiratory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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