About 0BL70CZ

0BL70CZ is the ICD-10-PCS code for a occlusion procedure on the left main bronchus 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 ligation of bronchus, the ICD-9-CM procedure title it maps to (33.92).

For a different body part, codes include 0BL10CZ (trachea), 0BL20CZ (carina), 0BL30CZ (right main bronchus), 0BL40CZ (right upper lobe bronchus), 0BL50CZ (right middle lobe bronchus), 0BL60CZ (right lower lobe bronchus) and 3 more.

The same procedure with a different approach is coded 0BL73CZ (percutaneous) and 0BL74CZ (percutaneous endoscopic).

With a different device, use 0BL70DZ (intraluminal device) and 0BL70ZZ (no device).

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) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical category “Major Chest Procedures”.

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