About 0BL34CZ

0BL34CZ is the ICD-10-PCS code for a occlusion procedure on the right main bronchus using a percutaneous endoscopic 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 0BL14CZ (trachea), 0BL24CZ (carina), 0BL44CZ (right upper lobe bronchus), 0BL54CZ (right middle lobe bronchus), 0BL64CZ (right lower lobe bronchus), 0BL74CZ (left main bronchus) and 3 more.

The same procedure with a different approach is coded 0BL30CZ (open) and 0BL33CZ (percutaneous).

With a different device, use 0BL34DZ (intraluminal device) and 0BL34ZZ (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.
