About 0B577ZZ

0B577ZZ is the ICD-10-PCS code for a destruction procedure on the left main bronchus using a via natural or artificial opening approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to other local excision or destruction of lesion or tissue of bronchus, the ICD-9-CM procedure title it maps to (32.09).

For a different body part, codes include 0B517ZZ (trachea), 0B527ZZ (carina), 0B537ZZ (right main bronchus), 0B547ZZ (right upper lobe bronchus), 0B557ZZ (right middle lobe bronchus), 0B567ZZ (right lower lobe bronchus) and 12 more.

The same procedure with a different approach is coded 0B570ZZ (open), 0B573ZZ (percutaneous), 0B574ZZ (percutaneous endoscopic) and 0B578ZZ (via natural or artificial opening endoscopic).

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.
