About 0BN73ZZ
0BN73ZZ is the ICD-10-PCS code for a release procedure on the left main bronchus using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to other repair and plastic operations on bronchus, the ICD-9-CM procedure title it maps to (33.48).
For a different body part, codes include 0BN13ZZ (trachea), 0BN23ZZ (carina), 0BN33ZZ (right main bronchus), 0BN43ZZ (right upper lobe bronchus), 0BN53ZZ (right middle lobe bronchus), 0BN63ZZ (right lower lobe bronchus) and 15 more.
The same procedure with a different approach is coded 0BN70ZZ (open), 0BN74ZZ (percutaneous endoscopic), 0BN77ZZ (via natural or artificial opening) and 0BN78ZZ (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.
