About 0BU50KZ

0BU50KZ is the ICD-10-PCS code for a supplement procedure on the right middle lobe bronchus using an open approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

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 0BU10KZ (trachea), 0BU20KZ (carina), 0BU30KZ (right main bronchus), 0BU40KZ (right upper lobe bronchus), 0BU60KZ (right lower lobe bronchus), 0BU70KZ (left main bronchus) and 4 more.

The same procedure with a different approach is coded 0BU54KZ (percutaneous endoscopic) and 0BU58KZ (via natural or artificial opening endoscopic).

With a different device, use 0BU507Z (autologous tissue substitute) and 0BU50JZ (synthetic substitute).

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.
