About 0BB57ZX

0BB57ZX is the ICD-10-PCS code for a excision procedure on the right middle lobe bronchus using a via natural or artificial opening approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to closed [endoscopic] biopsy of bronchus, the ICD-9-CM procedure title it maps to (33.24).

For a different body part, codes include 0BB17ZX (trachea), 0BB27ZX (carina), 0BB37ZX (right main bronchus), 0BB47ZX (right upper lobe bronchus), 0BB67ZX (right lower lobe bronchus), 0BB77ZX (left main bronchus) and 12 more.

The same procedure with a different approach is coded 0BB50ZX (open), 0BB53ZX (percutaneous), 0BB54ZX (percutaneous endoscopic) and 0BB58ZX (via natural or artificial opening endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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