About 0BB28ZX

0BB28ZX is the ICD-10-PCS code for a excision procedure on the carina using a via natural or artificial opening endoscopic 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 trachea, the ICD-9-CM procedure title it maps to (31.44).

For a different body part, codes include 0BB18ZX (trachea), 0BB38ZX (right main bronchus), 0BB48ZX (right upper lobe bronchus), 0BB58ZX (right middle lobe bronchus), 0BB68ZX (right lower lobe bronchus), 0BB78ZX (left main bronchus) and 14 more.

The same procedure with a different approach is coded 0BB20ZX (open), 0BB23ZX (percutaneous), 0BB24ZX (percutaneous endoscopic) and 0BB27ZX (via natural or artificial opening).

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.
