About 0CBV4ZX

0CBV4ZX is the ICD-10-PCS code for a excision procedure on the left vocal cord using a percutaneous 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 larynx, the ICD-9-CM procedure title it maps to (31.43).

For a different body part, codes include 0CBM4ZX (pharynx), 0CBR4ZX (epiglottis), 0CBS4ZX (larynx) and 0CBT4ZX (right vocal cord).

The same procedure with a different approach is coded 0CBV0ZX (open), 0CBV3ZX (percutaneous), 0CBV7ZX (via natural or artificial opening) and 0CBV8ZX (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.
