About 0CBM7ZX
0CBM7ZX is the ICD-10-PCS code for a excision procedure on the pharynx 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 pharyngeal biopsy, the ICD-9-CM procedure title it maps to (29.12).
For a different body part, codes include 0CBR7ZX (epiglottis), 0CBS7ZX (larynx), 0CBT7ZX (right vocal cord) and 0CBV7ZX (left vocal cord).
The same procedure with a different approach is coded 0CBM0ZX (open), 0CBM3ZX (percutaneous), 0CBM4ZX (percutaneous endoscopic) and 0CBM8ZX (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.
