About 0CJY8ZZ
0CJY8ZZ is the ICD-10-PCS code for a inspection procedure on the mouth and throat using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.
In plain terms, this corresponds to other diagnostic procedures on teeth, gums, and alveoli, other diagnostic procedures on tongue, other diagnostic procedures on tonsils and adenoids and 1 more, the ICD-9-CM procedure titles it maps to (24.19, 25.09, 28.19 and 1 more).
For a different body part, codes include 0CJS8ZZ (larynx).
The same procedure with a different approach is coded 0CJY0ZZ (open), 0CJY3ZZ (percutaneous), 0CJY4ZZ (percutaneous endoscopic), 0CJY7ZZ (via natural or artificial opening) and 0CJYXZZ (external).
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.
