About 0CJY3ZZ
0CJY3ZZ is the ICD-10-PCS code for a inspection procedure on the mouth and throat using a percutaneous 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 0CJA3ZZ (salivary gland) and 0CJS3ZZ (larynx).
The same procedure with a different approach is coded 0CJY0ZZ (open), 0CJY4ZZ (percutaneous endoscopic), 0CJY7ZZ (via natural or artificial opening), 0CJY8ZZ (via natural or artificial opening endoscopic) 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.
