About 0CJYXZZ
0CJYXZZ is the ICD-10-PCS code for a inspection procedure on the mouth and throat using an external 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 2 more, the ICD-9-CM procedure titles it maps to (24.19, 25.09, 28.19 and 2 more).
For a different body part, codes include 0CJAXZZ (salivary gland) and 0CJSXZZ (larynx).
The same procedure with a different approach is coded 0CJY0ZZ (open), 0CJY3ZZ (percutaneous), 0CJY4ZZ (percutaneous endoscopic), 0CJY7ZZ (via natural or artificial opening) and 0CJY8ZZ (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.
