About 0CJS0ZZ
0CJS0ZZ is the ICD-10-PCS code for a inspection procedure on the larynx using an open 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 larynx, the ICD-9-CM procedure title it maps to (31.48).
For a different body part, codes include 0CJA0ZZ (salivary gland) and 0CJY0ZZ (mouth and throat).
The same procedure with a different approach is coded 0CJS3ZZ (percutaneous), 0CJS4ZZ (percutaneous endoscopic), 0CJS7ZZ (via natural or artificial opening), 0CJS8ZZ (via natural or artificial opening endoscopic) and 0CJSXZZ (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.
