About 0CJS3ZZ
0CJS3ZZ is the ICD-10-PCS code for a inspection procedure on the larynx 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 larynx, the ICD-9-CM procedure title it maps to (31.48).
For a different body part, codes include 0CJA3ZZ (salivary gland) and 0CJY3ZZ (mouth and throat).
The same procedure with a different approach is coded 0CJS0ZZ (open), 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.
