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