About 0CHS0YZ
0CHS0YZ is the ICD-10-PCS code for a insertion procedure on the larynx using an open approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.
In plain terms, this corresponds to other incision of larynx or trachea, the ICD-9-CM procedure title it maps to (31.3).
For a different body part, codes include 0CHA0YZ (salivary gland) and 0CHY0YZ (mouth and throat).
The same procedure with a different approach is coded 0CHS3YZ (percutaneous), 0CHS7YZ (via natural or artificial opening) and 0CHS8YZ (via natural or artificial opening endoscopic).
With a different device, use 0CHS01Z (radioactive element).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
