About 0CHS8YZ

0CHS8YZ is the ICD-10-PCS code for a insertion procedure on the larynx using a via natural or artificial opening endoscopic 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0CHA8YZ (salivary gland) and 0CHY8YZ (mouth and throat).

The same procedure with a different approach is coded 0CHS0YZ (open), 0CHS3YZ (percutaneous) and 0CHS7YZ (via natural or artificial opening).

With a different device, use 0CHS81Z (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.
