About 0CHY01Z

0CHY01Z is the ICD-10-PCS code for a insertion procedure on the mouth and throat using an open approach with radioactive element. 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.

For a different body part, codes include 0CH701Z (tongue), 0CHA01Z (salivary gland) and 0CHS01Z (larynx).

The same procedure with a different approach is coded 0CHY31Z (percutaneous), 0CHY71Z (via natural or artificial opening) and 0CHY81Z (via natural or artificial opening endoscopic).

With a different device, use 0CHY0YZ (other device).

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 FY2021, effective October 1, 2020.
