About 0CHY71Z

0CHY71Z is the ICD-10-PCS code for a insertion procedure on the mouth and throat using a via natural or artificial opening 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 0CHA71Z (salivary gland) and 0CHS71Z (larynx).

The same procedure with a different approach is coded 0CHY01Z (open), 0CHY31Z (percutaneous) and 0CHY81Z (via natural or artificial opening endoscopic).

With a different device, use 0CHY7BZ (intraluminal device, airway) and 0CHY7YZ (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.
