About 0CHY7YZ

0CHY7YZ is the ICD-10-PCS code for a insertion procedure on the mouth and throat using a via natural or artificial opening 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 operations on trachea, the ICD-9-CM procedure title it maps to (31.99).

For a different body part, codes include 0CHA7YZ (salivary gland) and 0CHS7YZ (larynx).

The same procedure with a different approach is coded 0CHY0YZ (open), 0CHY3YZ (percutaneous) and 0CHY8YZ (via natural or artificial opening endoscopic).

With a different device, use 0CHY71Z (radioactive element) and 0CHY7BZ (intraluminal device, airway).

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.
