About 0KHY4YZ

0KHY4YZ is the ICD-10-PCS code for a insertion procedure on the lower muscle using a percutaneous 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 myotomy, the ICD-9-CM procedure title it maps to (83.02).

For a different body part, codes include 0KHX4YZ (upper muscle).

The same procedure with a different approach is coded 0KHY0YZ (open) and 0KHY3YZ (percutaneous).

With a different device, use 0KHY4MZ (stimulator lead).

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.
