About 0G9G40Z

0G9G40Z is the ICD-10-PCS code for a drainage procedure on the left thyroid gland lobe using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to aspiration of thyroid field, the ICD-9-CM procedure title it maps to (06.01).

For a different body part, codes include 0G9040Z (pituitary gland), 0G9140Z (pineal body), 0G9240Z (left adrenal gland), 0G9340Z (right adrenal gland), 0G9440Z (bilateral adrenal glands), 0G9640Z (left carotid body) and 15 more.

The same procedure with a different approach is coded 0G9G00Z (open) and 0G9G30Z (percutaneous).

With a different device, use 0G9G4ZZ (no device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
