About 0G9G4ZX
0G9G4ZX is the ICD-10-PCS code for a drainage procedure on the left thyroid gland lobe using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to closed [percutaneous] [needle] biopsy of thyroid gland, the ICD-9-CM procedure title it maps to (06.11).
For a different body part, codes include 0G904ZX (pituitary gland), 0G914ZX (pineal body), 0G924ZX (left adrenal gland), 0G934ZX (right adrenal gland), 0G944ZX (bilateral adrenal glands), 0G964ZX (left carotid body) and 15 more.
The same procedure with a different approach is coded 0G9G0ZX (open) and 0G9G3ZX (percutaneous).
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.
