About 0Y9B40Z

0Y9B40Z is the ICD-10-PCS code for a drainage procedure on the left lower extremity 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 other incision with drainage of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.04).

For a different body part, codes include 0Y9040Z (right buttock), 0Y9140Z (left buttock), 0Y9540Z (right inguinal region), 0Y9640Z (left inguinal region), 0Y9740Z (right femoral region), 0Y9840Z (left femoral region) and 11 more.

The same procedure with a different approach is coded 0Y9B00Z (open) and 0Y9B30Z (percutaneous).

With a different device, use 0Y9B4ZZ (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.
