About 0Y910ZZ
0Y910ZZ is the ICD-10-PCS code for a drainage procedure on the left buttock using an open approach. 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 0Y900ZZ (right buttock), 0Y950ZZ (right inguinal region), 0Y960ZZ (left inguinal region), 0Y970ZZ (right femoral region), 0Y980ZZ (left femoral region), 0Y990ZZ (right lower extremity) and 11 more.
The same procedure with a different approach is coded 0Y913ZZ (percutaneous) and 0Y914ZZ (percutaneous endoscopic).
With a different device, use 0Y9100Z (drainage 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.
