About 0Y900ZX
0Y900ZX is the ICD-10-PCS code for a drainage procedure on the right buttock using an open 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 other diagnostic procedures on skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.19).
For a different body part, codes include 0Y910ZX (left buttock), 0Y950ZX (right inguinal region), 0Y960ZX (left inguinal region), 0Y970ZX (right femoral region), 0Y980ZX (left femoral region), 0Y990ZX (right lower extremity) and 11 more.
The same procedure with a different approach is coded 0Y903ZX (percutaneous) and 0Y904ZX (percutaneous endoscopic).
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.
