About 0YB10ZX
0YB10ZX is the ICD-10-PCS code for a excision procedure on the left buttock using an open approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of 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 0YB00ZX (right buttock), 0YB50ZX (right inguinal region), 0YB60ZX (left inguinal region), 0YB70ZX (right femoral region), 0YB80ZX (left femoral region), 0YB90ZX (right lower extremity) and 11 more.
The same procedure with a different approach is coded 0YB13ZX (percutaneous) and 0YB14ZX (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.
