About 0YJJ4ZZ
0YJJ4ZZ is the ICD-10-PCS code for a inspection procedure on the left lower leg using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring 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 0YJ04ZZ (right buttock), 0YJ14ZZ (left buttock), 0YJ54ZZ (right inguinal region), 0YJ64ZZ (left inguinal region), 0YJ74ZZ (right femoral region), 0YJ84ZZ (left femoral region) and 13 more.
The same procedure with a different approach is coded 0YJJ0ZZ (open), 0YJJ3ZZ (percutaneous) and 0YJJXZZ (external).
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.
