About 04JY4ZZ

04JY4ZZ is the ICD-10-PCS code for a inspection procedure on the lower artery 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 percutaneous angioscopy, the ICD-9-CM procedure title it maps to (38.22).

The same procedure with a different approach is coded 04JY0ZZ (open), 04JY3ZZ (percutaneous) and 04JYXZZ (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.
