About 04JY0ZZ

04JY0ZZ is the ICD-10-PCS code for a inspection procedure on the lower artery using an open 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 blood vessels, the ICD-9-CM procedure title it maps to (38.29).

The same procedure with a different approach is coded 04JY3ZZ (percutaneous), 04JY4ZZ (percutaneous endoscopic) and 04JYXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
