About 02JY0ZZ

02JY0ZZ is the ICD-10-PCS code for a inspection procedure on the great vessel using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Exploratory thoracotomy, the ICD-9-CM procedure title it maps to (34.02).

For a different body part, codes include 02JA0ZZ (heart).

The same procedure with a different approach is coded 02JY3ZZ (percutaneous) and 02JY4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 673 (Other Kidney and Urinary Tract Procedures with MCC), under the surgical categories “Major Chest Procedures”, “Other Circulatory System O.R. Procedures”, “Other Kidney and Urinary Tract Procedures” and 4 more.

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