About 0HJU0ZZ

0HJU0ZZ is the ICD-10-PCS code for a inspection procedure on the left breast using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Mastotomy and other diagnostic procedures on breast, the ICD-9-CM procedure titles it maps to (85.0 and 85.19).

For a different body part, codes include 0HJT0ZZ (right breast).

The same procedure with a different approach is coded 0HJU3ZZ (percutaneous), 0HJU7ZZ (via natural or artificial opening) and 0HJU8ZZ (via natural or artificial opening 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.
