About 0WJL0ZZ

0WJL0ZZ is the ICD-10-PCS code for a inspection procedure on the lower back 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 incision of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.09).

For a different body part, codes include 0WJ00ZZ (head), 0WJ10ZZ (cranial cavity), 0WJ20ZZ (face), 0WJ30ZZ (oral cavity and throat), 0WJ40ZZ (upper jaw), 0WJ50ZZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WJL3ZZ (percutaneous), 0WJL4ZZ (percutaneous endoscopic) and 0WJLXZZ (external).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical category “Other Skin, Subcutaneous Tissue and Breast Procedures”.

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