About 0WJN4ZZ

0WJN4ZZ is the ICD-10-PCS code for a inspection procedure on the perineum, female 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 other operations on female genital organs, the ICD-9-CM procedure title it maps to (71.9).

For a different body part, codes include 0WJ04ZZ (head), 0WJ14ZZ (cranial cavity), 0WJ24ZZ (face), 0WJ34ZZ (oral cavity and throat), 0WJ44ZZ (upper jaw), 0WJ54ZZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WJN0ZZ (open), 0WJN3ZZ (percutaneous) and 0WJNXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 749 (Other Female Reproductive System O.R. Procedures with CC/MCC) and DRG 750 (Other Female Reproductive System O.R. Procedures without CC/MCC), under the surgical category “Other Female Reproductive System O.R. Procedures”.

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