About 0W4N0K1

0W4N0K1 is the ICD-10-PCS code for a creation procedure on the perineum, female using an open approach with nonautologous tissue substitute (qualifier: penis). In ICD-10-PCS, creation means putting in or on biological or synthetic material to form a new body part that to the extent possible replicates the anatomic structure or function of an absent body part.

In plain terms, this corresponds to operations for sex transformation, not elsewhere classified, the ICD-9-CM procedure title it maps to (64.5).

With a different device, use 0W4N071 (autologous tissue substitute) and 0W4N0J1 (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 748 (Female Reproductive System Reconstructive Procedures), under the surgical category “Female Reproductive System Reconstructive Procedures”.

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