About 0WWM37Z

0WWM37Z is the ICD-10-PCS code for a revision procedure on the perineum, male using a percutaneous approach with autologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other operations on male genital organs, the ICD-9-CM procedure title it maps to (64.99).

For a different body part, codes include 0WW037Z (head), 0WW237Z (face), 0WW437Z (upper jaw), 0WW537Z (lower jaw), 0WW637Z (neck), 0WW837Z (chest wall) and 5 more.

The same procedure with a different approach is coded 0WWM07Z (open), 0WWM47Z (percutaneous endoscopic) and 0WWMX7Z (external).

With a different device, use 0WWM30Z (drainage device), 0WWM31Z (radioactive element), 0WWM33Z (infusion device), 0WWM3JZ (synthetic substitute), 0WWM3KZ (nonautologous tissue substitute) and 0WWM3YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 709 (Penis Procedures with CC/MCC) and DRG 710 (Penis Procedures without CC/MCC), under the surgical category “Penis Procedures”.

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