About 0WWQ41Z

0WWQ41Z is the ICD-10-PCS code for a revision procedure on the respiratory tract using a percutaneous endoscopic approach with radioactive element. 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 thorax, the ICD-9-CM procedure title it maps to (34.99).

For a different body part, codes include 0WW041Z (head), 0WW141Z (cranial cavity), 0WW241Z (face), 0WW441Z (upper jaw), 0WW541Z (lower jaw), 0WW641Z (neck) and 15 more.

The same procedure with a different approach is coded 0WWQ01Z (open), 0WWQ31Z (percutaneous), 0WWQ71Z (via natural or artificial opening), 0WWQ81Z (via natural or artificial opening endoscopic) and 0WWQX1Z (external).

With a different device, use 0WWQ43Z (infusion device) and 0WWQ4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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