About 0WHQ43Z

0WHQ43Z is the ICD-10-PCS code for a insertion procedure on the respiratory tract using a percutaneous endoscopic approach with infusion device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

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 0WH043Z (head), 0WH143Z (cranial cavity), 0WH243Z (face), 0WH343Z (oral cavity and throat), 0WH443Z (upper jaw), 0WH543Z (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WHQ03Z (open), 0WHQ33Z (percutaneous), 0WHQ73Z (via natural or artificial opening) and 0WHQ83Z (via natural or artificial opening endoscopic).

With a different device, use 0WHQ41Z (radioactive element) and 0WHQ4YZ (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.
