About 0WCQ7ZZ

0WCQ7ZZ is the ICD-10-PCS code for a extirpation procedure on the respiratory tract using a via natural or artificial opening approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from 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 0WCP7ZZ (gastrointestinal tract) and 0WCR7ZZ (genitourinary tract).

The same procedure with a different approach is coded 0WCQ0ZZ (open), 0WCQ3ZZ (percutaneous), 0WCQ4ZZ (percutaneous endoscopic), 0WCQ8ZZ (via natural or artificial opening endoscopic) and 0WCQXZZ (external).

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.
