About 0WC90ZZ
0WC90ZZ is the ICD-10-PCS code for a extirpation procedure on the right pleural cavity using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to other incision of pleura, the ICD-9-CM procedure title it maps to (34.09).
For a different body part, codes include 0WC10ZZ (cranial cavity), 0WC30ZZ (oral cavity and throat), 0WC40ZZ (upper jaw), 0WC50ZZ (lower jaw), 0WCB0ZZ (left pleural cavity), 0WCC0ZZ (mediastinum) and 7 more.
The same procedure with a different approach is coded 0WC93ZZ (percutaneous), 0WC94ZZ (percutaneous endoscopic) and 0WC9XZZ (external).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
