About 0WCHXZZ
0WCHXZZ is the ICD-10-PCS code for a extirpation procedure on the retroperitoneum using an external approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to removal of other foreign body without incision from head and neck, the ICD-9-CM procedure title it maps to (98.22).
For a different body part, codes include 0WC1XZZ (cranial cavity), 0WC3XZZ (oral cavity and throat), 0WC9XZZ (right pleural cavity), 0WCBXZZ (left pleural cavity), 0WCCXZZ (mediastinum), 0WCDXZZ (pericardial cavity) and 5 more.
The same procedure with a different approach is coded 0WCH0ZZ (open), 0WCH3ZZ (percutaneous) and 0WCH4ZZ (percutaneous endoscopic).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
