About 0WC3XZZ

0WC3XZZ is the ICD-10-PCS code for a extirpation procedure on the oral cavity and throat 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 intraluminal foreign body from mouth without incision, the ICD-9-CM procedure title it maps to (98.01).

For a different body part, codes include 0WC1XZZ (cranial cavity), 0WC9XZZ (right pleural cavity), 0WCBXZZ (left pleural cavity), 0WCCXZZ (mediastinum), 0WCDXZZ (pericardial cavity), 0WCGXZZ (peritoneal cavity) and 5 more.

The same procedure with a different approach is coded 0WC30ZZ (open), 0WC33ZZ (percutaneous) and 0WC34ZZ (percutaneous endoscopic).

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.
