About 0WJ80ZZ

0WJ80ZZ is the ICD-10-PCS code for a inspection procedure on the chest wall using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on chest wall, pleura, and diaphragm, the ICD-9-CM procedure title it maps to (34.28).

For a different body part, codes include 0WJ00ZZ (head), 0WJ10ZZ (cranial cavity), 0WJ20ZZ (face), 0WJ30ZZ (oral cavity and throat), 0WJ40ZZ (upper jaw), 0WJ50ZZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WJ83ZZ (percutaneous), 0WJ84ZZ (percutaneous endoscopic) and 0WJ8XZZ (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) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical category “Other Respiratory System O.R. Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
