About 0BJT0ZZ

0BJT0ZZ is the ICD-10-PCS code for a inspection procedure on the diaphragm 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 0BJ00ZZ (tracheobronchial tree), 0BJ10ZZ (trachea), 0BJK0ZZ (right lung), 0BJL0ZZ (left lung) and 0BJQ0ZZ (pleura).

The same procedure with a different approach is coded 0BJT3ZZ (percutaneous), 0BJT4ZZ (percutaneous endoscopic), 0BJT7ZZ (via natural or artificial opening), 0BJT8ZZ (via natural or artificial opening endoscopic) and 0BJTXZZ (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.
