About 0BJK4ZZ

0BJK4ZZ is the ICD-10-PCS code for a inspection procedure on the right lung using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Transpleural thoracoscopy, the ICD-9-CM procedure title it maps to (34.21).

For a different body part, codes include 0BJ04ZZ (tracheobronchial tree), 0BJ14ZZ (trachea), 0BJL4ZZ (left lung), 0BJQ4ZZ (pleura) and 0BJT4ZZ (diaphragm).

The same procedure with a different approach is coded 0BJK0ZZ (open), 0BJK3ZZ (percutaneous), 0BJK7ZZ (via natural or artificial opening), 0BJK8ZZ (via natural or artificial opening endoscopic) and 0BJKXZZ (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), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other Circulatory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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