About 0BNP4ZZ
0BNP4ZZ is the ICD-10-PCS code for a release procedure on the left pleura using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.
In plain terms, this corresponds to other operations on thorax, the ICD-9-CM procedure title it maps to (34.99).
For a different body part, codes include 0BN14ZZ (trachea), 0BN24ZZ (carina), 0BN34ZZ (right main bronchus), 0BN44ZZ (right upper lobe bronchus), 0BN54ZZ (right middle lobe bronchus), 0BN64ZZ (right lower lobe bronchus) and 15 more.
The same procedure with a different approach is coded 0BNP0ZZ (open) and 0BNP3ZZ (percutaneous).
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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
