About 0BNT4ZZ

0BNT4ZZ is the ICD-10-PCS code for a release procedure on the diaphragm 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 diaphragm, the ICD-9-CM procedure title it maps to (34.89).

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 0BNT0ZZ (open) and 0BNT3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical category “Major Chest Procedures”.

It was added in FY2018, effective October 1, 2017.
