About 0BN27ZZ

0BN27ZZ is the ICD-10-PCS code for a release procedure on the carina using a via natural or artificial opening 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 lysis of adhesions of trachea or larynx, the ICD-9-CM procedure title it maps to (31.92).

For a different body part, codes include 0BN17ZZ (trachea), 0BN37ZZ (right main bronchus), 0BN47ZZ (right upper lobe bronchus), 0BN57ZZ (right middle lobe bronchus), 0BN67ZZ (right lower lobe bronchus), 0BN77ZZ (left main bronchus) and 12 more.

The same procedure with a different approach is coded 0BN20ZZ (open), 0BN23ZZ (percutaneous), 0BN24ZZ (percutaneous endoscopic) and 0BN28ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), 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 categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Respiratory 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.
