About 0BST0ZZ

0BST0ZZ is the ICD-10-PCS code for a reposition procedure on the diaphragm using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

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 0BS10ZZ (trachea), 0BS20ZZ (carina), 0BS30ZZ (right main bronchus), 0BS40ZZ (right upper lobe bronchus), 0BS50ZZ (right middle lobe bronchus), 0BS60ZZ (right lower lobe bronchus) and 12 more.

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.
