About 0BML0ZZ

0BML0ZZ is the ICD-10-PCS code for a reattachment procedure on the left lung using an open approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

In plain terms, this corresponds to other repair and plastic operations on lung, the ICD-9-CM procedure title it maps to (33.49).

For a different body part, codes include 0BM10ZZ (trachea), 0BM20ZZ (carina), 0BM30ZZ (right main bronchus), 0BM40ZZ (right upper lobe bronchus), 0BM50ZZ (right middle lobe bronchus), 0BM60ZZ (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
