About 0BTM0ZZ

0BTM0ZZ is the ICD-10-PCS code for a resection procedure on the bilateral lungs using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other and unspecified pneumonectomy, the ICD-9-CM procedure title it maps to (32.59).

For a different body part, codes include 0BT10ZZ (trachea), 0BT20ZZ (carina), 0BT30ZZ (right main bronchus), 0BT40ZZ (right upper lobe bronchus), 0BT50ZZ (right middle lobe bronchus), 0BT60ZZ (right lower lobe bronchus) and 13 more.

The same procedure with a different approach is coded 0BTM4ZZ (percutaneous endoscopic).

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), DRG 165 (Major Chest 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 “Major Chest 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.
