About 0BTT4ZZ
0BTT4ZZ is the ICD-10-PCS code for a resection procedure on the diaphragm using a percutaneous endoscopic 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 operations on thorax, the ICD-9-CM procedure title it maps to (34.99).
For a different body part, codes include 0BT14ZZ (trachea), 0BT24ZZ (carina), 0BT34ZZ (right main bronchus), 0BT44ZZ (right upper lobe bronchus), 0BT54ZZ (right middle lobe bronchus), 0BT64ZZ (right lower lobe bronchus) and 13 more.
The same procedure with a different approach is coded 0BTT0ZZ (open).
It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. 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 “Other Respiratory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It was added in FY2018, effective October 1, 2017.
