About 07BK4ZZ
07BK4ZZ is the ICD-10-PCS code for a excision procedure on the thoracic duct using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to other operations on thoracic duct, the ICD-9-CM procedure title it maps to (40.69).
For a different body part, codes include 07B04ZZ (lymphatic, head), 07B14ZZ (lymphatic, right neck), 07B24ZZ (lymphatic, left neck), 07B34ZZ (lymphatic, right upper extremity), 07B44ZZ (lymphatic, left upper extremity), 07B54ZZ (lymphatic, right axillary) and 14 more.
The same procedure with a different approach is coded 07BK0ZZ (open) and 07BK3ZZ (percutaneous).
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.
