About 07LK0ZZ
07LK0ZZ is the ICD-10-PCS code for a occlusion procedure on the thoracic duct using an open approach. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.
In plain terms, this corresponds to ligation of thoracic duct, the ICD-9-CM procedure title it maps to (40.64).
For a different body part, codes include 07L00ZZ (lymphatic, head), 07L10ZZ (lymphatic, right neck), 07L20ZZ (lymphatic, left neck), 07L30ZZ (lymphatic, right upper extremity), 07L40ZZ (lymphatic, left upper extremity), 07L50ZZ (lymphatic, right axillary) and 12 more.
The same procedure with a different approach is coded 07LK3ZZ (percutaneous) and 07LK4ZZ (percutaneous endoscopic).
With a different device, use 07LK0CZ (extraluminal device) and 07LK0DZ (intraluminal device).
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.
