About 071K4Z3
071K4Z3 is the ICD-10-PCS code for a bypass procedure on the thoracic duct using a percutaneous endoscopic approach (qualifier: peripheral vein). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.
For a different body part, codes include 07104Z3 (lymphatic, head), 07114Z3 (lymphatic, right neck), 07124Z3 (lymphatic, left neck), 07134Z3 (lymphatic, right upper extremity), 07144Z3 (lymphatic, left upper extremity), 07154Z3 (lymphatic, right axillary) and 12 more.
The same procedure with a different approach is coded 071K0Z3 (open).
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 was added in FY2025, effective October 1, 2024.
