About 07LL4CZ
07LL4CZ is the ICD-10-PCS code for a occlusion procedure on the cisterna chyli using a percutaneous endoscopic approach with extraluminal device. 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 07L04CZ (lymphatic, head), 07L14CZ (lymphatic, right neck), 07L24CZ (lymphatic, left neck), 07L34CZ (lymphatic, right upper extremity), 07L44CZ (lymphatic, left upper extremity), 07L54CZ (lymphatic, right axillary) and 12 more.
The same procedure with a different approach is coded 07LL0CZ (open) and 07LL3CZ (percutaneous).
With a different device, use 07LL4DZ (intraluminal device) and 07LL4ZZ (no 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.
