About 079L3ZX

079L3ZX is the ICD-10-PCS code for a drainage procedure on the cisterna chyli using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of lymphatic structure, the ICD-9-CM procedure title it maps to (40.11).

For a different body part, codes include 07903ZX (lymphatic, head), 07913ZX (lymphatic, right neck), 07923ZX (lymphatic, left neck), 07933ZX (lymphatic, right upper extremity), 07943ZX (lymphatic, left upper extremity), 07953ZX (lymphatic, right axillary) and 15 more.

The same procedure with a different approach is coded 079L0ZX (open), 079L4ZX (percutaneous endoscopic) and 079L8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 356 (Other Digestive System O.R. Procedures with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Circulatory System O.R. Procedures”, “Other Digestive System O.R. Procedures” and 6 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
