About 079B3ZZ

079B3ZZ is the ICD-10-PCS code for a drainage procedure on the lymphatic, mesenteric using a percutaneous approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

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

The same procedure with a different approach is coded 079B0ZZ (open), 079B4ZZ (percutaneous endoscopic) and 079B8ZZ (via natural or artificial opening endoscopic).

With a different device, use 079B30Z (drainage device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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