About 079830Z
079830Z is the ICD-10-PCS code for a drainage procedure on the right lymphatic, internal mammary using a percutaneous approach with drainage device. 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 079030Z (lymphatic, head), 079130Z (lymphatic, right neck), 079230Z (lymphatic, left neck), 079330Z (lymphatic, right upper extremity), 079430Z (lymphatic, left upper extremity), 079530Z (lymphatic, right axillary) and 15 more.
The same procedure with a different approach is coded 079800Z (open), 079840Z (percutaneous endoscopic) and 079880Z (via natural or artificial opening endoscopic).
With a different device, use 07983ZZ (no 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.
