About 03914ZZ
03914ZZ is the ICD-10-PCS code for a drainage procedure on the left internal mammary artery using a percutaneous endoscopic 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 puncture of artery, the ICD-9-CM procedure title it maps to (38.98).
For a different body part, codes include 03904ZZ (right internal mammary artery), 03924ZZ (innominate artery), 03934ZZ (right subclavian artery), 03944ZZ (left subclavian artery), 03954ZZ (right axillary artery), 03964ZZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03910ZZ (open) and 03913ZZ (percutaneous).
With a different device, use 039140Z (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.
