About 03910ZZ
03910ZZ is the ICD-10-PCS code for a drainage procedure on the left internal mammary artery using an open 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 03900ZZ (right internal mammary artery), 03920ZZ (innominate artery), 03930ZZ (right subclavian artery), 03940ZZ (left subclavian artery), 03950ZZ (right axillary artery), 03960ZZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03913ZZ (percutaneous) and 03914ZZ (percutaneous endoscopic).
With a different device, use 039100Z (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.
