About 3E0434Z
3E0434Z is the ICD-10-PCS code for a introduction procedure on the central vein using a percutaneous approach with serum, toxoid and vaccine. In ICD-10-PCS, introduction means putting in or on a therapeutic, diagnostic, nutritional, physiological, or prophylactic substance except blood or blood products.
In plain terms, this corresponds to injection of antidote, the ICD-9-CM procedure title it maps to (99.16).
For a different body part, codes include 3E0134Z (subcutaneous tissue), 3E0234Z (muscle), 3E0334Z (peripheral vein), 3E0534Z (peripheral artery), 3E0634Z (central artery), 3E0934Z (nose) and 1 more.
The same procedure with a different approach is coded 3E0404Z (open).
With a different device, use 3E0433Z (anti-inflammatory), 3E0436Z (nutritional substance), 3E0437Z (electrolytic and water balance substance), 3E043AZ (stem cells, embryonic), 3E043FZ (intracirculatory anesthetic), 3E043HZ (radioactive substance) and 6 more.
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.
