About 3E030WK

3E030WK is the ICD-10-PCS code for a introduction procedure on the peripheral vein using an open approach with immunotherapeutic (qualifier: immunostimulator). 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 or infusion of other therapeutic or prophylactic substance, the ICD-9-CM procedure title it maps to (99.29).

For a different body part, codes include 3E040WK (central vein), 3E050WK (peripheral artery) and 3E060WK (central artery).

The same procedure with a different approach is coded 3E033WK (percutaneous).

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.
