About 3E050GN

3E050GN is the ICD-10-PCS code for a introduction procedure on the peripheral artery using an open approach with other therapeutic substance (qualifier: blood brain barrier disruption). 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 disruption of blood brain barrier via infusion [BBBD], the ICD-9-CM procedure title it maps to (00.19).

For a different body part, codes include 3E030GN (peripheral vein), 3E040GN (central vein) and 3E060GN (central artery).

The same procedure with a different approach is coded 3E053GN (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.
