About 3E0X33Z
3E0X33Z is the ICD-10-PCS code for a introduction procedure on the cranial nerves using a percutaneous approach with anti-inflammatory. 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 other agent, except neurolytic, injection of other agent, except neurolytic and injection of steroid, the ICD-9-CM procedure titles it maps to (04.89, 04.89 and 99.23).
For a different body part, codes include 3E0133Z (subcutaneous tissue), 3E0233Z (muscle), 3E0333Z (peripheral vein), 3E0433Z (central vein), 3E0533Z (peripheral artery), 3E0633Z (central artery) and 22 more.
With a different device, use 3E0X3BZ (anesthetic agent) and 3E0X3TZ (destructive agent).
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.
