About 3E0Q3AZ
3E0Q3AZ is the ICD-10-PCS code for a introduction procedure on the cranial cavity and brain using a percutaneous approach with stem cells, embryonic. 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 other cranial puncture, the ICD-9-CM procedure title it maps to (01.09).
For a different body part, codes include 3E033AZ (peripheral vein), 3E043AZ (central vein) and 3E0R3AZ (spinal canal).
The same procedure with a different approach is coded 3E0Q0AZ (open).
With a different device, use 3E0Q33Z (anti-inflammatory), 3E0Q36Z (nutritional substance), 3E0Q37Z (electrolytic and water balance substance), 3E0Q3BZ (anesthetic agent), 3E0Q3HZ (radioactive substance), 3E0Q3KZ (other diagnostic substance) and 2 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.
