About 3E0Q0BZ

3E0Q0BZ is the ICD-10-PCS code for a introduction procedure on the cranial cavity and brain using an open approach with anesthetic agent. 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).

The same procedure with a different approach is coded 3E0Q3BZ (percutaneous).

With a different device, use 3E0Q03Z (anti-inflammatory), 3E0Q06Z (nutritional substance), 3E0Q07Z (electrolytic and water balance substance), 3E0Q0AZ (stem cells, embryonic), 3E0Q0HZ (radioactive substance), 3E0Q0KZ (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 was added in FY2017, effective October 1, 2016.
