About 3E0Q0SF

3E0Q0SF is the ICD-10-PCS code for a introduction procedure on the cranial cavity and brain using an open approach with gas (qualifier: other gas). 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 3E0Q3SF (percutaneous) and 3E0Q7SF (via natural or artificial opening).

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.
