About 3E0Q305

3E0Q305 is the ICD-10-PCS code for a introduction procedure on the cranial cavity and brain using a percutaneous approach with antineoplastic (qualifier: other antineoplastic). 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 implantation of chemotherapeutic agent, the ICD-9-CM procedure title it maps to (00.10).

For a different body part, codes include 3E01305 (subcutaneous tissue), 3E02305 (muscle), 3E03305 (peripheral vein), 3E04305 (central vein), 3E05305 (peripheral artery), 3E06305 (central artery) and 21 more.

The same procedure with a different approach is coded 3E0Q005 (open) and 3E0Q705 (via natural or artificial opening).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator) and DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC), under the surgical category “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
