About 009M30Z

009M30Z is the ICD-10-PCS code for a drainage procedure on the facial nerve using a percutaneous approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.04).

For a different body part, codes include 009030Z (brain), 009130Z (cerebral meninges), 009230Z (dura mater), 009330Z (epidural space, intracranial), 009430Z (subdural space, intracranial), 009530Z (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 009M00Z (open) and 009M40Z (percutaneous endoscopic).

With a different device, use 009M3ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator) and DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), under the surgical category “Peripheral, Cranial Nerve and Other Nervous System Procedures”.

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