About 05W30MZ

05W30MZ is the ICD-10-PCS code for a revision procedure on the right innominate vein using an open approach with neurostimulator lead. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to implantation or replacement of peripheral neurostimulator lead(s), the ICD-9-CM procedure title it maps to (04.92).

For a different body part, codes include 05W00MZ (azygos vein) and 05W40MZ (left innominate vein).

The same procedure with a different approach is coded 05W33MZ (percutaneous), 05W34MZ (percutaneous endoscopic) and 05W3XMZ (external).

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 was added in FY2017, effective October 1, 2016.
