About 05P44MZ

05P44MZ is the ICD-10-PCS code for a removal procedure on the left innominate vein using a percutaneous endoscopic approach with neurostimulator lead. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to removal of peripheral neurostimulator lead(s), the ICD-9-CM procedure title it maps to (04.93).

For a different body part, codes include 05P04MZ (azygos vein) and 05P34MZ (right innominate vein).

The same procedure with a different approach is coded 05P40MZ (open), 05P43MZ (percutaneous) and 05P4XMZ (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), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and 5 more.

It was added in FY2017, effective October 1, 2016.
