About 018F0ZZ

018F0ZZ is the ICD-10-PCS code for a division procedure on the sciatic nerve using an open approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to division or crushing of other cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.03).

For a different body part, codes include 01800ZZ (cervical plexus), 01810ZZ (cervical nerve), 01820ZZ (phrenic nerve), 01830ZZ (brachial plexus), 01840ZZ (ulnar nerve), 01850ZZ (median nerve) and 16 more.

The same procedure with a different approach is coded 018F3ZZ (percutaneous) and 018F4ZZ (percutaneous endoscopic).

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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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