About 01Q04ZZ

01Q04ZZ is the ICD-10-PCS code for a repair procedure on the cervical plexus using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to suture of cranial and peripheral nerves and other neuroplasty, the ICD-9-CM procedure titles it maps to (04.3 and 04.79).

For a different body part, codes include 01Q14ZZ (cervical nerve), 01Q24ZZ (phrenic nerve), 01Q34ZZ (brachial plexus), 01Q44ZZ (ulnar nerve), 01Q54ZZ (median nerve), 01Q64ZZ (radial nerve) and 16 more.

The same procedure with a different approach is coded 01Q00ZZ (open) and 01Q03ZZ (percutaneous).

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.
