About 019C0ZX

019C0ZX is the ICD-10-PCS code for a drainage procedure on the pudendal nerve using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of cranial or peripheral nerve or ganglion, the ICD-9-CM procedure title it maps to (04.12).

For a different body part, codes include 01900ZX (cervical plexus), 01910ZX (cervical nerve), 01920ZX (phrenic nerve), 01930ZX (brachial plexus), 01940ZX (ulnar nerve), 01950ZX (median nerve) and 16 more.

The same procedure with a different approach is coded 019C3ZX (percutaneous) and 019C4ZX (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.
