About 01UB4KZ
01UB4KZ is the ICD-10-PCS code for a supplement procedure on the lumbar nerve using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.
In plain terms, this corresponds to cranial or peripheral nerve graft, the ICD-9-CM procedure title it maps to (04.5).
For a different body part, codes include 01U14KZ (cervical nerve), 01U24KZ (phrenic nerve), 01U44KZ (ulnar nerve), 01U54KZ (median nerve), 01U64KZ (radial nerve), 01U84KZ (thoracic nerve) and 6 more.
The same procedure with a different approach is coded 01UB0KZ (open) and 01UB3KZ (percutaneous).
With a different device, use 01UB47Z (autologous tissue substitute) and 01UB4JZ (synthetic substitute).
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 was added in FY2018, effective October 1, 2017.
