About 01R207Z

01R207Z is the ICD-10-PCS code for a replacement procedure on the phrenic nerve using an open approach with autologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or 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 01R107Z (cervical nerve), 01R407Z (ulnar nerve), 01R507Z (median nerve), 01R607Z (radial nerve), 01R807Z (thoracic nerve), 01RB07Z (lumbar nerve) and 6 more.

The same procedure with a different approach is coded 01R247Z (percutaneous endoscopic).

With a different device, use 01R20JZ (synthetic substitute) and 01R20KZ (nonautologous tissue 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.
