About XNU4356

XNU4356 is the ICD-10-PCS code for a supplement procedure on the thoracic vertebra using a percutaneous approach with synthetic substitute, mechanically expandable (paired) (qualifier: new technology group 6). 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.

For a different body part, codes include XNU0356 (lumbar vertebra).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R.

Procedures for Multiple Significant Trauma”.
