About XW0331B

XW0331B is the ICD-10-PCS code for a introduction procedure on the peripheral vein using a percutaneous approach with anitocabtagene autoleucel immunotherapy (qualifier: new technology group 11). In ICD-10-PCS, introduction means putting in or on a therapeutic, diagnostic, nutritional, physiological, or prophylactic substance except blood or blood products.

For a different body part, codes include XW0431B (central vein).

With a different device, use XW0330B (alpha1-proteinase inhibitor), XW033FB (other new technology therapeutic substance), XW033PB (gentamicin-eluting bone void filler), XW033QB (iloprost), XW033RB (letetresgene autoleucel) and XW033WB (AGN1 bone void filler).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 018 (Chimeric Antigen Receptor (CAR) T-Cell and Other Immunotherapies), under the surgical category “Chimeric Antigen Receptor (CAR) T-Cell and Other Immunotherapies”.
