About DW1LBB1

DW1LBB1 is the ICD-10-PCS code for a brachytherapy procedure on the lower back using a low dose rate (LDR) approach with palladium 103 (pd-103) (qualifier: unidirectional source).

For a different body part, codes include DW10BB1 (cranial cavity), DW11BB1 (head and neck), DW12BB1 (chest), DW13BB1 (abdomen), DW16BB1 (pelvic region), DW1KBB1 (upper back) and 5 more.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2020, effective October 1, 2019.
