About D91DBB1

D91DBB1 is the ICD-10-PCS code for a brachytherapy procedure on the nasopharynx using a low dose rate (LDR) approach with palladium 103 (pd-103) (qualifier: unidirectional source).

For a different body part, codes include D910BB1 (ear), D911BB1 (nose), D913BB1 (hypopharynx), D914BB1 (mouth), D915BB1 (tongue), D916BB1 (salivary glands) 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.
