About D91FB6Z

D91FB6Z is the ICD-10-PCS code for a brachytherapy procedure on the oropharynx using a low dose rate (LDR) approach with cesium 131 (cs-131) (qualifier: none).

For a different body part, codes include D910B6Z (ear), D911B6Z (nose), D913B6Z (hypopharynx), D914B6Z (mouth), D915B6Z (tongue), D916B6Z (salivary glands) and 5 more.

With a different device, use D91FB7Z (cesium 137 (cs-137)), D91FB8Z (iridium 192 (ir-192)), D91FB9Z (iodine 125 (I-125)), D91FBBZ (palladium 103 (pd-103)), D91FBCZ (californium 252 (cf-252)) and D91FBYZ (other isotope).

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 FY2021, effective October 1, 2020.
