About D911B7Z

D911B7Z is the ICD-10-PCS code for a brachytherapy procedure on the nose using a low dose rate (LDR) approach with cesium 137 (cs-137) (qualifier: none).

In plain terms, this corresponds to Radioisotopic teleradiotherapy, the ICD-9-CM procedure title it maps to (92.23).

For a different body part, codes include D910B7Z (ear), D913B7Z (hypopharynx), D914B7Z (mouth), D915B7Z (tongue), D916B7Z (salivary glands), D917B7Z (sinuses) and 5 more.

The same procedure with a different approach is coded D91197Z (high dose rate (HDR)).

With a different device, use D911B6Z (cesium 131 (cs-131)), D911B8Z (iridium 192 (ir-192)), D911B9Z (iodine 125 (I-125)), D911BBZ (palladium 103 (pd-103)), D911BCZ (californium 252 (cf-252)) and D911BYZ (other isotope).

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

It has been valid since ICD-10-PCS took effect on October 1, 2015.
