About D91997Z

D91997Z is the ICD-10-PCS code for a brachytherapy procedure on the soft palate using a high dose rate (HDR) 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 D91097Z (ear), D91197Z (nose), D91397Z (hypopharynx), D91497Z (mouth), D91597Z (tongue), D91697Z (salivary glands) and 5 more.

The same procedure with a different approach is coded D919B7Z (low dose rate (LDR)).

With a different device, use D91998Z (iridium 192 (ir-192)), D91999Z (iodine 125 (I-125)), D9199BZ (palladium 103 (pd-103)), D9199CZ (californium 252 (cf-252)) and D9199YZ (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.
