About D01197Z
D01197Z is the ICD-10-PCS code for a brachytherapy procedure on the brain stem 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 D01097Z (brain), D01697Z (spinal cord) and D01797Z (peripheral nerve).
The same procedure with a different approach is coded D011B7Z (low dose rate (LDR)).
With a different device, use D01198Z (iridium 192 (ir-192)), D01199Z (iodine 125 (I-125)), D0119BZ (palladium 103 (pd-103)), D0119CZ (californium 252 (cf-252)) and D0119YZ (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.
