About D01797Z

D01797Z is the ICD-10-PCS code for a brachytherapy procedure on the peripheral nerve 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), D01197Z (brain stem) and D01697Z (spinal cord).

The same procedure with a different approach is coded D017B7Z (low dose rate (LDR)).

With a different device, use D01798Z (iridium 192 (ir-192)), D01799Z (iodine 125 (I-125)), D0179BZ (palladium 103 (pd-103)), D0179CZ (californium 252 (cf-252)) and D0179YZ (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.
