About D718B9Z

D718B9Z is the ICD-10-PCS code for a brachytherapy procedure on the lymphatics, inguinal using a low dose rate (LDR) approach with iodine 125 (I-125) (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 D710B9Z (bone marrow), D711B9Z (thymus), D712B9Z (spleen), D713B9Z (lymphatics, neck), D714B9Z (lymphatics, axillary), D715B9Z (lymphatics, thorax) and 2 more.

The same procedure with a different approach is coded D71899Z (high dose rate (HDR)).

With a different device, use D718B6Z (cesium 131 (cs-131)), D718B7Z (cesium 137 (cs-137)), D718B8Z (iridium 192 (ir-192)), D718BBZ (palladium 103 (pd-103)), D718BCZ (californium 252 (cf-252)) and D718BYZ (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.
