About DTY1CZZ
DTY1CZZ is the ICD-10-PCS code for a other radiation procedure on the ureter using an intraoperative radiation therapy (IORT) approach with none (qualifier: none).
In plain terms, this corresponds to other radiotherapeutic procedure, the ICD-9-CM procedure title it maps to (92.29).
For a different body part, codes include DTY0CZZ (kidney), DTY2CZZ (bladder) and DTY3CZZ (urethra).
The same procedure with a different approach is coded DTY17ZZ (contact radiation), DTY18ZZ (hyperthermia) and DTY1FZZ (plaque radiation).
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.
