About DDY4CZZ
DDY4CZZ is the ICD-10-PCS code for a other radiation procedure on the ileum 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 DDY1CZZ (stomach), DDY2CZZ (duodenum), DDY3CZZ (jejunum), DDY5CZZ (colon), DDY7CZZ (rectum) and DDY8CZZ (anus).
The same procedure with a different approach is coded DDY47ZZ (contact radiation), DDY48ZZ (hyperthermia) and DDY4FZZ (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.
