About DDY4FZZ

DDY4FZZ is the ICD-10-PCS code for a other radiation procedure on the ileum using a plaque radiation 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 DDY0FZZ (esophagus), DDY1FZZ (stomach), DDY2FZZ (duodenum), DDY3FZZ (jejunum), DDY5FZZ (colon), DDY7FZZ (rectum) and 1 more.

The same procedure with a different approach is coded DDY47ZZ (contact radiation), DDY48ZZ (hyperthermia) and DDY4CZZ (intraoperative radiation therapy (IORT)).

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.
