About DDY48ZZ

DDY48ZZ is the ICD-10-PCS code for a other radiation procedure on the ileum using a hyperthermia approach with none (qualifier: none).

In plain terms, this corresponds to hyperthermia for treatment of cancer, the ICD-9-CM procedure title it maps to (99.85).

For a different body part, codes include DDY08ZZ (esophagus), DDY18ZZ (stomach), DDY28ZZ (duodenum), DDY38ZZ (jejunum), DDY58ZZ (colon) and DDY78ZZ (rectum).

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