About D9YCCZZ

D9YCCZZ is the ICD-10-PCS code for a other radiation procedure on the pharynx 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 D9Y4CZZ (mouth), D9YBCZZ (larynx) and D9YDCZZ (nasopharynx).

The same procedure with a different approach is coded D9YCFZZ (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.
