The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DDY7 includes procedures performed to apply localized radiation to structures in the rectum. These ICD-10-PCS codes are used for inpatient documentation when a patient receives contact radiation therapy targeted to rectal tissue for treatment of cancer or other clinical indications.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DDY77ZZ	Contact Radiation of Rectum
DDY78ZZ	Hyperthermia of Rectum
DDY7CZZ	Intraoperative Radiation Therapy (IORT) of Rectum
DDY7FZZ	Plaque Radiation of Rectum

Typical Clinical Scenarios

An elderly patient with locally advanced rectal adenocarcinoma presents for planned inpatient admission to receive localized contact radiation to the rectal tumor as part of a multimodality treatment regimen to reduce tumor burden before surgery; the procedure is performed in a controlled operative setting to deliver focused radiation directly to rectal tissue. Typical codes: DDY77ZZ, DDY7CZZ
A middle-aged patient admitted urgently for severe bleeding from a recurrent rectal carcinoma that failed external beam therapy; after stabilization, inpatient contact plaque radiation is applied directly to the rectal mucosal surface to achieve hemostasis and local tumor control. Typical codes: DDY7FZZ, DDY77ZZ
A patient previously treated with external beam radiation develops a persistent local rectal tumor causing obstructive symptoms and is taken to the operating room for intraoperative contact radiation delivered at the time of surgical debulking to improve local control; this single-session intraoperative application targets remaining rectal tissue. Typical codes: DDY7CZZ, DDY77ZZ
