ICD-10-PCS Code For Stomach: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DDY1 includes procedures performed to deliver other radiation to structures in the stomach. These ICD-10-PCS codes are used for inpatient documentation when radiation therapy is administered to the stomach for treatment or palliation of gastrointestinal conditions. Accurate coding within the ICD-10-PCS DDY1 group is essential for proper inpatient reimbursement, as it captures the specific radiation therapy performed and supports clinical documentation accuracy.

ICD-10-PCS Codes

4 rows

ICD-10-PCS Code	Description
DDY17ZZ	Contact Radiation of Stomach
DDY18ZZ	Hyperthermia of Stomach
DDY1CZZ	Intraoperative Radiation Therapy (IORT) of Stomach
DDY1FZZ	Plaque Radiation of Stomach

Typical Clinical Scenarios

An elderly patient with locally advanced gastric adenocarcinoma presents for planned inpatient admission to receive adjunctive targeted radiation to the stomach as part of multimodality therapy following incomplete response to chemotherapy; the intent is definitive local tumor control with a focused intraoperative boost at time of surgical exploration to maximize dose to the gastric tumor while sparing surrounding organs, so an intraoperative radiation procedure to the stomach is performed. Typical codes: DDY1CZZ
A middle-aged patient with painful, bleeding gastric metastasis from melanoma is admitted for symptom control after failed endoscopic hemostasis; because the goal is palliative reduction of tumor bulk and bleeding with a localized surface radiation technique delivered directly to the stomach wall, a plaque radiation procedure to the stomach is used to control symptoms. Typical codes: DDY1FZZ
A hospitalized patient with a refractory, focal gastric tumor causing obstruction undergoes adjunctive contact radiation (brachytherapy contact application) to the stomach mucosa when external beam therapy is not feasible; the acute inpatient procedure is performed to palliate obstructive symptoms and provide local tumor cytoreduction. Typical codes: DDY17ZZ, DDY1FZZ
