The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DMY1 includes procedures performed to deliver other radiation to the breast, right. These ICD-10-PCS codes are used for inpatient documentation when radiation therapy of the right breast is provided that does not fall into more specific radiation procedure categories.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DMY17ZZ	Contact Radiation of Right Breast
DMY18ZZ	Hyperthermia of Right Breast
DMY1FZZ	Plaque Radiation of Right Breast

Typical Clinical Scenarios

A patient with locally advanced right-sided breast cancer is admitted for inpatient management after wide-field external beam radiation is deemed unsuitable and a focused contact radiation session is planned to deliver high-dose localized therapy to the tumor bed while minimizing exposure to surrounding tissues; the inpatient stay allows multidisciplinary coordination and monitoring for acute reactions during treatment. Typical codes: DMY17ZZ
An elderly patient with recurrent right breast superficial tumor involvement undergoes planned inpatient hyperthermia combined with radiation to enhance tumor radiosensitivity; inpatient admission is used because of comorbidities requiring close monitoring during the thermal adjunctive therapy. Typical codes: DMY18ZZ
A patient with a difficult-to-control right breast local recurrence receives plaque radiation placed adjacent to the lesion during a short inpatient stay to deliver localized brachytherapy when external techniques are not suitable; the procedure is performed to achieve cytoreduction while limiting systemic exposure. Typical codes: DMY1FZZ
