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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DWY4 includes procedures performed to deliver other radiation to the hemibody anatomical region. These ICD-10-PCS codes are used for inpatient documentation when therapeutic radiation is administered to a hemibody region as part of cancer treatment or palliative care. Accurate coding within the ICD-10-PCS DWY4 group is essential for proper inpatient reimbursement, as it captures the specific radiation therapy performed and supports clinical documentation accuracy.

Hemibody Other Radiation Procedure Overview

Procedures in this group involve delivery of therapeutic radiation to the hemibody anatomical region and are classified under the Radiation Therapy section of the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS). These procedures target anatomical regions and are intended to treat malignant or other pathologic conditions through other radiation techniques rather than external beam fractionated therapy. Accurate coding of these procedures ensures inpatient records reflect the specific radiation therapy performed and supports appropriate reimbursement and case mix assignment.

When to Use

Use a code from this group when a patient receives therapeutic other radiation targeted to the hemibody during an inpatient encounter. These codes apply when the documented procedure specifies delivery of other radiation to a hemibody region rather than to a more specific organ or localized site.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DWY47ZZ	Contact Radiation of Hemibody
DWY48ZZ	Hyperthermia of Hemibody
DWY4FZZ	Plaque Radiation of Hemibody

Typical Clinical Scenarios

An elderly patient with widely metastatic breast carcinoma presents with severe, diffuse pain predominantly affecting the right half of the body (right hemibody) that is refractory to systemic analgesics and palliative focal radiation. The inpatient team coordinates regional palliative therapy to deliver contact radiation to the affected hemibody to reduce tumor burden and alleviate pain across multiple contiguous sites. Contact radiation is chosen because it allows localized superficial treatment over the involved hemibody tissue during the inpatient stay. Typical codes: DWY47ZZ
A middle-aged patient admitted for emergent management of a large cutaneous lymphoma involving extensive areas of the left hemibody with rapidly progressing ulceration and bleeding. Because the lesions are superficial and involve a broad contiguous hemibody surface, hyperthermia is applied adjunctively with other radiation approaches to increase tumor radiosensitivity during the inpatient course. The goal is to achieve prompt local control of widespread superficial disease when immediate, regionally targeted therapy is indicated. Typical codes: DWY48ZZ
A patient with ocular melanoma treated previously with localized plaque therapy develops multiple new small melanotic deposits across the ipsilateral hemibody that are deemed appropriate for regional plaque-based brachytherapy during a planned inpatient admission. Because therapy involves placement of radiation-delivering plaques to treat multiple contiguous areas within one hemibody region, plaque radiation is used to deliver targeted other radiation to the affected hemibody territory. This admission is for coordinated plaque application and monitoring given the extent of regional disease. Typical codes: DWY4FZZ
