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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DW02 includes procedures performed to deliver beam radiation to structures in the chest. These ICD-10-PCS codes are used for inpatient documentation when therapeutic external beam radiation is administered to treat conditions of the chest. Accurate coding within the ICD-10-PCS DW02 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Chest Beam Radiation Procedure Overview

This procedure group includes beam radiation therapies directed to the chest anatomical region and targets thoracic structures within the anatomical regions body system. Procedures in this group involve delivering therapeutic ionizing radiation beams to treat malignant or benign conditions of the chest. Accurate ICD-10-PCS coding ensures inpatient documentation reflects the specific radiation therapy delivered and supports appropriate inpatient reimbursement.

When to Use

Use a code from this group when a patient receives external beam radiation therapy directed specifically at the chest during an inpatient encounter. Select the code that reflects the beam radiation procedure performed, the anatomical focus on the chest, and any applicable treatment parameters documented in the medical record.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DW020ZZ	Beam Radiation of Chest using Photons <1 MeV
DW021ZZ	Beam Radiation of Chest using Photons 1 - 10 MeV
DW022ZZ	Beam Radiation of Chest using Photons >10 MeV
DW023Z0	Beam Radiation of Chest using Electrons, Intraoperative
DW023ZZ	Beam Radiation of Chest using Electrons
DW024ZZ	Beam Radiation of Chest using Heavy Particles (Protons,Ions)
DW025ZZ	Beam Radiation of Chest using Neutrons
DW026ZZ	Beam Radiation of Chest using Neutron Capture

Typical Clinical Scenarios

An elderly patient with locally advanced non–small cell lung cancer is admitted for inpatient management of severe dyspnea and tumor-related hemoptysis. After stabilization, the oncology team delivers fractionated external beam photon radiation to the thoracic tumor to rapidly reduce tumor bulk and control bleeding while inpatient. Typical codes: DW021ZZ, DW022ZZ
A middle‑aged patient with a solitary pulmonary metastasis from colorectal cancer is scheduled for inpatient proton beam therapy as part of a multidisciplinary plan to achieve high‑precision tumor ablation with sparing of surrounding lung tissue. The procedure is performed electively during a planned admission to administer heavy‑particle beam radiation targeted to the chest lesion. Typical codes: DW024ZZ
A patient previously treated with external photon radiation for mediastinal lymphoma presents with recurrent localized disease and requires intraoperative electron boost radiation during a thoracic surgical procedure to address resistant tumor at the resection margin. The intraoperative electron beam is delivered during the same inpatient operative encounter to improve local control. Typical codes: DW023Z0, DW023ZZ
