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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DB02 includes procedures performed to deliver beam radiation to structures in the lung. These ICD-10-PCS codes are used for inpatient documentation when patients receive therapeutic beam radiation targeted at lung tissue for malignant or other radiotherapy-indicated conditions. Accurate coding within the ICD-10-PCS DB02 group is essential for proper inpatient reimbursement, as it captures procedure performed and supports clinical documentation accuracy.

Lung Beam Radiation Procedure Overview

This group includes beam radiation procedures directed at the lung within the respiratory system. These procedures deliver targeted external or internal beam radiation to treat malignant or other radiotherapy-indicated conditions of the lung. Accurate ICD-10-PCS coding of these radiation therapy procedures is important for inpatient documentation and reimbursement because it captures the specific therapy delivered and supports correct case mix assignment.

When to Use

Use a code from this group when a patient receives beam radiation specifically targeting the lung as part of inpatient treatment. Assign codes for the documented radiation therapy modality, target laterality, and session parameters as recorded in the medical record.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DB020ZZ	Beam Radiation of Lung using Photons <1 MeV
DB021ZZ	Beam Radiation of Lung using Photons 1 - 10 MeV
DB022ZZ	Beam Radiation of Lung using Photons >10 MeV
DB023Z0	Beam Radiation of Lung using Electrons, Intraoperative
DB023ZZ	Beam Radiation of Lung using Electrons
DB024ZZ	Beam Radiation of Lung using Heavy Particles (Protons,Ions)
DB025ZZ	Beam Radiation of Lung using Neutrons
DB026ZZ	Beam Radiation of Lung using Neutron Capture

Typical Clinical Scenarios

A patient with newly diagnosed, locally advanced non–small cell lung cancer is admitted for inpatient initiation of a planned external beam radiotherapy fraction as part of a combined-modality treatment with chemotherapy; treatment is delivered to the primary lung tumor using high-energy photons to achieve deeper tissue penetration and spare surrounding structures. A code from this group is used to document the therapeutic beam radiation session targeting lung tissue. Typical codes: DB022ZZ, DB021ZZ
An elderly patient with recurrent central lung tumor causing hemoptysis is hospitalized for symptomatic control and receives urgent palliative external beam radiation to the lung to reduce tumor bulk and bleeding; a lower-energy photon beam may be chosen to limit toxicity in adjacent tissues given the patients frailty and comorbidities. The inpatient procedure code captures the beam radiation modality and energy used. Typical codes: DB021ZZ, DB020ZZ
A patient undergoes intraoperative radiation therapy during surgical resection of a peripheral lung metastasis where an electron beam is delivered directly to the resection bed to decrease local recurrence risk; the radiation is administered in the operating room as part of the inpatient surgical admission. Typical codes: DB023Z0, DB023ZZ
