ICD-10-PCS Code For Brain Stem: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group D001 includes procedures performed to irradiate tissues in the brain stem. These ICD-10-PCS codes are used for inpatient documentation when external beam radiation therapy is delivered to the brain stem for treatment of tumors or other indications. Accurate coding within the ICD-10-PCS D001 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Brain Stem Beam Radiation Procedure Overview

Procedures in this ICD-10-PCS D001 group involve delivery of beam radiation to the brain stem within the central and peripheral nervous system. These interventions use targeted external radiation beams to treat neoplastic or other radiotherapy-responsive conditions affecting the brain stem. Accurate coding of beam radiation procedures to the brain stem ensures inpatient records reflect the specific anatomic target and supports correct reimbursement and quality reporting.

When to Use

Use a code from this group when external beam radiation is specifically directed at the brain stem during an inpatient stay. Select the code when documentation confirms beam radiation as the operative method and identifies the brain stem as the anatomical target.

ICD-10-PCS Code	Description
D0010ZZ	Beam Radiation of Brain Stem using Photons <1 MeV
D0011ZZ	Beam Radiation of Brain Stem using Photons 1 - 10 MeV
D0012ZZ	Beam Radiation of Brain Stem using Photons >10 MeV
D0013Z0	Beam Radiation of Brain Stem using Electrons, Intraoperative
D0013ZZ	Beam Radiation of Brain Stem using Electrons
D0014ZZ	Beam Radiation of Brain Stem using Heavy Particles (Protons,Ions)
D0015ZZ	Beam Radiation of Brain Stem using Neutrons
D0016ZZ	Beam Radiation of Brain Stem using Neutron Capture

Typical Clinical Scenarios

An elderly patient with a newly diagnosed intrinsic brain stem glioma presents with progressive cranial nerve deficits and worsening respiratory compromise; after multidisciplinary discussion and inpatient planning for definitive therapy, targeted external beam radiation is initiated to control tumor growth and relieve mass effect on vital brain stem structures. Treatment is delivered using high-energy photons suitable for deep-seated central nervous system lesions. Typical codes: D0012ZZ, D0011ZZ
A middle-aged patient with a recurrent brain stem metastasis previously treated with conventional radiotherapy is admitted electively for a planned course of highly conformal particle therapy (protons) to maximize dose to the lesion while minimizing exposure to adjacent normal brain stem tissue; inpatient stay is used for simulation, immobilization, and delivery of fractionated beam treatments. The procedure uses heavy particle beams tailored for the brain stem target. Typical codes: D0014ZZ
A young adult suffers acute neurologic deterioration from a radioresistant brain stem tumor for which intraoperative electron beam therapy is used as an adjunct at the time of a limited surgical debulking to provide immediate focal control at the resection bed; the patient remains inpatient for postoperative monitoring and further planned radiotherapy. This scenario involves intraoperative external beam electrons directed at the brain stem region. Typical codes: D0013Z0, D0013ZZ
