ICD-10-PCS Code For Pineal Body: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DG01 includes procedures performed to deliver beam radiation to the pineal body. These ICD-10-PCS codes are used for inpatient documentation when external beam radiation therapy is administered to treat neoplastic or other pathological conditions of the pineal body. Accurate coding within the ICD-10-PCS DG01 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Pineal Body Beam Radiation Procedure Overview

Procedures in this group involve delivery of targeted beam radiation to the pineal body, a component of the endocrine system. These treatments use external radiation beams to treat lesions or tumors affecting the pineal body. Accurate ICD-10-PCS coding matters for inpatient reimbursement because it documents the specific radiation therapy delivered and supports appropriate case mix and payment.

When to Use

Use a code from this group when a patient receives external beam radiation therapy specifically targeted to the pineal body during an inpatient stay. Codes apply when documentation indicates beam radiation was the modality used to treat a pineal body condition.

ICD-10-PCS Codes

7 rows

ICD-10-PCS Code	Description
DG010ZZ	Beam Radiation of Pineal Body using Photons <1 MeV
DG011ZZ	Beam Radiation of Pineal Body using Photons 1 - 10 MeV
DG012ZZ	Beam Radiation of Pineal Body using Photons >10 MeV
DG013Z0	Beam Radiation of Pineal Body using Electrons, Intraoperative
DG013ZZ	Beam Radiation of Pineal Body using Electrons
DG015ZZ	Beam Radiation of Pineal Body using Neutrons
DG016ZZ	Beam Radiation of Pineal Body using Neutron Capture

Typical Clinical Scenarios

A pediatric patient presents with progressive headaches, hydrocephalus, and MRI-confirmed pineal region germinoma causing obstructive symptoms; after ventricular drainage and neurosurgical stabilization, inpatient external beam radiation is planned as the primary tumor-directed therapy to control the neoplasm while avoiding further invasive resection. Typical codes: DG011ZZ, DG012ZZ
An adult patient with a documented pineal parenchymal tumor previously treated surgically now admitted electively for definitive adjuvant external beam therapy to the pineal body to reduce local recurrence risk; the inpatient stay is for coordinated radiotherapy planning, immobilization, and fractionated beam delivery. Typical codes: DG010ZZ, DG011ZZ
A patient with a recurrent pineal region malignancy and prior photon therapy develops radioresistant disease; inpatient management includes delivery of alternative beam modalities such as neutron or neutron capture therapy as part of salvage treatment when indicated by the multidisciplinary team. Typical codes: DG015ZZ, DG016ZZ
