ICD-10-PCS Code For Pituitary Gland: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DG00 includes procedures performed to provide beam radiation to structures in the Pituitary Gland. These ICD-10-PCS codes are used for inpatient documentation when external beam radiation therapy is delivered to the pituitary gland for treatment of tumors or other pituitary disorders. Accurate coding within the ICD-10-PCS DG00 group is essential for proper inpatient reimbursement, as it captures the radiation therapy performed and supports clinical documentation accuracy.

Pituitary Gland Beam Radiation Procedure Overview

This group includes beam radiation procedures directed at the pituitary gland within the endocrine system. These procedures deliver targeted external radiation beams to the pituitary gland to treat neoplastic or functional disorders. Accurate ICD-10-PCS coding for these procedures ensures inpatient records reflect the specific radiation therapy delivered and supports correct reimbursement and case mix assignment.

When to Use

Use a code from this group when a patient receives external beam radiation therapy directed at the pituitary gland during an inpatient stay. Select the code that matches the beam radiation procedure and any documented delivery details for accurate inpatient coding and billing purposes; follow facility documentation for specificity.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DG000ZZ	Beam Radiation of Pituitary Gland using Photons <1 MeV
DG001ZZ	Beam Radiation of Pituitary Gland using Photons 1 - 10 MeV
DG002ZZ	Beam Radiation of Pituitary Gland using Photons >10 MeV
DG003Z0	Beam Radiation of Pituitary Gland using Electrons, Intraoperative
DG003ZZ	Beam Radiation of Pituitary Gland using Electrons
DG005ZZ	Beam Radiation of Pituitary Gland using Neutrons
DG006ZZ	Beam Radiation of Pituitary Gland using Neutron Capture

Typical Clinical Scenarios

A 62-year-old patient with a newly diagnosed pituitary macroadenoma causing visual field deficits is admitted for planned inpatient external beam radiotherapy after neurosurgical evaluation determined residual tumor unsuitable for further resection. Focused high-energy photon beams are delivered to the pituitary gland to reduce tumor size and relieve optic chiasm compression. The procedure is selected as part of definitive local control when surgery is limited by tumor location or patient comorbidity. Typical codes: DG002ZZ
A 45-year-old patient presents emergently with acute pituitary apoplexy from a hemorrhagic pituitary tumor and undergoes initial stabilization and partial resection; because of residual tumor burden and proximity to critical structures, adjuvant intraoperative electron beam therapy is delivered during the same inpatient operative episode to the pituitary gland. The intraoperative electron beam aims to provide concentrated local control while minimizing dose to surrounding brain tissue. Typical codes: DG003Z0
A 55-year-old patient with a recurrent pituitary carcinoma previously treated with photon radiotherapy is readmitted for re-treatment planning due to progressive hormonal dysfunction and tumor growth. Given prior photon exposure and the need for a different modality to target resistant tumor tissue, neutron capture therapy is used in the inpatient setting to deliver beam radiation to the pituitary gland as a salvage approach. Typical codes: DG006ZZ
