ICD-10-PCS Code For Parathyroid Glands: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DG04 includes procedures performed to irradiate tissue in the parathyroid glands in the endocrine system. These ICD-10-PCS codes are used for inpatient documentation when external beam radiation is delivered to the parathyroid glands as part of a therapeutic radiation course. Accurate coding within the ICD-10-PCS DG04 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Parathyroid Glands Beam Radiation Procedure Overview

This procedure group includes beam radiation treatments directed at the parathyroid glands within the endocrine system. Procedures involve delivering targeted external beam radiation to parathyroid tissue to achieve therapeutic objectives. Accurate ICD-10-PCS coding matters for inpatient reimbursement because it documents the specific radiation procedure performed and supports appropriate case mix and payment determination.

When to Use

Use a code from this group when external beam radiation is intentionally delivered to the parathyroid glands during an inpatient stay. Do not use these codes for nonradiation treatments or for radiation directed at other endocrine structures.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DG040ZZ	Beam Radiation of Parathyroid Glands using Photons <1 MeV
DG041ZZ	Beam Radiation of Parathyroid Glands using Photons 1 - 10 MeV
DG042ZZ	Beam Radiation of Parathyroid Glands using Photons >10 MeV
DG043Z0	Beam Radiation of Parathyroid Glands using Electrons, Intraoperative
DG043ZZ	Beam Radiation of Parathyroid Glands using Electrons
DG045ZZ	Beam Radiation of Parathyroid Glands using Neutrons
DG046ZZ	Beam Radiation of Parathyroid Glands using Neutron Capture

Typical Clinical Scenarios

A middle-aged patient with recurrent primary hyperparathyroidism who has failed medical therapy and presents for a planned inpatient course of targeted external beam radiation to reduce hyperfunctioning parathyroid tissue prior to definitive surgery; radiation is delivered as a scheduled therapeutic session using photon energies appropriate for deep-seated endocrine tissue. Typical codes: DG041ZZ, DG042ZZ
An elderly patient with metastatic neck malignancy involving the parathyroid region is admitted for palliative inpatient radiation to control local tumor growth and associated hypercalcemia; the team delivers external beam photons of lower energy to palliate symptoms and preserve surrounding structures. Typical codes: DG040ZZ, DG041ZZ
A patient develops recurrent parathyroid tissue after prior surgery and presents urgently with symptomatic hypercalcemia not controlled medically; inpatient interdisciplinary care includes intraoperative electron beam radiation delivered during a surgical re-exploration to ablate residual parathyroid tissue. Typical codes: DG043Z0, DG043ZZ
