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 DGY1 includes procedures performed to deliver other radiation therapies to the pineal body in the endocrine system. These ICD-10-PCS codes are used for inpatient documentation when radiation therapy is administered specifically to the pineal body for treatment of tumors or other disorders. Accurate coding within the ICD-10-PCS DGY1 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Pineal Body Other Radiation Procedure Overview

Procedures in this group involve delivering targeted radiation therapy to the pineal body within the endocrine system to treat neoplastic or other pathological conditions. These ICD-10-PCS codes represent other radiation operations directed at the pineal body and distinguish the radiation modality and delivery site for inpatient records. Accurate coding ensures the procedure is properly captured for clinical documentation and supports appropriate inpatient reimbursement.

When to Use

Use a code from this group when other radiation therapy is intentionally delivered to the pineal body as part of inpatient treatment. Codes are selected when documentation indicates radiation was targeted to the pineal body rather than a different intracranial or endocrine structure.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DGY17ZZ	Contact Radiation of Pineal Body
DGY18ZZ	Hyperthermia of Pineal Body
DGY1FZZ	Plaque Radiation of Pineal Body

Typical Clinical Scenarios

A middle-aged patient presents with progressive headaches, visual disturbances, and imaging demonstrating a localized pineal region neoplasm causing obstructive hydrocephalus; after stabilization and neurosurgical consult, inpatient care includes targeted radiation therapy to the pineal body as part of primary tumor control or adjuvant treatment. A focused contact radiation procedure is selected to deliver localized dose to the pineal lesion while minimizing exposure to surrounding brain structures. Typical codes: DGY17ZZ
An elderly patient with a recurrent pineal body tumor previously treated with external-beam therapy is admitted for planned inpatient management to receive a localized plaque-based radiation boost to the pineal region because of tumor proximity to critical structures and prior radiation limits. The inpatient procedure delivers plaque radiation directly to the pineal body to intensify local control in a controlled setting. Typical codes: DGY1FZZ
A young patient with a radioresistant pineal body neoplasm is admitted emergently for hyperthermia combined with radiation to enhance radiosensitivity after rapid clinical progression despite prior therapy; inpatient hyperthermia is applied specifically to the pineal body as an adjunct to radiotherapeutic management. Typical codes: DGY18ZZ
