ICD-10-PCS Code For Eye: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group D820 includes procedures performed to deliver stereotactic radiosurgery to structures in the eye. These ICD-10-PCS codes are used for inpatient documentation when highly focused radiation is administered to treat intraocular tumors or other localized eye lesions. Accurate coding within the ICD-10-PCS D820 group is essential for proper inpatient reimbursement, as it captures the specialized radiation procedure performed and determines appropriate case mix and payment.

Eye Stereotactic Radiosurgery Procedure Overview

Procedures in this ICD-10-PCS D820 group involve stereotactic radiosurgery targeting the eye, using precisely focused radiation beams to treat intraocular lesions. These procedures fall under the Radiation Therapy section and specifically target the eye body part within the eye body system. Accurate coding of stereotactic radiosurgery procedures is important for inpatient reimbursement because it documents the specialized radiation treatment delivered and supports proper case mix assignment and payment.

When to Use

Use codes from this group when inpatient stereotactic radiosurgery is performed on the eye for localized tumors or other focal pathology requiring precision radiation. These codes apply when the radiation delivery meets stereotactic radiosurgery criteria and is documented in the inpatient record.

Typical Clinical Scenarios

A middle-aged patient with a solitary, well-circumscribed choroidal melanoma presents after biopsy confirmation and is admitted for planned definitive focal radiation because tumor location is adjacent to critical structures. The inpatient episode is used to coordinate stereotactic targeting, immobilization, and delivery of a single-session high-dose photon beam to maximize local control while minimizing collateral damage to the globe; a photon-based stereotactic radiosurgery code is therefore selected. Typical codes: D820DZZ
An elderly patient with a recurrent intraocular tumor previously treated with plaque brachytherapy is admitted for re-treatment when vision-threatening regrowth is confined to a small intraocular region; stereotactic particulate radiosurgery is chosen to deliver highly localized particle radiation with precise dosimetry. The inpatient stay facilitates multidisciplinary planning and delivery of particulate radiosurgery to spare surrounding ocular structures. Typical codes: D820HZZ
A young adult with a small, deeply situated optic nerve sheath tumor causing progressive visual loss is brought to inpatient care for a single-session, noninvasive gamma beam procedure that targets the lesion while preserving adjacent neural tissue. Stereotactic gamma beam radiosurgery is performed in the inpatient setting to achieve high conformality and steep dose falloff around the optic nerve complex. Typical codes: D820JZZ
