CPT 0379T: Remote Visual Field Monitoring with Real-Time Data Analysis

Headline: CPT code 0379T defines a 30-day remote visual field monitoring service with real-time analysis and data storage

Lead: CPT code 0379T captures a monitored visual field examination for each eye that includes real-time data analysis, accessible data storage, and patient-initiated transmission to a remote surveillance center for up to 30 days. The code formalizes a bundled remote diagnostic and monitoring workflow, reflecting growing adoption of prolonged remote physiologic surveillance in ophthalmic care.

Why it matters: This code matters nationally as it standardizes reporting for extended, remotely monitored visual field assessments that combine clinical interpretation with technical monitoring and data management. Standardized coding supports consistent billing, program evaluation, and integration of remote diagnostic services into practice workflows.

Payers covered: Analysis commonly addresses commercial carriers and government programs, including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

What readers will learn: The publication provides benchmarks and coding guidance context for CPT code 0379T, summarizes payer coverage patterns and common modifiers, outlines expected sites of service and clinical context for use, and highlights policy and billing considerations relevant to remote diagnostic ophthalmic monitoring. Data not available in the input will be noted where applicable.

Billing Code Overview

CPT code 0379T describes a monitored visual field examination performed on each eye with concurrent real-time data analysis and accessible data storage. The service includes patient-initiated data transmission to a remote surveillance center for up to 30 days, with technical support and monitoring of the patient and data under the direction of the provider.

Service type: Remote diagnostic visual field monitoring with real-time analysis and data transmission
Typical site of service: Patient home or other outpatient non-facility settings where remote monitoring and data transmission are feasible

Clinical Context

A 68-year-old patient with known primary open-angle glaucoma and progressive peripheral vision loss is prescribed a home-based, continuous visual field monitoring service. The ophthalmology provider arranges for a portable visual field testing device that the patient uses daily at home. The device performs automated perimetry with real-time data analysis and securely transmits the patient-initiated test results to a remote surveillance center for up to 30 days. Technical support personnel monitor incoming data and alert the provider to significant changes per provider-directed thresholds. The clinical workflow includes: device setup and patient education in clinic; initiation of the 30-day home monitoring period; ongoing remote data review by technicians and escalation to the ophthalmologist for abnormal findings; documentation of monitoring initiation and any clinical decision-making based on transmitted data; and device return or deactivation at the end of the monitoring interval.
