Summary & Overview
CPT 0378T: Remote Visual Field Monitoring with 30-Day Data Transmission
CPT code 0378T covers an extended remote visual field monitoring service in which a patient transmits visual field data to a remote surveillance center for up to 30 days while real-time analysis and accessible data storage occur, and a provider performs interpretation with a report. Nationally, this code reflects growing use of remote physiologic monitoring and telehealth-enabled diagnostic surveillance in ophthalmology and neurology, supporting continuous data capture outside traditional clinic visits.
Key payers noted in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service described by the code, the typical care setting for collection and interpretation, and the policy and billing context relevant to remote monitoring services. The publication outlines benchmarks for utilization where available, recent policy updates affecting remote monitoring reimbursement and documentation, and clinical context describing when extended visual field surveillance is used.
This summary is intended for clinicians, billing professionals, and policy analysts seeking a national-level briefing on the code’s purpose, applicable payers, and the types of information included in the full publication. Data not available in the input are noted where applicable in the detailed sections.
Billing Code Overview
CPT code 0378T describes an examination of the visual field of each eye that includes concurrent real-time data analysis and accessible data storage with patient-initiated data transmission to a remote surveillance center for up to 30 days, plus interpretation with report by the provider. The service involves remote physiologic monitoring of visual field data collected over an extended period and interpreted by a clinician.
-
Service type: Remote monitoring and interpretation of visual field testing over up to 30 days
-
Typical site of service: Remote monitoring with data transmission from the patient to a remote surveillance center; interpretation is performed by a provider (clinic or telehealth setting for review and reporting).
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a history of primary open-angle glaucoma is prescribed a 30-day ambulatory visual field monitoring service to assess diurnal and episodic visual field changes. The device is issued in clinic, with the patient instructed on self-administration at home. The monitoring system performs continuous real-time data analysis and securely transmits patient-initiated recordings to a remote surveillance center. The ophthalmologist or neuro-ophthalmologist reviews transmitted data periodically and provides formal interpretation and a written report at the conclusion of the monitoring period or sooner if clinically indicated. Typical workflow steps: initial clinic evaluation and order; device setup and patient education; remote data capture and transmission over up to 30 days with real-time analytics; provider review/interpretation of transmitted visual field data; documentation of findings and generation of the interpretation report; device return and follow-up visit for management decisions.
