Summary & Overview
CPT 1005T: Subscalp Continuous Bilateral EEG Device Programming
CPT code 1005T captures a focused, face‑to‑face clinical service: the review and adjustment of an implanted subscalp continuous bilateral EEG monitoring system for the first 15 minutes. This code reflects the growing role of implanted ambulatory neurophysiology devices in epilepsy and seizure management and is relevant nationally as device-based diagnostics and remote monitoring expand. Payers commonly involved in coverage and payment decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn what CPT code 1005T represents clinically and operationally, how it fits into service lines for neurology and device management, and the typical sites of service where the work occurs. The publication provides benchmark context, outlines common billing considerations, and summarizes clinical implications for programs managing implanted EEG systems. Data not available in the input for specific modifiers, associated taxonomies, ICD‑10 pairings, and related codes is noted where applicable.
Billing Code Overview
CPT code 1005T describes a clinician review and adjustment of an implanted subscalp continuous bilateral electroencephalography (EEG) monitoring system. The service covers the first 15 minutes of face‑to‑face contact and includes analyzing current device parameters and making programming changes to contact groups, gain, or bandpass filters.
-
Service type: Device programming and adjustment for implanted subscalp continuous bilateral EEG monitoring
-
Typical site of service: Outpatient clinic or ambulatory specialty device clinic, including device programming suites where face‑to‑face interaction with the patient and implanted system is performed
Clinical & Coding Specifications
Clinical Context
A 34-year-old patient with drug-resistant focal epilepsy presents for routine in-person follow-up after implantation of a subscalp continuous bilateral electroencephalography (EEG) monitoring system. The patient reports intermittent auras and breakthrough focal seizures despite antiseizure medications. The provider conducts a face-to-face visit to review recorded EEG data, assess the current device settings, interrogate signal quality, and perform real-time adjustments (for example, reassigning contact groups, changing amplifier gain, or modifying bandpass filter settings). The first 15 minutes of this clinician–patient encounter, during which the provider analyzes parameters and makes programming changes to optimize seizure detection and monitoring fidelity, is reported with 1005T. Typical workflow includes device interrogation, data review, discussion of seizure events and symptoms, programming changes as needed, and documentation of time spent and changes made. Typical site of service is an outpatient neurology clinic, epilepsy monitoring clinic, or ambulatory surgery center for device-related follow-up visits.

| Modifier | Description | When to Use |
|---|---|---|
24 | Unrelated E/M service by the same physician during a postoperative period | Use when the device programming visit is unrelated to the original implant procedure during the global period |
