Summary & Overview
CPT 0997T: Precuneus Magnetic Stimulation Treatment Planning
CPT code 0997T represents a specialized treatment-planning service for precuneus magnetic stimulation therapy that integrates MRI and EEG data to identify stimulation targets, dose, and pulse intensity, with a formal report produced. This service supports individualized neuromodulation approaches for brain-targeted therapies and is increasingly relevant as precision neuromodulation gains clinical traction nationally. Key payers assessed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context of the code, typical settings of care, and what topics payers commonly consider when evaluating coverage for advanced neuromodulation planning. The publication presents benchmarks where available, summarizes policy and coverage themes affecting access, and outlines clinical elements documented in treatment-planning reports. The content is intended for clinicians, billing specialists, and policy stakeholders seeking a succinct reference on the code’s clinical purpose and payer landscape. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 0997T describes treatment planning for precuneus magnetic stimulation therapy. The service uses MRI and EEG to analyze brain responses and determine the optimal stimulation location, dose, and intensity for magnetic pulses. A structured report documenting the planning results and recommended stimulation parameters is produced by the provider.
Service type: Treatment planning / Procedural mapping using neuroimaging and neurophysiology
Typical site of service: Outpatient imaging or neuromodulation clinic

Clinical & Coding Specifications
Clinical Context
A typical patient is a 35–65-year-old adult with treatment-resistant major depressive disorder who has been referred for targeted precuneus magnetic stimulation. The workflow begins with a neuromodulation specialist consultation to confirm indications, review prior medication and therapy trials, and obtain informed consent. Pre-procedure preparation includes scheduling a structural brain MRI and an EEG to capture baseline anatomy and cortical activity. On the day of planning, the provider reviews MRI and EEG data, performs neuronavigation and cortical mapping to identify the optimal precuneus target, and determines individualized stimulation parameters (pulse location, dose, frequency, and intensity). The provider documents analytic methods, the chosen coordinates or coil placement relative to anatomical landmarks, and an interpretation of EEG response patterns that informed dosing. A formal report is created that includes recommended stimulation location, pulse intensity, and follow-up scheduling. The finalized plan is used to guide subsequent therapeutic sessions or is submitted for prior authorization and billing for the planning service 0997T.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When billing only the physician or clinician’s professional work separate from technical components (e.g., if imaging/EEG technical services billed by facility) |
59 | Distinct procedural service | When the planning service is distinct from another service on the same day (avoid unbundling issues) |
24 | Unrelated evaluation and management service by the same physician during a postop period | When an unrelated E/M is provided during a global period unrelated to the planning procedure |
25 | Significant, separately identifiable E/M service by the same physician on the same day | When a separate evaluation is performed that is distinct from the planning activity |
76 | Repeat procedure or service by same physician | When the planning service is repeated later the same day |
77 | Repeat procedure by another physician | When another physician repeats the planning on the same day |
Q0 | Investigational clinical service provided in a clinical research study, non-therapeutic device | When the planning is part of a clinical research protocol meeting Q0 rules |
Q6 | Service furnished as part of clinical trial or research (non-therapeutic) | When billing rules require a research modifier for non-therapeutic planning services |
E1 | Upper left prosthetic region (site-specific example modifier group) | Rarely applicable; include only if site-specific billing rules require laterality/site reporting for procedural billing |
E4 | Lower left prosthetic region | Same note as E1; include only if payer requires site-level distinction |
