Defines BCBSNC coverage stance for quantitative EEG (including theta:beta ratio assessment) as a diagnostic aid for ADHD, cognitive impairment, and other mental health conditions, and states coverage for biofeedback for evaluation/diagnosis of attention-deficit disorder. Applies to commercial members and providers under Blue Cross Blue Shield - North Carolina.
Title changed to Quantitative Electroencephalography with updated description, policy guidelines, and expanded 'When Not Covered' list to include cognitive impairment and multiple mental health diagnoses.
Biofeedback for the evaluation and diagnosis of attention-deficit disorder was added as medically necessary.
Coverage Criteria — Quantitative Electroencephalography and Biofeedback
General coverage stance
Covered when ALL of the following are met
Source: policy statement and 'When Quantitative Electroencephalography is not covered'.
Biofeedback coverage for attention-deficit disorder
Covered when ALL of the following are met
Benefit applicability depends on member's benefit design; inclusion of codes does not guarantee reimbursement and BCBSNC may request medical records to determine medical necessity.
Quantitative electroencephalographic (EEG)-based assessment of the theta:beta ratio is not covered as a diagnostic aid for cognitive impairment and for all mental health diagnoses. Examples of conditions for which this assessment is excluded include, but are not limited to: major depressive disorder; substance use disorder diagnoses; post-traumatic stress disorder; conversion disorder with seizures or convulsions; anxiety disorder/generalized anxiety disorder; postconcussional syndrome; and autism spectrum disorders.
Quantitative EEG-based assessment of the theta:beta ratio is considered investigational and therefore not medically necessary when used as a diagnostic aid for attention-deficit/hyperactivity disorder (ADHD) and other neuropsychiatric disorders. BCBSNC does not provide coverage for investigational services or procedures.
Billing and Coding
Provider Actions, Documentation, and Review
Code reporting does not guarantee reimbursement; review may be required
Inclusion of a code in the Billing/Coding section does not guarantee reimbursement; BCBSNC may require prior authorization or medical record review to determine medical necessity for services (e.g., EEG codes 95812, 95813, 95816, 95819 and analysis code 95957). Providers should not assume payment solely because a code appears in the policy.
When submitting supporting letters, ensure they contain all required clinical details
When records are requested, include all specific information needed for the medical necessity review; letters of support/explanation are acceptable only if they contain the full required clinical details.
- Ensure documentation addresses clinical indications and any policy-specific criteria
- Do not submit letters alone unless they include all needed information
Include complete clinical records when documentation is requested
When BCBSNC requests documentation, include all clinical information required to make a medical necessity determination; letters of support or explanation may be helpful but are not sufficient unless they contain all required specifics.
- Provide full clinical records and specific information requested by BCBSNC
- Letters of support/explanation alone are insufficient unless they include all required information
Provide requested medical records promptly to avoid denial
BCBSNC may request medical records to determine medical necessity; lack of requested documentation or incomplete clinical information may result in denial of coverage.
- Failure to provide requested records or incomplete clinical information can trigger denial
- Respond promptly to record requests to support medical necessity determinations
Background
Quantitative electroencephalography (qEEG) is a technique that analyzes recorded brain electrical activity to derive numerical and topographic patterns of electrical signals. One commonly reported metric is the theta:beta ratio, which compares power in the theta frequency band relative to the beta band and has been proposed as an adjunctive measure to support diagnoses such as attention-deficit/hyperactivity disorder.
Although devices exist that measure the theta:beta ratio, BCBSNC considers use of qEEG-based theta:beta ratio assessment as investigational when applied as a diagnostic aid because evidence does not establish consistent diagnostic utility or improved net health outcomes. As stated in the policy, BCBSNC will not cover investigational procedures, while it will cover biofeedback for evaluation and diagnosis of attention-deficit disorder when determined to be medically necessary per member benefits and clinical documentation.

OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
