What it looks for

What does a WAVi scan measure?

WAVi records what the brain is doing electrically and quantifies it against WAVi's built-in normative database. It looks for measured change on a repeatable protocol. The clinician interprets every read; WAVi does not diagnose any condition as a standalone test.

EEG rhythms

Resting brain-wave activity, awake and drowsy, recorded from a rapid-placement headset. Shows the distribution of rhythm by frequency band and region at this visit.

ERP / P300

The event-related potential to an auditory oddball task: amplitude and latency of the P300 cognitive-processing response, with reaction time recorded alongside it.

QEEG comparison

Quantitative analysis against WAVi's built-in, age-matched normative database, so a baseline and a retest compare on the same numbers and the patterns worth a clinician's attention stand out.

Cleared to aid in diagnosis (FDA 510(k) K213900). It does not diagnose any condition on its own. The clearance, the verbatim indication and coverage are under Clearance & coverage below.

Who benefits

Who orders it, and what they look at.

One protocol, read differently by specialty. Each use is an aid to your clinical judgment, captured the same way every visit so the retest is a true comparison.

Neurology

Resting rhythms and P300 amplitude and latency as a quantified baseline next to the exam, then the same protocol after treatment. The BMTG read comes back signed by a board-certified neurologist.

Neurology page →

Sports Medicine

A baseline on the same protocol when it is clinically indicated, then a retest after an event. Your clinical team makes the return-to-play call; WAVi documents the measured change between baseline and retest.

Sports Medicine page →

Psychiatry

P300 and reaction-time markers before a course of care (ALTMS or medication), then after. Attention and focus markers sit alongside the published theta/beta literature as context, not a test.

Pairs with ALTMS →

Geriatrics + Longevity

A cognitive baseline at the first visit, tracked on the same protocol over years. Pairs with TM-Flow autonomic data in the BMTG Cognitive Function Report, which documents measured data and does not diagnose.

Geriatrics page →

Integrative + Functional

Before-and-after data around a protocol (photobiomodulation, hydrogen, a nutrition plan), typically 4 to 6 weeks or 12 weeks apart, so the change is documented rather than described.

Integrative page →

Rehab

Longitudinal tracking through a program. The same protocol at each visit turns "I think I feel sharper" into a side-by-side trend the patient can see.

Rehab page →

PI Law, via BMTG

The referring provider orders a WAVi-only Post-Injury Brain Function Report, signed by a board-certified neurologist who can support deposition. Admissibility is decided by the court and varies by jurisdiction.

How the Scan Works

How does a WAVi scan work?

A trained tech runs it, not the physician. Consistent placement and protocol are what make the retest a real comparison, and the retest is why practices keep it: a baseline with nothing to compare against is a snapshot; two on the same protocol are a trend.

01

Headset placement

Rapid placement of multiple EEG electrodes in a routine clinical setting. Comfortable, gel-free saline sensors, no gel mess for the patient.

02

EEG + ERP capture

Resting EEG awake and drowsy, plus event-related potentials including the P300 cognitive-processing marker. Recorded the same way every visit.

03

QEEG analysis

Quantitative analysis against WAVi's built-in normative database surfaces the patterns worth a clinician's attention.

04

Report on the portal

Results return on TITN's HIPAA-compliant portal with template visuals, interpreted through BMTG. You get a read, not a raw waveform.

Retest cadence. Retest frequency is decided by your payer on documented medical necessity. Wellness programs: before and after treatment, typically 4 to 6 weeks or 12 weeks.

BMTG Interpretation

Who interprets a WAVi scan, and on which report?

Every WAVi scan can come back interpreted. BMTG, TITN's sister service, delivers two distinct reports. The Post-Injury Brain Function Report is signed by a board-certified neurologist; the Cognitive Function Report is read by a BMTG board-certified neurologist or by your own. Neither report diagnoses; each documents measured data a clinician interprets. You stay in your specialty.

Coverage and coding
  • The scan is billed under the standard codes for the services performed, and your payer decides each line. The physician's cognitive assessment visit is billed separately, only when it is performed and documented.
  • Coverage depends on your contractor's policy, the documented indication, the equipment and method, and the interpreting physician.
  • Ask us for the coverage checklist and the one page worksheet, and confirm every code with your certified coder before the first claim.

Read your contractor's policy in the CMS Medicare Coverage Database before billing.

What TITN claims: WAVi captures EEG and ERP data to aid the clinician in diagnosis. Coverage is decided by the payer on the documented indication.
What TITN does not claim: WAVi does not diagnose any condition as a standalone test and does not treat any condition; it records EEG and ERP measures the clinician interprets. Interpretation is the clinician's. The earlier K162460 Research EEG Desktop variant (subject to a 2023 Class 2 recall) is not the cleared system TITN places; the device on this page is K213900.
Common questions

WAVi, answered.

The questions physicians ask before they order the first scan.

Is WAVi FDA cleared, and what does the clearance cover?

Yes. WAVi is an FDA 510(k) cleared EEG and event-related-potential assessment system (K213900). The clearance covers acquisition, display, and storage of EEG and ERP data to aid in diagnosis. It is not a clearance to detect or diagnose any specific condition, and it is not a standalone diagnostic test. The clinician interprets the data and makes the clinical decision.

How is it coded, and is it covered?

Coverage is decided by your payer on the documented indication. WAVi is billed under the standard codes for the services performed, and the cognitive assessment visit is billed separately when it is performed and documented. Read your Medicare contractor's policy in the CMS Medicare Coverage Database and confirm every code with your certified coder before the first claim.

How long does a scan take, and who reads it?

About twenty minutes with the headset on, run by a trained tech rather than the physician. Placement uses gel-free saline sensors in a routine clinical setting, with no gel and no prep beyond seating the patient. A board-certified neurologist interprets the data and signs the report through BMTG. Credentials are on file, available on request. Ask your TITN contact, or email support@transitionitnow.com, for the credentials packet: board certification and licensure.

What is the difference between qEEG and a routine clinical EEG?

A routine clinical EEG is read visually for standard patterns, such as epileptiform activity, by an interpreting physician. Quantitative EEG digitizes the same recorded signal and compares features like band power statistically against a normative database. qEEG does not replace a diagnostic EEG ordered to rule out epilepsy; it adds quantified numbers that a baseline and a retest can be compared on.

What do P300 amplitude and latency actually measure?

P300 is an event-related potential recorded during an auditory oddball task, reflecting attention allocation and the speed of stimulus evaluation. WAVi records its amplitude and latency alongside reaction time. Reduced amplitude and prolonged latency are associated with cognitive slowing in several conditions, but these markers are not specific to any single disease and are interpreted by the clinician in context.

Can WAVi track change over time?

Yes. Every scan is quantified on the same protocol, so a baseline and a retest compare directly against each other rather than only against a population norm. That is the usual reason practices keep it: one scan is a snapshot, two on the same protocol are a trend. Retest frequency is decided by your payer on documented medical necessity.

How does baseline-and-retest testing work for concussion tracking?

A baseline is captured before injury or early in care, then the same protocol is repeated after a suspected event and compared against that patient's own baseline. WAVi documents the measured change. Your clinical team makes the return-to-play call; published guidance is clear that tools like this should not be used alone for diagnosis or return-to-play decisions.

Is a WAVi assessment the same as a full neuropsychological evaluation?

No. A WAVi scan is a brief, quantified EEG and ERP assessment; a neuropsychological evaluation is a comprehensive battery administered and interpreted by a neuropsychologist. They answer different questions. WAVi is a complementary data point next to the exam and the history, not a substitute where full neuropsychological testing is clinically indicated.

Are there reasons a patient should not have a WAVi scan?

Standard EEG-type limitations apply. Scalp wounds, lesions, or skin conditions at electrode sites can prevent good contact, and a patient who cannot sit reasonably still for the recording will not produce usable data. Eligibility is a clinical judgment for the ordering provider, made per the device documentation, not a blanket assumption that every patient can be scanned.

Can a WAVi report support a medical-legal case?

Downstream, yes. When a provider orders WAVi and shares the report with counsel, BMTG can produce a Post-Injury Brain Function Report with quantified neurodiagnostic documentation signed by a board-certified neurologist. Admissibility is decided by the court and varies by jurisdiction; some courts have excluded quantitative EEG evidence offered as proof of brain injury, so treat it as documentation, not as settled proof.
