For Clinicians
The cognitive screen that pays for the visit.
Every Medicare Annual Wellness Visit requires detection of cognitive impairment — 42 CFR §410.15. Most practices satisfy it with unstructured observation worth nothing in documentation and nothing in follow-on care. MemTrax turns that required element into a validated, three-minute, self-administered screen — and an abnormal result creates the documented medical necessity that unlocks the rest of the cognitive care pathway.
One screen. Four billable stages.
MemTrax isn't a cost center inside the AWV — it's the trigger for a documented, fully legitimate care cascade.

G0438 / G0439
The Annual Wellness Visit
MemTrax satisfies the required cognitive-detection element with a structured, validated instrument instead of undocumented observation. The patient completes it in the waiting room; the result is in the chart before you walk in.

CPT 96146
Automated test administration
MemTrax is precisely what this code describes: single automated instrument, patient self-administered, electronically scored.

CPT 99483
Cognitive Assessment & Care Plan
An abnormal screen documents medical necessity for a dedicated cognitive assessment visit — billable every 180 days, permanently telehealth-eligible, and one of the most underused codes in geriatric medicine.

Ongoing care management
A care plan opens the door to monthly Chronic Care Management and CMS's GUIDE dementia model — recurring, per-patient revenue for care your patients need anyway.
Documentation that defends itself.
Single-timepoint screens invite denials. MemTrax produces a longitudinal record — the same patient, the same validated task, tracked over years. Change over time is the strongest medical-necessity evidence there is, and your patients build it automatically with every visit.
Zero physician minutes.
Front desk hands the patient a tablet at check-in
Patient completes the 3-minute continuous-recognition test in the waiting room
Score, percentile, and trend land in the record automatically
You review one number and act only when it warrants action
Built on thirty years of memory science.
MemTrax is a continuous-recognition paradigm developed by Dr. J. Wesson Ashford — Director at the VA Palo Alto Health Care System, Clinical Professor at Stanford University, and Senior Research Scientist at the Stanford Aging Clinical Research Center. The test has been validated in peer-reviewed studies against standard instruments and normed on one of the largest cognitive datasets ever assembled.
