Annual Wellness Visit Cognitive Test: What Medicare Covers and What to Expect

Why It Matters

Many older adults never receive structured cognitive screening unless they or a family member raises a concern. The annual wellness visit changes that dynamic by building a cognitive check into a visit most Medicare beneficiaries are already eligible for once every 12 months.

That matters because detection is the weak link. A commentary in JAMA Network Open notes that up to 60% of dementia cases go undiagnosed in primary care, and summarizes research finding that annual wellness visits were associated with a 21% increase in the likelihood of receiving a mild cognitive impairment diagnosis — with those diagnoses arriving roughly 76 days earlier than for people who did not have the visit.

The scale is large: the Alzheimer's Association estimates 7.4 million Americans age 65 and older are living with Alzheimer's in 2026. Because cognitive changes are usually gradual, subtle shifts can go unnoticed for years without periodic structured checks.

Key Facts at a Glance

• A listed component. Detecting cognitive impairment is a required element of the visit, alongside the health risk assessment and depression risk review.
• No single mandated test. Medicare does not name one instrument.
• Usually under five minutes. Brief primary-care tools are chosen partly for speed.
• No cost when assignment is accepted. No coinsurance, and the Part B deductible does not apply.
• Once every 12 months. Your first visit cannot fall within 12 months of Part B enrollment.
• Not a diagnosis. A flagged result triggers investigation, not a conclusion.

Does Medicare Require a Cognitive Test at the Annual Wellness Visit?

Medicare requires the detection of cognitive impairment, not a particular test. The Centers for Medicare & Medicaid Services lists "detect any cognitive impairments the patient may have" among the components of the annual wellness visit, and instructs clinicians to assess cognitive function by direct observation or reported observations from the patient, family, friends, and caregivers, while considering brief cognitive tests and risk factors.

The National Institute on Aging puts it plainly: assessment for cognitive impairment can be performed at any visit but is a required component of the Medicare annual wellness visit.

That flexibility is why two people can have very different experiences of the same benefit. One clinician may hand you a short pencil-and-paper task; another may ask a structured set of questions and note your answers. Both satisfy the requirement. Medicare bills the visit as HCPCS G0438 (first) or G0439 (subsequent), once per 12-month period, and it can be delivered via telehealth.

What the Screening Actually Involves

In practice, most clinicians use one or a combination of the following approaches.

Structured brief tools. The Alzheimer's Association points to instruments suited to primary care, including the Mini-Cog — described as a three-minute test combining a memory recall task and a scored clock-drawing task — the General Practitioner Assessment of Cognition (GPCOG), and the AD8, an eight-item informant interview designed to distinguish normal aging from mild dementia. A shared criterion across these tools is an administration time of five minutes or less. Our guide to how the Mini-Cog works walks through the format in more detail.

Clinical observation and patient history. Some clinicians observe conversation, recall, and follow-through during the visit, then ask you and a family member about changes in memory, daily function, and mood. Input from someone who knows you well adds context that no brief test can capture on its own.

Longer instruments, when time allows. A few practices use the Montreal Cognitive Assessment (MoCA), which is more detailed than a three-minute screen. It is clinician-administered and clinician-interpreted, and results are read in the context of your age, education, language, and health history. The National Institute on Aging endorses no specific tool; selection depends on the setting, the population, and the clinician's judgment.

What the Cognitive Portion of a Wellness Exam Asks About

Because Medicare requires detection but does not mandate a questionnaire, the exact questions vary from one office to the next. In practice, the check focuses on a few core areas:

• Short-term memory and recall — remembering a small amount of information over a brief interval.
• Orientation — awareness of time, date, and place.
• Attention and concentration — holding and manipulating information briefly.
• Executive function and visuospatial skill — often probed with a brief drawing task.
• Everyday function — whether managing medications, money, appointments, or driving has changed.
• Mood — depression risk factors are a separate required element of the visit and can affect cognitive performance.

Rather than a formal quiz, much of it may come from observation and from questions to you or a family member about everyday changes. You may also complete a health risk assessment beforehand; Medicare's minimum elements for that questionnaire include self-assessed health status, psychosocial risks such as stress and social isolation, behavioral risks, and activities of daily living.

Because the format is flexible, the cognitive step is easy to overlook. In one national analysis, fewer than one-third of beneficiaries reported receiving a structured cognitive assessment at their wellness visit (Health Affairs, 2020). It is reasonable to ask whether the cognitive portion was completed and what it showed.

How Long Does the Cognitive Part Take?

Short. The National Institute on Aging states that trained staff need only 10 minutes or less to initially assess a patient for cognitive impairment, and the brief instruments favored in primary care are designed to run in five minutes or less. The wellness visit as a whole typically takes longer — it also covers the health risk assessment, a medication and provider review, measurements, a screening schedule, and personalized advice.

If you are comparing this to other kinds of assessment, our guide to how long cognitive testing takes covers the full range, from three-minute screens to multi-hour neuropsychological evaluations.

What Does the Cognitive Screening Cost?

Nothing, in the ordinary case. Medicare.gov states that you pay nothing for the yearly wellness visit if your provider accepts assignment, and the Part B deductible does not apply. The cognitive check is part of that visit, not a separately billed add-on.

Two things can still generate a bill: additional services at the same appointment, where your clinician also evaluates or treats a specific problem and that portion is billed separately with coinsurance; and the follow-up cognitive assessment visit described below, which is a distinct service with its own cost sharing.

For a wider view of coverage rules, our guide on whether Medicare covers cognitive testing and the companion piece on how often Medicare will pay for cognitive testing explain frequency limits and what falls outside the preventive benefit.

How It Differs From a Full Cognitive Test

The wellness visit screening and a comprehensive cognitive test serve different purposes.

• Scope. The wellness visit check looks briefly at a few key functions. A full evaluation measures attention, memory, processing speed, language, and executive function in detail.
• Duration. Screening takes a few minutes; a full evaluation, 30 minutes to several hours.
• Purpose. Screening asks "is there a concern worth investigating?" A full evaluation asks "what is happening, how significant is it, and how has it changed?"
• Cost. The screening is bundled into the covered wellness visit. A detailed evaluation has its own coverage and cost rules.

Think of the screening as similar to a blood pressure reading — useful signal, but an abnormal result leads to investigation rather than a diagnosis.

Annual Wellness Visit vs. Welcome to Medicare Visit vs. Physical

These three are often confused, and the distinction determines both what happens and what you pay.

• Welcome to Medicare visit (IPPE). A one-time preventive visit available within the first 12 months of Part B coverage. Your first annual wellness visit cannot be billed within 12 months of it.
• Annual wellness visit. Covered once every 12 months. Medicare describes it as a conversation-based visit to build or update a prevention plan — explicitly "not a routine physical exam." This is the visit that carries the cognitive detection requirement.
• Routine physical exam. A hands-on exam performed without relation to a specific illness or complaint. Original Medicare does not cover it, so you pay out of pocket. Medicare Advantage plans must cover everything Original Medicare covers and may add extra benefits it does not, so check your own plan's benefits before assuming a physical is uncovered.

If you arrive expecting a physical and receive a conversation and a questionnaire, nothing has gone wrong — that is the benefit working as designed.

What Happens If the Screening Raises a Concern

A flagged cognitive screening does not mean you have dementia; it means your clinician has identified something worth a closer look. The National Institute on Aging notes that cognitive impairment in older adults has many possible causes — medication side effects, metabolic or endocrine dysfunction, delirium from an illness such as a urinary tract infection, depression, and dementia among them — and that some, including medication effects, are reversible.

Typical next steps include:

• A medication and supplement review.
• Lab work to check for thyroid problems, vitamin B12 deficiency, or infection.
• Screening for depression, sleep disorders, or hearing loss, each of which can depress test performance.
• A more detailed cognitive assessment, in primary care or with a specialist.
• Documented follow-up and repeat assessment at a later visit.

The U.S. Preventive Services Task Force issued an I statement in 2020: the evidence is insufficient to assess the balance of benefits and harms of screening asymptomatic community-dwelling adults 65 and older. That is not a recommendation against screening — the Task Force is explicit that clinicians should remain alert to early signs and evaluate patients when concerns arise.

What Is the Cognitive Assessment and Care Plan Visit?

This is the step most people do not know exists. When a clinician detects a possible problem, Medicare covers a separate, dedicated visit — billed under CPT code 99483 — to evaluate cognition properly and build a care plan.

According to CMS, the service typically involves about 60 minutes face-to-face with the patient and an independent historian, and covers a detailed history and exam, a cognition-focused evaluation, functional assessment of daily activities, standardized staging instruments, medication reconciliation, neuropsychiatric symptoms, safety, caregiver and social supports, and advance care planning. It can be billed separately from the wellness visit.

The cost differs from the screening: Medicare.gov states that after you meet the Part B deductible, you pay 20% of the Medicare-approved amount. It is worth asking whether this visit is being scheduled, because it is what turns a flagged screen into an actual plan.

Making the Most of Your Wellness Visit

A few minutes of preparation can make the cognitive portion more productive — not by rehearsing, but by bringing better information.

• Note any changes in memory, concentration, word-finding, or daily function over the past year, with examples.
• Bring a current medication and supplement list, including over-the-counter products.
• Consider bringing a family member who can serve as an informant; several brief tools are built around that perspective.
• Mention sleep problems, hearing or vision changes, recent illness, and mood, since all can affect performance.
• Ask which approach was used and what the result suggests, and keep a copy for comparison.

One thing not to do: practice or memorize screening tasks. These instruments work because your response is unrehearsed, and rehearsing removes the very signal your clinician is looking for. Our guide on how to prepare for cognitive testing covers the legitimate version of preparation.

Tracking results year over year turns a single data point into a trend, which is far more informative than any one score. If you want a more detailed starting point, our guide on baseline cognitive testing by age explains when that adds value beyond the wellness visit check.

You can decline the cognitive portion, as with any element of a preventive visit. It is worth weighing that against what the check is for: many causes of cognitive change are treatable, and identifying them earlier generally widens your options.

Does Medicare Advantage Handle This the Same Way?

Medicare Advantage plans must cover the annual wellness visit, and in practice their beneficiaries report cognitive assessment somewhat more often. The Health Affairs analysis found that 30% of Medicare Advantage enrollees reported a structured cognitive assessment at an annual wellness visit versus 23% of fee-for-service beneficiaries, with a wider gap for assessment at any health care visit — 40% versus 27%.

Plans differ more in what comes after the screening: network rules, referrals, and prior authorization shape how quickly you reach a specialist. Our comparison of how Medicare Advantage and Original Medicare differ on cognitive testing covers those mechanics.

Common Misconceptions

• "The wellness visit is just a physical exam." It is a preventive planning visit — health risk assessment, screening schedule, medication review, and a cognitive check.
• "A normal screening means nothing to worry about." A normal result is reassuring but does not rule out subtle or early changes, which is why periodic rechecking matters.
• "If the screening flags something, I have dementia." Many people with flagged screens turn out to have reversible causes or normal results on more detailed testing.
• "I would have been told if they did the cognitive part." Not necessarily — when done through observation and conversation, it can be invisible to the patient. Ask.

When the Wellness Visit Screening May Not Be Enough

The wellness visit check is a useful starting point, but brief tools are built for speed rather than sensitivity, and they can miss early or subtle changes — particularly in people with high educational attainment or strong compensatory strategies, whose everyday performance can mask a real decline. If you have a family history, specific risk factors, or persistent concerns that a five-minute check did not settle, a more comprehensive evaluation may be worthwhile. Our pillar guide on when to get cognitive testing walks through that decision, and our guide on when you should get your memory tested helps if you are noticing specific changes now.
