Medicare can cover a cognitive evaluation that includes a MoCA, but it does not guarantee coverage for a standalone MoCA test by name. MoCA is a brief screening tool for cognitive impairment; it may be one part of an Alzheimer's evaluation, not the entire evaluation. The key question is how the clinician uses and bills the test. Medicare Part B covers a separate cognitive-assessment visit that can establish or confirm dementia or Alzheimer's disease and produce a care plan, according to Medicare's cognitive-assessment coverage page.

When can Medicare cover the evaluation?
A Medicare beneficiary does not need an existing Alzheimer's diagnosis to qualify for the comprehensive service. Suspected cognitive impairment may be enough when a clinician identifies it during an Annual Wellness Visit or another routine visit. A brief cognitive test can occur during either of those visits.
If the results indicate impairment, the clinician may schedule a more detailed cognitive-assessment-and-care-plan visit. CMS directs clinicians to bill that comprehensive service under CPT 99483. The code identifies the full assessment and care-planning service—not simply the moca questionnaire—under CMS guidance for cognitive assessment and care-plan services.
Why isn't a MoCA alone enough?
Administering a MoCA does not, by itself, satisfy Medicare's requirements for CPT 99483. The covered service must include a detailed history and examination, functional and safety assessments, standardized symptom and dementia-staging tools, caregiver evaluation, advance-care planning, and a written care plan. MoCA Cognition also describes MoCA as a screening tool for mild cognitive impairment, not a test that can independently diagnose a cognitive disease.
An Alzheimer's evaluation therefore requires clinical interpretation and additional assessment. One Medicare contractor, Palmetto GBA, recognizes the short MoCA among documented cognitive tools in its 99483 policy. However, that local Medicare contractor policy does not create a nationwide guarantee that Medicare will pay for the full MoCA as a separate service.
What should you expect during the visit?
The comprehensive assessment is broader than a memory quiz. It examines cognitive symptoms alongside daily functioning, safety concerns, disease stage, caregiver needs, and future care planning. CMS requires an "independent historian"—someone who can provide information beyond the patient's own account.
This person may be a spouse, guardian, caregiver, or another person familiar with the patient's condition. The visit may take place in an office, at home, in a care facility, or through telehealth. Before the appointment, ask whether the clinician expects the independent historian to attend or participate remotely.
What will Original Medicare cost?
Under Original Medicare, the patient generally pays 20% of the Medicare-approved amount after meeting the Part B deductible. The final amount may also depend on whether the provider accepts assignment, where the service occurs, what the provider charges, and whether the patient has other insurance.
A billing office can help distinguish between a brief screening and a comprehensive CPT 99483 visit. Before the appointment, ask: Do not rely only on the appointment label "memory test" or "MoCA." Ask for the expected billing code and whether the service includes the complete cognitive assessment.
- Is the MoCA included in another covered visit or billed separately?
- Are you planning to bill CPT 99483?
- Does the appointment include the required assessment and written care plan?
- Do I need to bring a spouse, caregiver, guardian, or other independent historian?
- What amount might I owe under my coverage?
What if the screening result raises concern?
A MoCA result can support further evaluation, but it cannot establish Alzheimer's disease on its own. The clinician must interpret it with the person's history, examination, functional abilities, symptoms, and other assessment findings.
If a brief screening identifies impairment, ask whether a comprehensive cognitive-assessment-and-care-plan visit is appropriate. That service is available for suspected impairment, so the patient does not need to wait for a confirmed Alzheimer's diagnosis before discussing CPT 99483.
