Yes, Medicare can cover a Mini-Cog test when a clinician uses it to screen for cognitive impairment. However, Medicare does not list Mini-Cog as a separately covered benefit; coverage applies to the visit or cognitive-assessment service. Mini-Cog is a brief screening tool, not an Alzheimer's diagnostic test. A concerning result may support the need for a more thorough evaluation, which Medicare Part B can also cover.

Where Mini-Cog fits in Medicare coverage
Clinicians may use a brief cognitive test during a Medicare Annual Wellness Visit or a routine visit. The Alzheimer's Association includes Mini-Cog among the validated measures in its Medicare cognitive-care-planning toolkit. Medicare pays for the broader service rather than treating Mini-Cog as an independently covered procedure.
In practical terms, the relevant question is whether the screening occurs within a covered visit. If the screen suggests possible impairment, the clinician may recommend a separate appointment for detailed assessment and care planning. That follow-up can help establish or confirm a diagnosis such as dementia or Alzheimer's disease.
The Annual Wellness Visit option
medicare Part B covers a yearly Wellness Visit that includes an assessment for signs of cognitive impairment. According to Medicare.gov's yearly Wellness Visit guidance, the visit is available once every 12 months. The Wellness Visit costs nothing when the provider accepts assignment.
A Mini-Cog may be one part of the cognitive check, although the clinician can choose another validated screening method. A screening result does not automatically establish a diagnosis. Its purpose is to identify concerns that deserve closer review, especially when the patient or family has noticed changes in memory or thinking.
What a full Alzheimer's evaluation includes
When possible cognitive impairment is detected, Medicare covers a more thorough cognitive-assessment-and-care-planning visit. CMS identifies this service with billing code CPT 99483, and it may be billed separately from the Annual Wellness Visit. This evaluation goes well beyond Mini-Cog.
CMS describes the cognitive-assessment service as including several elements: For CPT 99483, an independent historian must attend. This may be a spouse, guardian, or another reliable person who can describe changes and help supply medical or daily-living information. Physicians, nurse practitioners, clinical nurse specialists, and physician assistants may provide the service.
- A detailed medical history and examination
- Assessment of everyday function and safety
- Medication review
- Screening for behavioral symptoms
- Review of caregivers and other social support
What you may have to pay
The preventive Annual Wellness Visit has no cost when the provider accepts Medicare assignment. The separate comprehensive cognitive-assessment visit follows different cost-sharing rules.
With Original Medicare, the Part B deductible generally applies, followed by 20% of the Medicare-approved amount. Medicare.gov notes that cognitive-assessment costs can vary based on provider assignment and any additional coverage. Before the appointment, ask the provider's office:.
- Whether it accepts Medicare assignment
- Whether the appointment is the Annual Wellness Visit or a separate cognitive assessment
- Whether CPT 99483 is expected to be billed
- Whether a spouse, guardian, or other reliable person must attend
- What your supplemental or other coverage may pay
How to use the result
Mini-Cog cannot diagnose Alzheimer's disease or rule it out. An abnormal score signals a need for more detailed cognitive and medical evaluation, while a seemingly normal score does not resolve continuing memory concerns.
Ask the clinician what the score means in context and whether a follow-up evaluation is appropriate. If CPT 99483 is planned, arrange for a reliable person who knows the patient's recent functioning to attend the appointment.
