Yes. Medicare Part B generally covers a neurological examination for an Alzheimer's evaluation when it is medically necessary.
Medicare does not offer a benefit with that exact name, but it covers eligible doctor services and a separate cognitive-assessment visit. A neurological examination checks cognition and physical functions such as balance, sensory responses, and reflexes. These findings can help a neurologist evaluate possible dementia.

Which Medicare benefit covers the examination?
A neurologist's outpatient examination generally falls under Part B when it is medically necessary to diagnose or treat a condition. Medicare describes this coverage as medically necessary doctor and health care provider services. Part B also covers a separate cognitive-assessment and care-plan visit.
This service can establish or confirm dementia or Alzheimer's disease and create a care plan. The distinction matters when scheduling. Ask whether the provider plans to bill for a standard specialist visit, the cognitive-assessment service, or both at separate appointments.
Is the yearly Wellness visit enough?
medicare requires a cognition assessment during the yearly Wellness visit. However, that visit focuses on prevention planning and is not a routine physical examination. If the initial assessment suggests impairment, Medicare covers a separate, more thorough evaluation for dementia, depression, anxiety, or delirium.
Medicare explains the difference between the Wellness visit and follow-up cognitive evaluation. Tell the clinician about memory or thinking changes rather than waiting for the annual visit. A separate diagnostic appointment may be necessary even if the person recently completed a Wellness visit.
What does the cognitive assessment include?
The covered cognitive-assessment service includes a detailed history and patient examination. It also involves focused observation of cognition, an assessment of daily function, medication review, and screening for behavioral symptoms. neurological testing may add information about both thinking and physical function.
The National Institute on Aging notes that dementia evaluations can include tests of balance, sensory response, and reflexes. These services overlap but are not identical. A neurologist's examination can support the diagnostic workup, while the cognitive-assessment visit also addresses care planning.
Who should attend the appointment?
For the cognitive-assessment and care-planning service billed under CPT 99483, an independent historian must be present. This can be a spouse, guardian, or another reliable person who knows the patient well.
That person can help describe changes the patient may not recognize or remember. Before the appointment, prepare: CMS says this service generally is billed separately from the yearly Wellness visit.
- Examples of changes in memory, judgment, behavior, or daily function
- A current medication list
- Questions about the diagnosis and care plan
- A reliable family member, guardian, or other informant
What could the evaluation cost?
After the Part B deductible, the patient generally pays 20% of the Medicare-approved amount for the separate cognitive-assessment visit. Additional tests or services can produce separate costs.
Medicare may not cover a service or may consider repeated services too frequent. Before the visit, ask the provider which service will be billed and whether additional testing is expected. This helps distinguish the neurologist's examination from the separate cognitive-assessment and care-planning service.
