CPT 99483 is covered for Medicare beneficiaries who are cognitively impaired, including those diagnosed with Alzheimer’s disease, other dementias, or mild cognitive impairment.
CPT 99483 is covered when the clinician, based on observation or corroborating information from patient/family/caregiver/others, determines the patient is cognitively impaired even if no formal diagnosis yet exists, provided documentation confirms impairment and the narrative history that prompted suspicion.
Coverage applies when a comprehensive visit results in a written care plan and includes all required elements of the 99483 service (cognition-focused evaluation, moderate-to-high MDM, functional assessment, dementia staging, medication reconciliation, neuropsychiatric evaluation, safety evaluation, caregiver identification/needs, advance care planning, and written care plan shared at initial education/support).
Medicare covers a separate cognitive assessment and care plan visit when cognitive impairment is detected as part of the Annual Wellness Visit (AWV).
Coverage is allowed when cognitive impairment is suspected during a routine visit based on direct clinical observation or a brief cognitive test.
Coverage is allowed when concern for cognitive impairment arises from information provided by the patient, family, friends, caregivers, or others.
