Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 99483 covers

A physician or other eligible practitioner evaluates a patient with cognitive impairment, often using an independent historian such as a family member or caregiver. The service brings together a cognition-focused history and examination, standardized cognitive assessment, review of daily function and decision-making capacity, medication reconciliation, and assessment of behavioral symptoms, mood, and safety concerns such as driving. It also identifies caregiver needs, addresses advance care planning, and produces a written plan with referrals when appropriate. The service is commonly furnished in an office or other outpatient setting, and may also take place in a home or residential setting.

Report 99483 for the completed assessment and care-planning service, not separately for each element. The encounter typically takes 50 minutes face-to-face with the patient and/or caregiver. Documentation should identify the historian when used, record assessment findings and functional and safety concerns, and show the resulting care plan and referrals. Keep the documentation specific to the patient; a cognitive screening result alone does not establish that the comprehensive service was performed.
