Medicare is health insurance that covers people aged 65 or older, disabled people, and those with end stage renal disease (ESRD). Medicare has different parts that cover hospital services, outpatient clinical services like hemodialysis, Medicare Advantage plans, and prescription drug coverage. For dialysis, Medicare pays for 80% and patients pay 20% coinsurance. Medicaid and some private insurance plans may cover the remaining 20% that Medicare does not pay. The costs for outpatient hemodialysis will vary depending on a patient's specific Medicare, Medicaid, or private insurance coverage and plans.
