1) Professional home healthcare requires a doctor's prescription and is provided by Medicare-certified agencies through periodic visits from nurses and therapists. It is covered by Medicare or health insurance and the services are regulated. 2) Non-medical home care provides assistance from unskilled caregivers for tasks like bathing and housework through longer visits or live-in care determined by the customer. It is paid out-of-pocket and the customer has more control over the services. 3) The key differences are that professional home healthcare requires medical oversight while non-medical home care is more consumer-directed and provides sustained support without medical licensing.
