In New York, if someone is receiving home care through insurance (Medicare, Medicaid, or commercial), there will usually be more than one agency involved in the provision of care. This is because different types of home care providers are licensed to provide different services. For example, a Certified Home Health Agency (CHHA) may provide a patient with nursing and physical therapy, and sub-contract a licensed home care services agency (LHCSA) to provide a home health aide.
