Medicare is a government health insurance program for senior citizens and some disabled Americans, while Medicaid is a state-administered healthcare program for qualifying low-income individuals and families. Medicare and Medicaid attorneys may perform several types of legal work in these areas. Medicaid and Medicare law firms can guide clients through the process of applying for the appropriate program or appealing a denied application. Lawyers can work with elderly clients to create estate plans that help ensure Medicaid eligibility, allowing for coverage of certain services (such as nursing home care) not typically provided by Medicare, and to appeal denied claims or reimbursements under either program. Doctors and other healthcare professionals should also have an established relationship with a law firm that has Medicare and Medicaid experience. Billing mistakes can lead to allegations of fraud, and a Medicare and Medicaid lawyer can help defend against these allegations.
