Understanding your product's category is vital because it determines eligibility for financial assistance programs. Some programs may cover mobility aids, while others focus on home modifications. Knowing the category your product falls under can help you explore the right avenues for financial support.

Financial Assistance Programs

Medicare Coverage

Medicare Part B, which covers durable medical equipment, includes mobility equipment and select home devices. If you qualify, Medicare will reimburse you for 80% of the cost or the allowable amount set by Medicare, whichever is lower. For lift chairs, only the seat-lift mechanism is covered. Eligibility requires a doctor's assessment and a prescription for the necessary medical equipment. To qualify, the equipment must be deemed essential for daily activities and when more affordable options aren't available. Visit Medicare's website for comprehensive information.

Medicaid Assistance

Medicaid, a joint federal and state-funded insurance program, offers extensive medical care and support services for low-income, disabled individuals, and seniors. Qualification requirements vary from state to state, but generally, financial (income and assets) and medical (ability to perform daily activities) considerations are evaluated. In some states, specialized waivers are available to help individuals stay in or transfer to community-based settings instead of nursing homes, institutions, or hospitals. To learn more about Medicaid and available programs in your state, visit Medicaid's website.
