Your medical insurance company may require you to buy only certain high quality medical products. You should make sure you buy such products only from a durable medical equipment store, or your insurance policy may become void and non-enforceable. Consult your insurance provider and read the policy terms before buying such equipment. There are certain criteria that these products must meet. It must be durable which means it should withstand repeated use. It must have a medical reason. The device is generally not useful for a person who is not sick or injured. The device is needed for use at home only.
Most such devices are expected to have at least three years of lifetime. These rules may vary or change if your area has been declared an emergency or disaster area. Consult your healthcare provider to learn how much these devices may cost. You may be able to cover some costs of these devices with the help of another insurance coverage.
