A typical prosthetic limb costs anywhere between $15,000 and $90,000, depending on the type of limb desired by the patient. With medical insurance, a patient will typically pay 10%â50% of the total cost of a prosthetic limb, while the insurance company will cover the rest of the cost.
Hooks can cost only a few hundred dollars, but are limited functionally. Cosmetic prosthetic hands resemble the real thing, but are about as functional as a mannequin's hand. Electric models offer the best of both worlds, but are often prohibitively expensive. The hand, plus surgery to attach, can cost up to $60,000.
