The out-of-pocket rental cost for a prescription bone growth stimulator varies significantly depending on health insurance coverage, Medicare provider fee schedules, and specific device models. Without insurance coverage, commercial rental rates or retail acquisition costs can range from $2,000 to over $4,000 per month. However, for patients with qualifying insurance or Medicare approval, out-of-pocket expenses are typically reduced to standard copays, coinsurance percentages, or deductible contributions.
