Inquiring as to office policies in place concerning refunds to patients. With higher copayments, deductibles etc, we make every effort to accurately collect correct payments based upon insurance verification & fee schedules at the time of service. Inevitably there are overpayments; sometimes a few cents to larger dollar amounts. Deductibles & coinsurances paid at the time of service and reimbursed by insurance are refunded promptly, but how are most practices handling the smaller refunds? Is it acceptable to have a minimum amount required for refund and should this be a written policy?
