Yinstill does direct billing, therefore if your extended health covers acupuncture and/or Naturopathic medicine please bring along your policy card to your appointment. *Please note that with direct billing we also must have a credit card on file. A credit card will be charged for percentage of total or full amount when direct billing does not process for any reason. We can only process your primary insurance coverage at one time through our direct billing system. If you have secondary coverage you will need to submit your invoice to them manually to receive reimbursement of your payment.
