A Letter of Guarantee (LOG) is a letter from your company/ insurer to the Hospital stating the amount the company/ insurer is paying for the patient, co-payment required from patient (if any) and other terms and conditions. The hospital will then bill your company/ insurer accordingly. Whether you need to settle the bill upon discharge will depend on the terms and conditions of your policy as stated in the LOG. Please note that the hospital has the right to reject a LOG if the company/ insurer does not have a credit facility with us.
