The amount that may be due is dictated by your insurance plan. You may have a deductible to meet and/or co-insurance. Remember, your insurance plan is a contract between your insurance company, your employer and yourself. Please call the billing department at 301.663.9440, option 5 during normal business hours to help you estimate the amount based on our contract with your insurance company. You can also contact your insurance carrier for a detailed explanation of your benefits.
