Patient Billing & Customer Service

Clear and accurate billing is a priority at Northwestern Lake Forest Hospital. We understand that healthcare bills can be confusing. We’ve assembled some helpful information about bills you may receive from Northwestern Lake Forest Hospital, any of its affiliated locations, or its physicians.

If you were treated at the hospital, you will receive a hospital bill that covers items such as room charges, medications, operating room fees or lab tests (if applicable), medical supplies and equipment. If you made a visit to the Emergency Department in Lake Forest, or the Emergency Center in Grayslake, you will incur charges for these services.

If you were treated in one of our affiliated locations, such as Gurnee, Vernon Hills or Lindenhurst, you may receive bills for lab tests and procedures, supplies, equipment or clinical and other staff fees.

Wherever you are treated, you may also receive a separate bill from physicians who were involved in your care.

Not all bills will come from Northwestern Lake Forest Hospital. Some bills will be mailed to you from doctors' offices and billing services. Read these bills carefully to find the phone number to call if you have a question about charges.
