For Patients


Most standard insurance plans are accepted. Your Express Care visit will be billed as an office visit (not an emergency room visit). Payment of a copay may be required at the time of visit. Hospital and professional fees may also apply for additional services like medication/vaccine administration or lab/radiology services, among other procedures. You will be billed separately for any additional services.
