Citi Benefits Handbook
Using Your Prescription Drug ID Card
You must use your prescription drug ID card when purchasing drugs at a retail pharmacy.
Upon your enrollment, Express Scripts will receive your eligibility information. If you do not have an ID card, please ask your pharmacist to contact Express Scripts so they can attempt to process the prescription through your pharmacy insurance. You can print out a temporary ID card online at under "Health and Benefits." You can also download the ESI mobile app to access your virtual ID card.
If you do not use your ID card at network pharmacies, you must pay the entire cost of the prescription drug and then submit a claim form to be reimbursed. You will be reimbursed according to the Express Scripts contracted rate for the covered prescription drug after you have met the annual deductible and paid the applicable copay. To access a claim form, visit Citi Benefits Online at and select "Forms and Claims."
Send all completed claim forms to:
