Mail Order Drugs

Get Your Prescriptions Delivered to Your Door!

You can get many of your Medicare Part D drugs sent to your home through mail. We work with Express Scripts® to offer these services to you. When you use these services, your eligible Medicare Part D drugs are mailed to your home. There is no charge for shipping if you use regular delivery.

Why Use Mail Order?

  • Convenience. Ordering is easy and your medicines are sent right to your home.
  • Quality and safety. Dedicated pharmacists look over each prescription to make sure it is correct. They also check to make sure you aren’t taking drugs that shouldn’t be taken together.
  • Guidance. If you have questions, you can call a pharmacist or technician for help 24 hours a day, 7 days a week.
  • Easy Refills. You can order refills by phone or online. It’s always a good idea to order your refills at least two weeks before your medicine runs out.

Can I Get My Drugs Through the Mail?

If you get both Medicare and Medicaid coverage from CareSource® MyCare Ohio (Medicare-Medicaid Plan) you qualify to use the mail order service for eligible Medicare Part D prescription drugs.

Not all Part D drugs are available through mail order. If a drug can be ordered through the mail, you will see the letters ‘MO’ next to the drug name in our online Find My Prescriptions tool and in our Preferred Drug List. This stands for mail order drug.

This service is not provided for any non-Part D drugs. In the Find My Prescriptions tool, non-Part D drugs are those in Tier 3. In the Preferred Drug List, non-Part D drugs are marked with an asterisk (*).

Automatic Refill Service

CareSource MyCare Ohio allows members to use an “automatic refill” service for their mail-order drugs. We will need your permission before we can send you a refill by mail. That way we make sure you get only the drugs you need.

Please allow up to 10 days from the time you place your order to receive delivery. If your mail order is delayed, please call ESI at 1-800-354-3903 to check on it. You can also check online at Just sign in and provide an order number, Rx number or member information.

Use a Network Pharmacy

If you use a mail-order pharmacy that is not in the CareSource MyCare Ohio network, your drug will not be covered. If your drug needs a prior authorization, the mail-order pharmacy will call your doctor. If the prescription is rejected or the drug is out of stock, the mail-order pharmacy will contact you. The pharmacy will make sure you get a two-week supply through a local retail pharmacy.
