Mail Order Prescriptions

Save time and money, and have your long-term medications delivered right to your door through the Express Scripts Home Delivery pharmacy. Ask your doctor or health provider to write you a prescription for up to 90 days, plus three refills (if applicable). Then:

  • Your doctor can fax it to Express Scripts at (800) 837-0959 or send it through their e-prescribing system, OR
  • Complete a mail-order form and send it, along with your prescription, to Express Scripts at the address on the form.
  • Please note: If you prefer to continue filling your prescriptions at your local retail pharmacy, you need to let ESI know before the fourth fill so you will not be charged more for your medication and for the amount you pay to continue to apply to your deductible and/or out-of-pocket. Additional details regarding the Select Home Delivery Active Choice Program are provided below.

You can download and print a copy of the form. Standard shipping is FREE! 

List of Covered Drugs and their Costs

Medications covered by the PSHB Standard and Basic Option plans, insured by Medical Mutual, are listed on our preferred drug list. This list is also known as a formulary. Please check the formulary to see how your medication is covered by your plan and at what copay tier. 

You can use the online formulary search tool to check coverage or compare prescription medication costs.

To use the tool:

  • Click “Go” under PSHB Open Season
  • Select the Standard or Basic plan
  • Select either “Formulary – look up drugs by name” or “Compare prescription medication costs” option

Prescription drugs must be filled through a network retail pharmacy (up to a 30-day supply) or the Express Scripts Home Delivery pharmacy (up to a 90-day supply).

Specialty Medications

Specialty medications must be filled at our contracted specialty pharmacies: Accredo and Gentry Health Services and are limited to a 30-day supply per fill. To see which medications are considered specialty, look for drugs noted as “Tier 4” in our 2025 Prescription Drug Formulary.

For more information, please review our Specialty Drug Solution flyer. 

Standard Plus Preventive Medications

Getting preventive care and taking preventive medications can be an important step people take to avoid many illnesses and maintain a good health. Medical Mutual has adopted the following list of preventive medications to support this goal. Find out more information here.

Select Home Delivery Active Choice Program

If you take any long-term prescription drugs, your plan offers the Select Home Delivery Active Choice program to help save you time and money. This program allows you to skip the line at the pharmacy and have your medications shipped directly to you. Refills will be sent in plenty of time before you run out. If you’d prefer to continue to pick up long-term prescriptions at your local pharmacy, you’ll need to notify Express Scripts of your preference before the fourth fill so you will not be charged more for your medication and for the amount you pay to continue to apply to your deductible and/or out-of-pocket. If you prefer to continue filling your prescriptions at your local retail pharmacy, you need to let Express Scripts know of your preference. Just call the Rx Information number listed on your member ID card. 

Contraceptive Coverage

With Medical Mutual’s Postal Service Health Benefits Program, you have access to contraceptive coverage at no cost to you. Please view our Preventive Care Benefits flyer for additional information on $0 coverage for preventive care benefits under the Affordable Care Act (ACA).

You can also reference the 2025 Prescription Drug Formulary to see which specific contraceptive medications are included at a $0 cost share. The Obstetrics & Gynecology section begins on page 165 and $0 ACA preventive medications are identified with Drug Tier 5 and category of ACA. 

Additional information regarding your contraceptive coverage can also be found by visiting the OPM website.
