Mail Order Pharmacy Information

MHBP offers mail order pharmacy benefits for prescription drugs that you take on an on-going basis.

You may also order your prescriptions by mail, internet or phone.

Maintenance and Long-Term Medications

A long-term maintenance medication is one that is taken regularly for chronic conditions or long-term therapy. A few examples include medications for managing high blood pressure, asthma, diabetes or high cholesterol. We have a program that allows members to have their 90-day supply medications delivered by mail. Or they can be picked up at any CVS Pharmacy®. Under the program, you may choose to get the initial prescription and two refills (30-day supply each) at a network retail pharmacy. Or you can use CVS Caremark® Mail Service Pharmacy. After the second refill at a retail pharmacy, more refills must be obtained either from a CVS retail pharmacy or through our mail order drug program. You’ll receive a letter after your second refill that describes your benefits and provides instructions on how to obtain more refills in up to a 90-day supply. If you have any questions about this program, call CVS Caremark Mail Service Pharmacy at 1-866-623-1441(TTY: 711).

Submitting Your Prescriptions

If you have a new mail order prescription that you will be using on an ongoing basis, ask your physician to write two prescriptions for you.
  • The first prescription should be for a 30-day supply that you can use right away at a retail pharmacy
  • The second prescription should be used for a three-month supply and should be sent to the mail-order pharmacy

Once you know that you’ll be using this medication on an ongoing basis, send the second prescription to the mail-order pharmacy using the Mail Order Form.  
Please note:
  • Follow the instructions on the form carefully to avoid any processing delays
  • Your order will be filled for the exact amount of medication prescribed by your doctor, so please check the quantity on your prescription slip to make sure it is correct
  • Allow three weeks for delivery of your mail order prescriptions

Prescription Drug Coverage Refills

You can order refills by phone, internet or mail. Order about three weeks before your prescription runs out to allow for processing and mailing time. Suggested refill dates will be included on the prescription you receive through mail order. This information will be on the prescription label.
