A maintenance drug is one that is commonly used to treat a chronic or long-term condition and requires regular, daily use. Examples include drugs used to treat high blood pressure, heart disease, asthma and diabetes. Birth control is also considered a maintenance drug. For a complete list of maintenance drugs, click here.

If you currently have a prescription for a maintenance drug, as of January 1, 2015, you will need to have a prescription for a 90-day supply (not a 30-day supply) AND you will need to fill your prescription in one of three ways:

IMPORTANT: If you don’t use a 90-day prescription and try to get a 30-day prescription filled at a retail location other than one of the methods above, you will be charged the full retail cost (not the co-pay amount).


With Tier Zero, generic prescription medications used to treat chronic health conditions such as congestive heart failure (CHF), diabetes, high blood pressure, high cholesterol, tobacco addiction and more, are covered at 100%. For Tier Zero medications you pay $0 for a 30- or 90-day supply.
