Quantity Limits (QL) are a Medicare Part D plan drug "utilization management restriction" which control the amount of a particular formulary drug that the Medicare Part D plan will cover during a specified time period. For example, your Medicare drug plan may state that a particular drug is limited to 30 pills per 30 days.
Like Prior Authorization (PA) or Step Therapy (ST), Quantity Limits are used by your Medicare Part D plan to manage plan members' health and medication safety.
What if you do not agree with your Medicare drug plan's Quantity Limit?
If your doctor writes a prescription for a quantity higher than your Medicare Part D plan's quantity limit, you can request a formulary exception from your drug plan - and, with your prescribing physician's assistance, ask your plan to cover the quantity of medication that is higher than the plan's quantity limit.
A formulary exception request is not automatically granted and if your Medicare Part D plan denies your request, you can appeal the Medicare plan's negative decision. You can read more about appealing your Medicare Part D plan's decision on this site
