Xenazine Medicare Formulary Information & Restrictions

Are there any restrictions on coverage?

Some Medicare plans have restrictions on coverage of tetrabenazine that may include:

Quantity Limits

Most Medicare plans restrict the amount of this prescription that can be purchased at one time. If you need to purchase a greater amount at one time, it may not be covered. Your options are to wait until that time period has passed before refilling, call your plan and ask for an exception, or consider using a GoodRx discount instead of Medicare to find the best price for this prescription.

Prior Authorization

Most Medicare plans will require you to obtain their authorization before they will provide coverage for this prescription. You’ll need to contact your plan and they may require you to have your doctor fill out paperwork indicating why you need this prescription. If you do not receive authorization or don’t want to go through this process, you may want to consider using a GoodRx discount instead of Medicare to find the best price for this prescription.

What drug tier is tetrabenazine typically on?

Tier 5

Medicare plans typically list tetrabenazine in Tier 5 of their formulary. Tier 5 drugs are usually non-preferred brand-name drugs. Tier 5 drugs cost more than Tier 1, 2, 3 and 4 drugs.
