What are Part D Tiers?
Part D plans will typically do what they can to try and lower costs. In order to do this, they will place the covered drugs into different tiers. Any drug that is listed in a lower tier will generally cost less than a drug in a higher tier.
Here is an example of what plan’s tiers may look like:
- Tier 1 – Has the lowest copayment and usually consists of generic prescriptions
- Tier 2 – Has a medium copayment with preferred, brand-name prescriptions
- Tier 3 – Has a high copayment with non-preferred, brand-name prescriptions
- Specialty Tier – Has the highest copayment with high-cost prescriptions
