Short answer: It depends on your insurance plan. Crestor (rosuvastatin) is often placed in a Tier 1 (or “generic‑equivalent”) slot, but many plans keep it in Tier 2 (or “brand‑name”) because it’s still a brand‑name drug. Check your specific formulary to be sure.

What do the tiers mean?
| Tier | Typical cost to you | Common drug types |
|------|---------------------|-------------------|
| Tier 1 | Lowest copay or coinsurance (sometimes $0) | Generics, many biosimilars, preferred brands |
| Tier 2 | Moderate copay/coinsurance | Preferred brand names or non‑generic meds |
| Tier 3 | Highest copay/coinsurance | Specialty drugs, high‑cost generics |
Some plans add additional tiers (e.g., “Tier 4” for high‑cost drugs) or use “preferred” and “non‑preferred” instead of numeric tiers.

Where does Crestor usually land?
- Brand‑name status: Crestor is the brand name for rosuvastatin. Because it’s a brand‑name product, many insurers put it in Tier 2 or “non‑preferred” even if a generic (rosuvastatin) exists.
- Generic availability: A generic version of rosuvastatin is available and often cheaper. Some plans place the generic in Tier 1 and the brand in Tier 2.
- Insurance variability: The exact tier can vary widely:
- Plan A (e.g., Blue Cross Blue Shield) might list Crestor as Tier 2.
- Plan B (e.g., Aetna) could place it in Tier 1 if they consider it a preferred brand.
- Specialty plans might put it in a higher tier if they’re trying to limit brand‑name usage.

How to find out for your plan
1. Check the electronic formulary – most insurers provide an online formulary or app where you can search “Crestor” or “rosuvastatin.”
2. Call the pharmacy benefit manager (PBM) – the PBM’s customer service can tell you the current tier and copay structure.
3. Ask your pharmacist – they can look up your plan’s tier status quickly.
4. Review your insurance card – sometimes the tier is printed on the back, though this is rare.

What if you’re on Tier 2?
- Ask for a generic: If you’re okay with a generic rosuvastatin, it might be cheaper and could be in Tier 1.
- Prior authorization: Some plans require prior authorization for brand‑name statins; discuss this with your prescriber.
- Check for discounts: Many manufacturers offer co‑pay cards or patient assistance programs for rosuvastatin.

Bottom line
Crestor can be in either Tier 1 or Tier 2 depending on the insurer and the specific plan you have. The best way to know is to look up your plan’s formulary or ask your pharmacy. If cost is a concern, consider the generic alternative, which is usually cheaper and often in a lower tier.
