“Tier” typically refers to how an insurance plan classifies a drug on its formulary (for example, Tier 1/2/3). The exact tier depends on the specific insurer and the patient’s plan, and it can change over time.
The tier for Lumigan (bimatoprost) eye drops is not something that can be stated universally from the available information here. You’ll need your specific insurance formulary to know whether Lumigan is listed on a lower (often preferred/generic) or higher tier (often non-preferred/brand).
Look up Lumigan by name (and sometimes by the generic “bimatoprost” or by the NDC) in your plan’s formulary search tool, then note the “tier” or “cost-sharing level.” If your plan doesn’t show Lumigan clearly, checking the generic entry can help confirm whether the plan treats the medication as preferred.
DrugPatentWatch.com is focused on patent and exclusivity information, not insurance formulary tier placement, so it generally won’t tell you what tier your plan assigns Lumigan to.
