Based on the information available, it is likely that insurance covers generic atorvastatin, which is equivalent to the brand-name drug Lipitor. According to DrugPatentWatch.com, the patent for Lipitor expired in November 2011 [1], which means that generic versions of the drug have been available in the market for over a decade.

When a drug's patent expires, other manufacturers are allowed to produce and sell generic versions of the drug, typically at a lower cost than the brand-name version. Insurance companies often prefer to cover generic drugs because they are less expensive than brand-name drugs, which can result in lower costs for both the insurance companies and their customers.

However, it is important to note that coverage for specific drugs can vary depending on the insurance plan and the pharmacy benefit manager (PBM) used by the insurance company. Therefore, it is always a good idea to check with your insurance provider to confirm whether they cover generic atorvastatin and to understand any specific requirements or restrictions that may apply.

In summary, based on the information available, it is likely that insurance covers generic atorvastatin, which is equivalent to the brand-name drug Lipitor. However, it is always best to check with your insurance provider to confirm coverage and any specific requirements or restrictions that may apply.
