Lipitor is a prescription medication used to lower cholesterol levels in the blood. It is classified as a statin drug and is sold under the generic name atorvastatin. As per the sources, there is no clear indication that Lipitor is not covered for pre-existing conditions. However, the coverage for Lipitor may depend on the type of insurance plan you have.

If you have Original Medicare (Part A and Part B), you may want to consider purchasing a Medigap policy to help cover the costs of Lipitor. Medigap policies are supplemental insurance plans that can help cover the out-of-pocket costs associated with Original Medicare, such as copayments, coinsurance, and deductibles. However, Medigap policies do not cover prescription drugs, so you would need to enroll in a separate Medicare Part D plan to get coverage for Lipitor.

If you are traveling to the United States and looking for travel medical insurance that covers pre-existing conditions, the Premier Plan offered by American Visitor Insurance may be an option. This plan provides coverage for pre-existing conditions as long as the policy is purchased within 14 days of the initial trip deposit and the insured is medically able to travel at the time of purchase.

In conclusion, while there is no clear indication that Lipitor is not covered for pre-existing conditions, the coverage for Lipitor may depend on the type of insurance plan you have. If you have Original Medicare, you may want to consider purchasing a Medigap policy to help cover the costs of Lipitor. If you are traveling to the United States and looking for travel medical insurance that covers pre-existing conditions, the Premier Plan offered by American Visitor Insurance may be an option.
