Most life insurance companies will not provide life insurance for someone with systemic Lupus, but there are several insurers that will accept people with non-systemic Lupus.
Often, these life insurance plans for people with Lupus may have a graded benefit, meaning you wouldn't get the full death benefit immediately from the start of your life insurance policy, but after 2-3 years it would be full coverage.
There are also guaranteed issue life insurance plans that can provide life insurance protection for people who have Lupus.
