How do I tell if Mom has LTC insurance?

How do I find out if my mother has long term care (LTC) insurance? She also has Blue Cross/Blue Shield insurance, which she pays out of pocket. Would there be any way to get some in-home help (cleaning,shopping, running errands, etc) through this insurance company? How can I check? I have heard that in some polices there is coverage for up to 20 hours a week.
