What documentation is required for paying health insurance by credit card?

Blue Cross charges my health insurance premium to my credit card each month automatically. I do not sign a separate credit card authorization each month and I do not get a receipt. Will the credit card statements be enough for tax purposes, or do I need to request an actual receipt from the insurance company?|||Yes. You wouldn't need to show proof unless you were examined or audited, and the credit card statements would suffice as proof of payment.
