Yes, under Section 80D, the whole amount paid for health insurance (as well as the GST paid on the insurance premium) qualifies for a tax deduction. This is because the relevant portion of the income tax legislation states that "any amount paid" for medical insurance premiums is eligible for a deduction. However, note that how much tax deduction you will receive will be based on the total paid premium and the tax laws applicable at that time. These deductions-related changes usually take place annually.
