What is the non-deductible criterion related to insurance premiums?

The answer relating to the non-deductible criterion for insurance premiums is the payments for loss of life or limb. This is correct because life insurance premiums are generally not tax-deductible, and the proceeds from life insurance policies are also typically not taxable for the beneficiaries. Thus, payments made in connection with loss of life or limb do not qualify for tax deductions.

In contrast, the other options involve medical expenses or costs associated with healthcare. Medications prescribed for chronic health issues, routine doctor visits during illness, and procedure costs covered by Medicare can all be associated with deductible medical expenses under certain conditions. Medical expenses, including prescription medications, qualify as deductible when they exceed a certain percentage of the taxpayer's adjusted gross income (AGI), making them valid for deduction claims when filing taxes.
