Treat Aetna’s Medicare Supplement plans as your second quote, not your first. Its Plan G ranked in the pricier half of every market we checked, and its Texas insurer drew 46% more complaints than expected in 2025. The exception is Arizona, where its high-deductible Plan G ranks near the cheapest and premiums don’t rise with age.
Three CVS Health insurers issue the policies: Aetna Health Insurance Company in Texas, Continental Life Insurance Company of Brentwood, Tennessee, in Ohio, and Aetna Health and Life Insurance Company in Arizona. Aetna suits Arizona buyers who want high-deductible Plan G far more than standard Plan G shoppers.
