Aetna vs. Anthem (2026 Comparison)


Aetna vs. Anthem: ACA Health Insurance

As of January 1, 2026, Aetna no longer offers ACA marketplace plans. Anthem is now the only option between the two for ACA health insurance coverage. Anthem operates in 13 states and offers HMO, EPO, POS and PPO plans, with an average Quality Rating System score of 83.3. 

When we reviewed Aetna and Anthem across all three health insurance product lines in our analysis, the clearest pattern was coverage breadth. Aetna operates in more states, carries more plan types and earns higher CMS Star Ratings across every Medicare Advantage plan category. Anthem's two edges are PPO monthly premiums and HMO-POS out-of-pocket limits. For ACA coverage, Anthem is now the sole option.

Anthem's average ACA denial rate of 22.7% is nearly five percentage points above the national average of 18%. On a plan you're choosing partly because the premiums are manageable, a denial rate 4.7 percentage points above average means more claims rejected at the point of care. In my view, for anyone with a chronic condition or regular prescriptions, it's the number that should be driving the ACA decision, not premium alone.

Anthem is the only option here, so the question isn't which carrier wins, it's whether Anthem's pricing is worth accepting. In our analysis, Anthem's HMO rate of $683 per month is only $5 above the national average. That's a manageable gap. The PPO at $874 is $71 above the national average, which adds up to $852 per year in premium above what the average PPO buyer pays elsewhere. If you need PPO flexibility and live in one of Anthem's 13 states, compare Anthem's PPO against Bronze or Silver HMO options, for some buyers, the trade-off doesn't pencil out.

Aetna vs. Anthem Medicare Supplement

Aetna is the stronger choice for Medicare Supplement plans, offering seven plan types across 44 states compared to Anthem's four plans in 12 states. Both use Attained Age pricing, meaning premiums increase as you age. Aetna also has high-deductible versions of Plans F and G, while Anthem doesn’t.

Aetna vs. Anthem Medicare Advantage

Aetna is also the better Medicare Advantage option, with broader availability across 43 states compared to Anthem's 12 and a higher average CMS Star Rating of 3.88 versus 3.56. Its $0 premium share is also wider: 62% of Aetna plans carry no monthly cost, versus 44% for Anthem. Both insurers offer HMO, HMO-POS and PPO plan types with enhanced drug benefits.

Bottom Line

Aetna is the stronger choice for most people comparing these two insurers. In our analysis, it offers broader state availability, lower premiums and higher CMS Star Ratings across Medicare Advantage, and its Medicare Supplement rates are cheaper than Anthem's at every shared plan level.

For ACA coverage, Anthem is your only option between the two. Aetna exited the marketplace on January 1, 2026. Anthem's 22.7% denial rate is above the national average, worth factoring in if you have frequent care needs.

For Medicare Advantage PPOs, Anthem's lower monthly premium ($37 vs. $88) is worth considering if you're healthy and unlikely to hit your annual limit. But Aetna's $2,015 lower average MOOP for PPO plans provides better protection in a high-use year. Get quotes from both if you're in one of Anthem's 12 states, the right answer depends on how much care you actually use.
