Head-to-head

Aetna

Strengths in Missouri

Strong CVS/MinuteClinic integration, $0 OTC card on most MAPDs, broad national network, well-rated drug formularies.

Watch-outs

Specialist authorization can slow non-CVS care; some markets have narrower local hospital coverage.

UnitedHealthcare

Strengths in Missouri

AARP partnership = strongest brand recognition; broadest Medigap availability; nationwide PPO networks.

Watch-outs

Higher Part D premiums in some plans; renewals sometimes shift formulary tiers.

Which fits which buyer?

  • Pick Aetna if your existing doctors / specialists are already in their Missouri network and you value strong cvs/minuteclinic integration, $0 otc card on most mapds, broad national network, well-rated drug formularies.
  • Pick UnitedHealthcare if you'd benefit more from aarp partnership = strongest brand recognition; broadest medigap availability; nationwide ppo networks.
  • Don't pick either until we've checked your specific drugs and doctors against both formularies. Either carrier may exclude a key prescription that the other covers — and switching mid-year is hard.

The real answer is plan-specific, not carrier-specific. Aetna and UnitedHealthcare each write 6-15 different MAPD plans in Missouri. The right plan for you might be from the carrier you didn't expect. We do the comparison for free in 14 minutes.
