A Medicare Advantage Plan is an all-in-one alternative to Original Medicare. These plans cover everything included in Medicare Parts A and B and often include Part D prescription drug coverage combined into a single policy. Many options feature predictable monthly premiums and generally do not include a medical deductible. While these plans typically utilize a provider network, some may allow you to seek care out-of-network at a different cost-sharing level. Additionally, Medicare Advantage plans often include various extra benefits beyond what is covered by Original Medicare.
