Best Medicare Advantage Plans: PPO vs HMO vs MSA Compared

Overview

When it’s time to choose a Medicare Advantage plan, you’ll quickly run into terms like PPO, HMO, and MSA. These acronyms describe how your plan works — from network restrictions to prescription coverage and even how you manage costs. Enrollment in these plans continues to grow, with the latest Medicare Advantage enrollment trends showing record numbers of beneficiaries choosing private coverage.

Many people also wonder about changing plans over time, since switching Medicare Advantage plans without penalties is allowed during certain enrollment periods.

In this article, we’ll compare Medicare Advantage PPO vs HMO vs MSA plans, highlight pros and cons, and help you determine which is the best Medicare Advantage plan for your care style.

What Are Medicare Advantage Plans?

Medicare Advantage, also called Part C, bundles hospital, medical, and often prescription drug coverage into one plan offered by private insurers approved by Medicare. If you’re still learning the basics, our overview of Medicare Part C explains how these plans work alongside Original Medicare.

The three main plan structures are:

• HMO (Health Maintenance Organization): Lower costs, but tighter provider networks.

• PPO (Preferred Provider Organization): More flexibility with doctors and specialists.

• MSA (Medical Savings Account): High-deductible plan with a Medicare-funded savings account.
